AT070TN83 V1 is a 7" a-Si TFT-LCD, LCM Display screen Product from INNOLUX.According to INNOLUX's product specification sheet,AT070TN83 V1 display has a resolution of 800(RGB)×480, Contrast Ratio is 1000:1,Viewing Angle is 70/70/50/70,Lamp Type is WLED , 20K hours , With LED Driver,Signal Interface is TTL (1 ch, 6-bit) , 40 pins Connector,Brightness is 400 cd/m².Based on its characteristics, this model is recommended for application in Intelligent Wearing and other products.The weight of AT070TN83 V1 after packaging is 1.000KG.We have made every effort to minimize weighing variances; however, we cannot guarantee absolute accuracy.
How can I drive this screen on a Linux system (e.g., using Allwinner F1C100s)?
A:
To drive it under Linux, you need to configure the Device Tree to correctly describe the screen's timing parameters (like pixel clock, front/back porch, sync pulses) and the backlight control pin. You can look for configurations of similar panels in the Linux kernel source as a reference, or write the device tree node manually based on the screen's datasheet.
Q:
What are the viewing angles and brightness of this display?
A:
ccording to its datasheet, the AT070TN83 V1 typically has a brightness of 400nits (cd/m²). For viewing angles, it's typically 70/70/50/70degrees (Left/Right/Up/Down).
Q:
Is the AT070TN83 V.1 compatible and interchangeable with other versions like V.2?
A:
Usually not directly interchangeable. Although they share the same size and resolution, different versions (V1, V2) may have minor differences in pinout, backlight parameters, or initialization sequences. Always check the specific version's datasheet for confirmation before replacemen
Q:
What voltage does the backlight of this screen require and how do I light it up?
A:
The WLED (White LED) backlight of this screen typically requires around 20V driving voltage. You cannot connect it directly to a 3.3V or 5V power supply. A dedicated LED boost driver circuit or constant current source is mandatory. This backlight driver circuit is usually integrated on the evaluation board.
Q:
What interface does this AT070TN83 V1 screen use and how do I connect it to my development board?
A:
This screen uses a standard 24-bit RGB parallel interface. You will need a main control board with the same RGB interface (like Allwinner F1C100s, some STM32 models) or a converter board (like an SSD1963 driver board) to drive it. When connecting, ensure the pinout of the screen matches your driver board exactly
