Display Modules - LCD, OLED, Graphic

The MT7DPVG2F-A1S is a multi-touch LCD display module that can be found in a variety of applications. It is a low-power and high-performance display module featuring a 7" WVGA display and an integrated multi-touch controller.

This module provides a wide variety of features, such as an ultra-high definition picture quality with a resolution of 800×480; wide view angle; smooth transition between brightness levels; and a variety of color reproduction grades. The module supports resistive and capacitive type multi-touch screens with a maximum of 5 points of contact. It is also fully integrated with a host of other features, such as a 3-axis accelerometer, a 3-axis magnetometer, and a micro-SD card.

The MT7DPVG2F-A1S can be used for a variety of applications, including industrial, consumer, medical, and automotive applications. Some of these applications include handheld, portable, and in-vehicle displays. It can also be used in a variety of embedded applications, such as navigation, gaming, surveillance, monitoring, and control systems.

Working Principle

The working principle of the MT7DPVG2F-A1S is based on the use of a liquid crystal display (LCD). LCDs are a type of flat panel display that use liquid crystals that can be manipulated using electric signals. When a voltage is applied to the liquid crystal molecules, they change their alignment and thus change the color or amount of light being transmitted.

The LCDs used in this module are a type of twisted nematic (TN) LCDs. In this type of LCD, the liquid crystal molecules are twisted in such a way that they can either be in an ON state or an OFF state. The ON state enables light to be transmitted, while the OFF state blocks light from passing. This is how the pixels on the screen are created, by controlling the voltage applied to the different crystalline structures.

The MT7DPVG2F-A1S module is also equipped with a multi-touch controller. This controller is responsible for tracking and detecting the multiple touch points on the display. It collects and processes data from the touch screen and sends the appropriate signals to the application processor. The data collected by the controller is used to determine the location and type of touches, as well as their pressure.

Conclusion

The MT7DPVG2F-A1S is a low-power and high-performance display module featuring a 7" WVGA display and an integrated multi-touch controller. It can be used for a variety of applications, including industrial, consumer, medical, and automotive applications. The working principle of this module is based on the use of an LCD and a multi-touch controller, which are responsible for controlling the display and processing touch input data.
