4-inch square 720*720 touch screen LCD module MIPI brightness 400 player display 86 switch panel

TXW395039S0-HYE 86 switch panel dedicated display module

The TXW395039S0-HYE display module, designed specifically for 86 switch panel scenarios, has become an ideal choice for smart home control interfaces due to its precise size adaptation, clear display effects, and convenient touch experience.

1,Product positioning
TXW395039B0-HYE is a "small-sized, fully integrated, and highly integrated" display solution designed for smart homes, industrial control, and portable devices. It is between 3.95 inches in size and integrates a 720 × 720 high-resolution IPS screen, 4 Lane MIPI high-speed interface, and G+F+F capacitive touch, balancing image quality, touch experience, and structural space. It is an ideal choice for scenarios such as the 86 type intelligent switch panel, player, fresh air unit panel, small appliances, and industrial HMI.

The module size is 3.95 inches, and the external dimensions are precisely controlled at 84.3784.373.23 (mm), which is highly compatible with the installation specifications of the standard 86 type switch panel. It can be seamlessly integrated into the panel structure, ensuring sufficient display area (71.93 * 70.93mm) without occupying additional space, meeting the compact design requirements of the switch panel.

The working temperature range covers -20 ℃~70 ℃, which can adapt to the seasonal temperature differences in different regions, ensuring stable operation in both cold winter and hot summer. The storage temperature range is -30 ℃~80 ℃, ensuring the reliability of the product during transportation and storage. The 4 Lane MIPI 30PIN display interface is paired with the ST7703I driver chip to achieve stable data transmission and display control, reducing the impact of electromagnetic interference on display performance in home environments.

2,Core Highlights
Retinal level clarity
* 720 × 720 square pixel array with a pixel density of up to 261 PPI, with sharp and jagged edges for text and icons.
* IPS wide viewing angle technology, horizontal/vertical 178 ° without color deviation, meets the needs of multi angle viewing.

400 nits highlighted display
* Typical brightness of 400 nits, combined with IPS high contrast, the image remains transparent even in strong living room or factory lighting.
* Brightness consistency<10%, ensuring no visible bright spots when the UI background is solid color.

Fully bonded G+F+F capacitive touch
* The OGS structure (G+F+F) tightly adheres the protective glass, touch sensor, and display module, compressing the thickness to 3.23 mm, making the entire machine thinner.
* 10 point touch, supports gesture sliding/zooming; The touch IC adopts mature GT911, algorithm anti-interference, and can also recognize water operation.
* The I ² C interface only requires 2 communication cables, simplifying motherboard wiring.

Highway 4 Lane MIPI DSI
* 4 data channels MIPI, theoretical bandwidth of 1 Gbps/Lane, can easily drive 60 Hz 720 × 720 video streams.
* 30PIN FPC plug-in connection, integrated TE synchronization signal, reduces tearing; Compatible with mainstream Linux/Android/RK/ESP platform drivers.

Industrial grade reliability
* The working temperature is -20 ℃~+70 ℃, and the storage temperature is -30 ℃~+80 ℃, covering both severe cold and high temperature conditions.
* ESD contact 8 kV, air 15 kV protection, passed 48 hour salt spray and 10-200 Hz random vibration testing, suitable for industrial sites.

3,Structural dimensions
Appearance: 84.37 mm × 84.37 mm × 3.23 mm, square design, with four corner positioning holes for easy insertion into 86 boxes.
Display area: 71.93 mm × 70.93 mm, with a screen to body ratio of 85%, leaving a larger visible area for the UI.
