quality TFT LCD Display & TFT LCD Module factory

When selecting a suitable LCD display module, the following three key indicators need to be considered first.   Display resolution: The number of pixels of the LCD display module must be greater than the maximum number of pixels required for the product display content.   External dimensions: The size of the LCD display module must adapt to the structural dimensions of the product chassis.   Circuit coordination: The selection of the LCD display module circuit will directly affect the circuit design of the MPU system. Circuit integration requires a comprehensive consideration by comparing MPU system resources and module circuit characteristics.   Built in driver LCD display module, equipped with MPU with LCD display driver, such as ARM9 series.   Built in controller LCD display module, and the controller has multiple models with unique performance, such as those with Chinese character library, those with 2D graphics accelerator, and those with only display RAM, which can meet the needs of various MPU systems.   Interface form between module and MPU: parallel interface, divided into INTEL8080 and MC6800 timing; Serial interface, including 3-wire/4-wire SPI serial interface, RS-232 interface, and I2C bus interface.   Adaptation with MPU system logic power supply: The power supply voltage of the module is also consistent with the module interface signal level, requiring the working power supply and signal voltage of the module to be consistent with the power supply and signal level provided by the MPU system, reducing the level conversion circuit for signal connections.   Power consumption of the circuit: It is necessary to evaluate whether the MPU system power supply can support the working state current, sleep state current, backlight current, etc. of the circuit.

The current market price of Samsung LCD splicing screens often leads people to overlook the essence of their specialized products, due to the increasing popularity of LCD splicing screen applications. Especially due to the popularity of concept marketing, many industry users are at a loss. Therefore, before making a purchase, industry users must clarify their own application needs and avoid pursuing trends. Moreover, it is worth mentioning that the application effect of LCD splicing screens is not only related to the quality of their own products, but also depends on appropriate solutions. This is directly linked to the comprehensive strength of the manufacturer. Industry users of Huabangying Technology Co., Ltd. must consider comprehensively when making a purchase.   LCD splicing screen is undoubtedly one of the most widely used display terminals in the current large screen display market. Shopping malls, subway stations, command and dispatch centers, and other places can be seen everywhere, and the constantly expanding application scope has made LCD splicing screens a true mass commodity. Sensorily speaking, people are not unfamiliar with them. However, due to the increased professionalism of LCD splicing screens and the increasingly diversified marketing gimmicks of manufacturers, superficial solutions cannot provide direction for industry users' actual purchases. To buy products with high cost-effectiveness and strong applicability, the following things must be clarified.   These things need to be clarified! Practical LCD splicing screen selection.   The thinner the LCD splicing screen, the better. Thickness is not an independent factor. In large screen display applications, it has always been. LCD splicing is known for its ultra-thin design, and based on marketing demands, thinness has become a key packaging target for businesses. This has led to industry users paying attention to the thickness of products when making purchases? So, in practical applications, is it really better for LCD splicing screens to be thinner?   The thickness of Samsung LCD splicing screens is no exception. In terms of advantages, everything has two sides. For example, the thinner the LCD splicing screen, the more beautiful the screen body will be; At the same time, the thickness of the product also directly affects the response time. Relevant studies have shown that reducing the thickness of the spliced large screen by 20 will increase the response speed by 35 on the original basis, and so on. There are also many shortcomings that come with it. For example, the thinner the product, the higher the requirements for the manufacturing process. Once the process is not up to standard, not only will the color displayed on the screen become dim, but the viewing angle will also decrease. At the same time, the probability of bad pixels appearing on the screen will increase, and the product scrap rate will decrease. This means that to produce lightweight products, the production interest will be greatly increased, and the application interest of the product will naturally increase.   Industry users who want to choose lightweight products need to have a higher budget, which means. Choose a big brand with guaranteed quality and after-sales service to prevent unnecessary trouble. If the budget is limited, one should not be tempted by cheap prices just to catch up with the trend, as long as they are applicable.   Daily applications should pay attention to the color difference of LCD splicing screens during rest. Color difference free is also a key advantage promoted for LCD splicing screens, in addition to being lightweight. Especially in comparison to DLP splicing screens (which may experience color fading after a period of use), does LCD splicing screen really have no color fading? The answer is definitely no. After long-term application, LCD splicing screens will also experience color attenuation, and this attenuation is irreversible. However, currently, manufacturers have certain adjustment methods, which is a key concern for users when purchasing   It is worth noting that it can continue to run for 7x24 hours, "although it is a key target in the marketing promotion of LCD splicing screen manufacturers. However, in practical applications, LCD splicing screens also need to rest appropriately, otherwise it will affect their service life - related studies have found that LCD splicing screens working continuously at full load for more than 96 hours will accelerate their aging, and in severe cases, they may even burn out. In practical applications, it is best for users to allow the LCD splicing screen to rest intermittently. If conditions do not allow, they can try changing the display content of the screen at different time intervals to allow the screen body to adjust slightly while waiting for the working state.   Pay attention to marketing traps. The physical resolution of the LCD splicing screen cannot be adjusted. The resolution of LCD splicing screens has always been a key concern for industry users, as it is related to the display effect. It is also a key consideration for industry users when choosing products. The resolution commonly referred to in LCD splicing screens here refers to the physical resolution of the LCD display, which represents the highest pixel parameter that can be displayed on the LCD screen and cannot be adjusted. The higher the physical resolution, the higher the clarity of the LCD screen.   The maximum support for 1920x1080p resolution has become a common promotional tactic for businesses, driven by the trend of high-definition. However, it is worth emphasizing that this only represents that the LCD display can support the signal input format of 19201080, and the physical resolution of the panel may not necessarily reach 19201080, which may also be the minimum resolution limit of the 1366x768 national high-definition display standard. If it is the latter, in actual operation, only the 19201080 signal needs to be converted into the 1366768 format that conforms to the panel output through image changes and then presented to the audience, and there will be compression and loss of image display effect during the process. Industry users must pay more attention in actual purchasing.   This is two different things: visual perspective and broad perspective. Wide perspective is undoubtedly a common object. Generally speaking, Samsung LCD splicing screens are used in daily marketing. The "wide-angle" in merchant marketing refers to the viewing angle of LCD splicing screens, which allows users to clearly observe all content on the screen from different directions. Wide viewing angle refers to the angle at which the color deviation of the LCD splicing screen reaches a certain level. Currently, due to inconsistent measurement standards, the results obtained are not necessarily the same, and are not a specific numerical value. At present, the viewing angle of LCD splicing screens is above 178 degrees, which can be considered as achieving an absolute viewing angle effect.

