Nowadays, the use of strip LCD screens is quite widespread, and there are also many types of strip screen products on the market. Some products from different manufacturers have significant price differences, which is very troublesome for consumers, who do not know how to distinguish and choose. Due to the different price positioning of strip LCD screens produced by various manufacturers, the quality requirements are also different. So, what are the factors that cause different prices of strip LCD screens? Let's give a brief introduction below.
1. Viewing angle of bar LCD screen
For current LCD displays on the market, the viewing angle is symmetrical, but not necessarily vertical. The vertical viewing angle is usually smaller than the horizontal viewing angle. Due to the directionality of the light source of the backlight tube after refraction and reflection, color distortion occurs when viewed beyond this range. Generally, the horizontal viewing angle is the main parameter, and the larger the value, the larger the viewing angle.
2. Brightness and contrast of bar LCD screen
Brightness is one of the important indicators reflecting the performance of liquid crystal displays. The brightness of LCD screens is measured in square candles (cd/m2) or nits, and is generally between 100-130 nits. It should be noted that data is not the entirety of product performance, and brighter products may not necessarily be better products. The key is whether the brightness is uniform, which cannot be found in the product specification manual. The uniformity of brightness is closely related to the number and configuration of light sources and mirrors. Places far away from the light source will inevitably have darker brightness.
3. Response time and refresh rate (i.e. scanning frequency) of bar LCD screen
Response time is a specific indicator of LCD displays, which refers to the speed at which each pixel of the LCD display responds to input signals, measured in milliseconds (ms). The smaller the response time, the faster the pixel response, while the longer the response time, the more severe the display tailing phenomenon when displaying dynamic images (even mouse cursor). Currently, the standard response time for LCD displays should be below 30ms.
4. Pixel spacing of bar LCD screen
The pixel pitch of a bar LCD screen is similar in meaning to the dot pitch of a CRT. However, the former is not as important to product performance as the latter. The number of pixels in LCD displays is relatively fixed, therefore, as long as the size and resolution are the same, the pixel spacing of all products should be the same. For example, a 15 inch LCD monitor with a resolution of 1024 × 768 has a pixel pitch of 0.297mm (some products are also labeled as 0.30mm).
