1. System-Level Architecture and Pixel Domain Physical Definition

This product is a highly integrated In-cell touch-embedded IPS LCD module, adopting a 720×RGB(H) × 720(V) equilateral pixel orthogonal array. The driving and touch sensing signal processing are fully integrated into a single JD9365TX all-in-one main control chip, which completely eliminates inter-layer light loss and structural tolerance accumulation of traditional external CTP stacks.

The optical path architecture adopts a transmissive normally black active matrix driving mode. The pixel arrangement follows the RGB Stripe orthogonal rule, and a 10-bit Gamma correction link is used to achieve 16.7M full color gamut rendering. The signal transmission layer adopts a 4-lane MIPI D-PHY high-speed differential interface, which suppresses EMI radiation and long-distance signal attenuation through differential impedance matching design, achieving a 360° full viewing angle color shift control index of ΔE<2.

The overall stack outline dimension is 93.67mm(W) × 96.87mm(H) × 2.15mm(T). The tolerance of key assembly dimensions is controlled within ±0.15mm, and the unmarked general stack tolerance is uniformly converged to ±0.20mm. The physical dimension of the device's Active Area (A.A) is 91.368mm(W) × 91.368mm(H). The window design of the matching touch cover plate needs to meet the requirement of extending 0.3mm~0.5mm unilaterally beyond the A.A area to avoid signal attenuation and touch dead zones of edge touch channels.

2. Absolute Rating Domain and Environmental Stress Boundary

The ultimate tolerance thresholds of all devices are calibrated through Environmental Stress Screening (ESS). The power-on operating temperature of the entire LCM covers the range of -20°C to +70°C, and the non-power-on long-term storage temperature tolerance range extends from -30°C to +80°C. The whole device with strengthened glass cover can realize stable touch sampling in the full temperature range under the non-condensing humidity environment of 20%RH~90%RH. The temperature and humidity tolerance boundary in the storage state is fully aligned with the whole device, meeting the wide-range deployment requirements of outdoor mobile terminals and semi-outdoor industrial equipment.

3. Multi-Rail Electrical Domain Characteristic Calibration

The module I/O power supply domain supports 1.8V~3.3V adaptive voltage input, and the default typical operating voltage is set to 1.8V. The power supply topology adopts an independent dual-rail external input architecture. The typical positive input voltage of the DC/DC boost circuit is 6V, and the typical negative input voltage is -6V. The reference level of all peripheral pins, including the hardware reset pin and I2C touch communication pin, is uniformly clamped at 1.8V, which eliminates the latch-up effect and device breakdown risk caused by cross-interface level mismatch at the hardware bottom layer.

The backlight unit adopts an edge-lit light guide plate uniform light architecture, with 20 high CRI white LEDs built in. The forward conduction voltage range of the LEDs is 14V~16.5V, and the forward driving current under rated working conditions is set to 80mA. The peak brightness of the whole device with fully bonded LCD and touch layers is to be calibrated, and the minimum threshold of backlight in-plane brightness uniformity is ≥80%. The nominal LED lifetime defined in this document is the continuous operation time when the axial brightness of the whole device attenuates to 50% of the initial value under the constant current drive of 20mA per LED, with a nominal value of 30000 hours. If it operates for a long time under the overload condition where the current of a single LED is greater than 25mA, the actual MTBF index of the backlight will show nonlinear attenuation.

4. FPC Signal Link Pin Definition

The flexible printed circuit (FPC) matched with the module is led out with 30 gold finger pins in total, and all signal pins are completed with impedance matching and function solidification: Pin 1 is the backlight anode power supply terminal, Pin 2 is the backlight cathode power supply terminal, Pin 3 is the analog signal ground, Pin 4 is the 1.8V I/O domain main power supply terminal, Pin 5 is the NC no-connection pin, Pin 6 is the DC/DC positive voltage external input pin, Pin 7 is the DC/DC negative voltage external input pin, Pin 8 is the digital signal ground, Pins 9~23 correspond to the four groups of differential data pairs, differential clock pairs and supporting isolated ground terminals of the MIPI interface in sequence, Pin 24 is the 1.8V hardware global reset pin with active low level, Pin 25 is the digital signal ground, Pin 26 is the 1.8V I2C touch serial clock pin, Pin 27 is the 1.8V I2C touch serial data pin, Pin 28 is the 1.8V touch interrupt open-drain output pin, Pin 29 is the 1.8V touch hardware reset pin, and Pin 30 is the power ground.

5. Reliability Verification and Qualification Criterion System

This product fully passes six categories of environmental reliability verifications. The qualification criteria for all test items are uniformly defined as no abnormality in all functions. Failure modes such as missing pixels, row/column drive short circuit, picture fogging, no backlight output, excessive display color shift, and liquid crystal cell thickness deformation leading to liquid leakage are not allowed. At the same time, structural defects such as low-temperature liquid crystal layer bubbles, edge sealing adhesive layer peeling, and inter-stack stress rainbow patterns must not occur.
