2.11-inch WXGA High-Brightness TFT-LCD Display Module with IPS Technology (1000 cd/m²)

Display Panel and Structure: The module employs an IPS (In-Plane Switching) TFT-LCD panel operating in normally-black transmissive mode, providing excellent color reproduction and a full (all-direction) viewing angle. The active display area measures 46.56(W) × 26.784(H) mm with a pixel pitch of 0.0582 × 0.0558 mm, and the module outline is 51.858 × 34.934 mm with a thickness of approximately 4 mm. The panel is capable of rendering up to 16.7 million colors (8-bit RGB), delivering vivid and accurate imagery for information-dense industrial interfaces.

Driver and Interface: The module is driven through a 40-pin FPC interface (RGB 24-bit + SPI). The pin assignment includes a 24-bit parallel RGB data bus (R0–R7, G0–G7, B0–B7), dot clock (CLKN), horizontal sync (HS), vertical sync (VS), data enable (DEN), a system reset pin, and an SPI configuration interface with chip select (SPI-CS), serial clock (SPI-SCL) and serial data (SPI-SDA) pins. The logic power supply is 3.3 V, and the LCD driver supply voltages are VSP = 6.3 V and VSN = 6.3 V (±0.2 V), with a typical frame frequency of 60 Hz. The 3-wire SPI interface enables register configuration of the display controller for precise timing and panel settings.

Backlight System: The module is equipped with a high-performance backlight unit containing 10 white LEDs. The LED forward current is 30 mA with a typical forward voltage of 13.3 V (at IF = 30 mA). The backlight is specifically engineered to achieve an outstanding module luminance of 1000 cd/m², which is approximately 2–3 times brighter than standard industrial LCD panels, ensuring clear readability even under direct sunlight or high ambient light conditions. The LED lifetime is defined as the time for brightness to decay to 50% of the initial value; operating the LEDs at higher current, temperature or humidity will reduce the lifetime.

Electrical and Environmental Performance: The module operates within a temperature range of −20 ℃ to +70 ℃ and can be stored between −30 ℃ and +80 ℃, covering typical industrial operating environments. Absolute maximum ratings specify these same temperature limits under humidity conditions at Ta = 25 ℃. The panel's liquid crystal driving voltage varies with environmental temperature due to the characteristics of the LC material, so proper temperature-aware voltage configuration is recommended for extreme environments.

Reliability and Quality: The JT020WXI30RSR02 has passed a comprehensive reliability test suite including high-temperature storage (80 ℃, 96 hours), low-temperature storage (−30 ℃, 96 hours), high-temperature operation (70 ℃, 96 hours), low-temperature operation (−20 ℃, 96 hours), high-temperature/high-humidity operation (40 ℃ / 85% RH, 96 hours), thermal shock cycling (0 ℃ to +50 ℃, 20 cycles), and vibration testing (10–150 Hz, 100 m/s², 120 minutes). These tests confirm the module's suitability for rugged industrial deployments.

Usage Precautions: The display panel is made of glass and must not be subjected to mechanical shock. The polarizer surface is soft and easily scratched; contamination should be removed with a soft dry cloth moistened with isopropyl or ethyl alcohol only — never water, ketone or aromatic solvents. The logic circuit power must be on before applying input signals, and ESD precautions (grounded handling, grounded tools, proper humidity) are required. For long-term storage, keep the module at 0–40 ℃ with relative humidity ≤ 80%, away from direct sunlight, acids, alkalis and harmful gases.
