مقدمة المنتج:COM22H2P80ULC مقدمة المنتج

The Ortustech COM22H2P80ULC is a 2.2-inch TFT-LCD display module featuring Ortustech’s proprietary Blanview transflective technology, which enables excellent outdoor readability under direct sunlight while maintaining low power consumption. The panel has a QVGA resolution of 240 x 320 pixels in portrait orientation, with 262K color depth and 35% NTSC color gamut. The VA (Vertically Aligned) normally-black display mode provides a high contrast ratio of 800:1 (typical, transmissive mode) and wide viewing angles of 80° in all four directions. The module achieves 400 cd/m2 brightness with a 3S1P WLED backlight system rated for 50,000 hours of operation. The display uses a CPU interface with a 40-pin connector and operates from a 2.8V supply. With an outline dimension of 38.64 x 53.72 x 4.55 mm and weight of only 11g, it is ideal for compact handheld terminals and portable devices.

مبدأ العمل:COM22H2P80ULC مبدأ العمل

The COM22H2P80ULC uses TFT-LCD (Thin Film Transistor Liquid Crystal Display) technology with a VA (Vertically Aligned) normally-black mode. Each pixel contains three sub-pixels (RGB) controlled by individual TFT switches. In the default state (no voltage applied), the liquid crystal molecules are vertically aligned, blocking light and producing a black state. When voltage is applied across the LC layer, the molecules tilt, allowing light to pass through — the degree of tilt controls the gray level. The Blanview transflective technology combines transmissive (backlight) and reflective (ambient light) modes: in bright ambient conditions, the reflective layer utilizes sunlight to illuminate the display, reducing backlight power consumption while maintaining visibility. The color filter array (RGB vertical stripe) generates the full color gamut. The 40-pin CPU interface accepts parallel data and control signals from the host MCU, with the display refreshing at 60 Hz. The WLED backlight (3 LEDs in series, 1 parallel string) provides uniform illumination through a light guide plate.