1. It is prohibited to open the splicing screen without the guidance of professional personnel LCD splicing screens are known for their high precision and delicacy, unlike ordinary CRT LCD splicing screens where components can be easily replaced. Another issue is that the transformer in the background lighting component of the LCD splicing screen may still have a high voltage point of 1000V after a certain period of shutdown, and if not handled properly by non professionals, it may cause new component failures and permanent screen malfunction, bringing not only economic losses but also many troubles to the user. So no matter what problems occur with the LCD splicing wall, it is forbidden to assemble the LCD splicing screen by oneself. If there is any problem with the screen, the first reaction is to seek solutions from the splicing screen manufacturer.   2. LCD splicing screens should avoid displaying the same image for a long time and require appropriate rest during use Long term overloaded work can easily cause certain pixels of the LCD splicing screen to overheat, and if exceeded, it can lead to permanent damage. The pixels of LCD splicing screens are composed of liquid crystals, and the full load usage time of liquid crystals is 96 hours. Therefore, when the full load working time of LCD splicing screens exceeds 96 hours, aging and even screen burn-in may occur. So it is reminded that users should pay attention to the usage time and avoid long-term work when using LCD splicing screens. This not only extends the lifespan of the LCD screen, but also delays the aging process and even avoids hardware damage. Another thing is that the displayed content often changes to avoid overheating of local pixels and irreparable bad pixels (black dots) caused by prolonged display time of the same image. The best way to display the same image for a long time is to perform one or two image changes in the middle.   3. How to correctly distinguish the flickering phenomenon of LCD splicing screens Occasional flickering on LCD splicing screens (this is the process of imitation/digital conversion) is an inevitable situation, mainly due to the influence of the imitation signal output interface, such as the clock and phase of pixels not being synchronized with the imitation signal output, which can also lead to flickering phenomenon. This phenomenon is usually called "PixelJitter". To solve this problem, there is usually an "automatic setting" function on LCD splicing screens, which analyzes the input signal and adjusts the LCD splicing screen to the best state. Of course, it can also be adjusted by the phase and clock functions. However, if there is regular flickering or frequent unexplained flickering, it needs to be checked. If the problem of poor cross-sectional contact is ruled out, otherwise it is a LCD splicing screen. It has malfunctioned on its own.   4. Try to avoid collisions with other objects during transportation and installation Due to the high content of precision glass and electronic components in LCD splicing screens, they have become more delicate. With limited impact resistance, strong impacts can cause damage to the LCD splicing screen and other related components. Additionally, pressure should not be applied to the surface of the LCD splicing screen, even with simple finger clicks on the screen.   5. How to scientifically and reasonably clean LCD splicing screens The LCD splicing wall is prone to accumulate dust and dirt on the surface over time. When the dust reaches a certain thickness, it will affect the display effect of the LCD splicing large screen. At this time, cleaning the LCD splicing screen is inevitable. We need to use scientifically reasonable cleaning methods when cleaning: use soft, non fiber materials such as degreasing cotton, lens paper, or soft cloth dipped in a small amount of glass cleaner to gently wipe off dust or dirt on the screen. When cleaning, it is prohibited to use organic chemical solvents such as alcohol, and rough fabrics or paper items should not be used, as these substances are hard and can easily cause scratches on the screen, affecting the display effect. Also, be careful not to spray the cleaning agent directly onto the surface of the display screen to avoid internal short circuits and irreversible losses.   6. The usage environment of LCD splicing wall must be continuously dry This is the primary condition for the normal operation of LCD splicing screens, as the interior of LCD splicing screens is composed of precision electronic components. If the usage environment is too humid, the internal electronic components are prone to oxidation and corrosion, which can affect the circuit. Over time, short circuits can occur, directly affecting the use. If water accidentally enters the interior of the machine, it is best to place the entire LCD splicing unit in a well ventilated area. It is best not to use the splicing screen with electricity without ensuring that the interior of the machine is dry, in order to avoid permanent damage to the splicing screen.   If you are not familiar with splicing screens, try to follow the operating instructions as much as possible. Even if there are faulty problems, do not disassemble and inspect them without authorization. You should consult the splicing screen manufacturer you purchased to solve the problem

