Description
I. Product Overview
This 8.0-inch color TFT LCD Display Module (Model: TFT-H080D13XGIYZ5N40), manufactured by HOTHMI, delivers a high-definition resolution of 1024(RGB) x 768 pixels and a color saturation of 60% NTSC. Built with a normally black full-view IPS panel, this Display Module provides stable, clear, and color-accurate images from all viewing directions. With a typical brightness of 500 cd/m² and support for constant-current testing, the module measures 174.00 x 136.00 mm in outline dimension, while its active display area is 162.05 x 121.54 mm.
The Display Module is driven via a 40-Pin LVDS 4L interface, with a typical operating voltage VCI of 3.2–3.4V. Backlight driving conditions require Vf=18.0–20.0V and If=220mA. In addition, four reference voltages—VCOM, VGH, VGL, and AVDD—are needed during operation. This Display Module exhibits excellent environmental robustness, functioning reliably from -20℃ to +70℃ (with storage capability from -30℃ to +80℃), making it ideal for industrial control systems, handheld electronic devices, and various smart terminals. Its FPC gold-contact area is reinforced with a PI stiffener to ensure stable and reliable connection integrity.
II. Core Product Highlights
As a Display Module that meets high standards across all hardware specifications, the TFT-H080D13XGIYZ5N40 offers the following competitive advantages:
- IPS Full-view and High-definition Quality: With 1024(RGB) x 768 pixel density combined with IPS wide-view technology, this Display Module ensures consistently sharp, detailed, and color-accurate visuals from side, upward, or downward angles.
- 500 cd/m² Typical High Brightness: The Display Module provides 500 cd/m² brightness support, ensuring clear readability even under strong indoor office lighting, surgical operating lights, or semi-outdoor shaded environments.
- Excellent ESD Protection: Hardware design meets industrial-grade testing standards, with special support for up to 8KV electrostatic discharge protection. This effectively counters static interference in industrial production, field plugging/unplugging, or dry environments, significantly extending overall system lifespan.
- Industrial-grade Wide-temperature Operation: This Display Module supports harsh operating temperatures from -20℃ to +70℃, with storage ranging from -30℃ to +80℃, easily meeting extreme environment demands from cold outdoor settings to high-temperature factory workshops.
- High-reliability Connection Design: The FPC gold-contact backside is equipped with a PI stiffener as standard, capable of withstanding frequent insertion and withdrawal cycles while preventing poor contact caused by pin bending or vibration.

- Handheld Mobile Data Terminals: Such as high-precision mapping instruments and warehouse logistics smart handheld tablets. The ultra-slim design facilitates lightweight system integration.
- Smart Home and Building Central Control: Can be deployed as wall-mounted centralized interactive panels for high-end villas and smart office buildings, with its dead-angle-free viewing angles allowing users of varying heights to comfortably view indoor status.
V. Technical FAQ
Q1: What are the functions of the “SHLR” and “UPDN” pins on the 40-Pin interface, and how are they used?
A1: These two pins serve as hardware display flip controls for this Display Module. SHLR (Shift Left/Right) controls the horizontal scanning direction (left/right mirroring), while UPDN (Up/Down) controls the vertical scanning direction (top/bottom flipping). By connecting these pins to high level (VCI) or low level (GND) on the mainboard side, developers can achieve 180-degree rotation or mirror display directly without modifying the underlying software code of the main controller chip, greatly facilitating various physical reverse mounting configurations.
Q2: What are the strict voltage and current requirements for the backlight when driving the module?
A2: The typical brightness of this LCD Display Module is 500 cd/m², with an internal backlight composed of high-efficiency LED arrays. When driving the backlight, a constant-current (constant-current transformer) test and drive mode must be used. The datasheet specifies that the driving current If must be strictly controlled at 220 mA, with the corresponding forward voltage Vf ranging from 18.0V to 20.0V. Do not use a high-voltage constant-voltage source to drive the backlight directly, as this can easily cause LED overheating, shortening lifespan or even burning out the components.
