LQ038Q5DR01 Design and Structure
The LQ038Q5DR01 is designed with a flat rectangular structure. It is thin and light, making it suitable for portable devices and embedded systems. The panel uses a-Si TFT technology, allowing each pixel to be controlled independently. The display area is focused in the center, with pixels arranged in vertical RGB stripes. The dot pitch and pixel pitch are 0.082×0.2235 mm and 0.246×0.2235 mm, respectively. The module surface has anti-glare and anti-reflection treatment to reduce ambient light interference. With four front-mounting holes on the left and right flanges, it is easy to install and supports multiple mounting methods.
Structurally, the LQ038Q5DR01 panel is composed of a color TFT-LCD panel, driver ICs, control-PWB, FPC, frame, front shielding case, back-light unit. It uses TN display mode, supporting normally white display and transmissive imaging. The brightness of subpixels is controlled by a 6-bit grayscale signal, allowing the screen to show 262K colors. The backlight uses a single-side, edge-lit CCFL lamp, achieving a high brightness of 450 cd/m². For electronic connections, the module provides a Parallel RGB (1 channel, 6-bit) TTL interface, simplifying connection to the main control device.
Additionally, the panel offers a standard interface layout, making it easy to connect to various control boards and systems. Its design also considers heat dissipation and electromagnetic compatibility, ensuring long-term operation in industrial environments.

How to Connect Sharp LQ038Q5DR01?
Before connection, make sure you understand the main parameters of the module. It uses a Parallel RGB (1 channel, 6-bit) TTL signal interface. Check the official datasheet for the pin definitions. Pay attention to three key pin types: power, signal, and ground. Vdd (pin 16) and Vgg (pin 9) are power pins. RF in/out (pins 4, 16) and ACG1–4 (pins 22, 23, 10, 11) are signal pins. Pins 3, 15, and 17, as well as the chip pad, should be connected to RF/DC ground. N/C pins (such as pins 1 and 2) can be grounded if needed.
Connect the wires in the order of “power → ground → signal.” First, connect Vdd and Vgg to the rated voltage, and place bypass capacitors near the Vgg and ACG pins. Then, connect all ground pins securely to the system ground to reduce interference. Finally, connect the module's RGB signal pins to the TTL interface of the main controller one by one, making sure the timing matches. If you need to change the display direction, you can set it to flip 180° through the controller.
Before powering on, check all wiring to make sure there is no reverse connection or short circuit. For the first power-on, it is recommended to use a low voltage to confirm that the module lights up normally. Note that the CCFL backlight requires an additional driver module, and the driver parameters must match the lamp (530 ± 60 V voltage, 5.5 ± 0.5 A current) to avoid brightness problems.