Touchscreen all-in-one machines can be divided into two types of touch screens: infrared touch screens and capacitive touch screens. Each type of screen has its own characteristics and touch methods, and capacitive screens are slightly more expensive than infrared screens in terms of price. Let's take a look at the differences between infrared screens and capacitive screens together!     1. Infrared touch screen characteristics   The surface of the infrared screen has concave grooves, which ensures reliability and response speed without any running or jumping errors.   An infrared screen is composed of infrared transmitting and receiving sensing components mounted on the outer frame of a touch screen, creating an infrared detection network on the surface of the screen.   2. Characteristics of capacitive touch screen   Characteristics of infrared touch screen: Capacitive touch screen is lighter in appearance, looks more beautiful and easy to clean. The capacitive screen is entirely flat and not susceptible to light hazards, making it easy to achieve waterproof performance while also demonstrating more flexible speed.   Capacitive screens work through magnetic induction of body current, with more agile touch, no delay time, no need for forceful pressing, and good permeability.   Purchase proposal:   1. Available specifications: 32 inches (none). The following are capacitive touch screens. You can choose capacitive touch or infrared touch for sizes between 32 inches and 55 inches. Infrared touch screens are recommended for sizes above 65 inches. Choose capacitive touch for ultra small sizes and infrared touch for large sizes.   2. Price comparison: 32 inch~55 inch capacitive touch is more expensive compared to infrared touch.   3. Touch sensitivity: Ultra small capacitive touch sensitivity exceeds infrared touch, while large-sized infrared touch sensitivity exceeds capacitive touch.

There are many types of touch screens on the market, the most common of which are resistive touch screens (RTP), capacitive touch screens (CTP), surface acoustic wave touch screens, and infrared touch screens. The most widely used touch screens currently include capacitive touch and resistive touch. The capacitive screen works by using the human body's current induction, while the resistive screen works by pressure sensing.       Touch technology   Capacitive screen: Supports multi touch, fast response speed, and sensitive response.   Resistive screen: pressure sensing, can be touched with any object.     Usage environment   Capacitive screen: It is easily affected by changes in environmental temperature, humidity, electric fields, and other factors. We can optimize the display screen according to the usage scenario.     Resistive screen: The screen is not easily affected by dust, water vapor, and oil stains, and can be used in environments with lower or higher temperatures. It can adapt to harsh environments.     cost Capacitive screen: Compared to resistive touch technology, the cost is higher.   Resistive screen: Due to the mature capacitive touch technology, simple structure, and low technical threshold, the cost is relatively low.   service life   Capacitive screen: Capacitive touch technology works by using current induction, with minimal wear and tear on the screen and a long service life.     Resistive screen: Resistive touch technology utilizes pressure sensing, which can easily wear down the screen and damage the touch function, resulting in a short service life.     Anti damage ability   The outermost layer of a capacitive screen is a protective layer of silica glass, which may shatter under severe impact. The outermost layer of a resistive screen is a thin film, which is prone to scratches but less prone to breakage compared to a capacitive screen.   Pixel accuracy     Capacitive screens can theoretically achieve several pixels, while resistive screens have an accuracy of at least a single display pixel.
