LQ035Q7DB03 Application Field and Working Principle

The LQ035Q7DB03 is an active matrix color a-Si TFT-LCD (Thin Film Transistor - Liquid Crystal Display) module. It features a full viewing angle, high resolution and image performance for use in various electronic devices. This module is mainly used for the display of electronic products including home appliances and digital photos.

Application Field

LQ035Q7DB03 displays have a wide range of uses. They are used in industrial products, including medical products, navigation systems, in-vehicle displays and other test instruments. The LQ035Q7DB03 is also used in consumer products, including laptop displays, digital cameras, PDAs, and mobile phones.

Working Principle

The working principle of the LQ035Q7DB03 is the same as that of other LCD displays. It is composed of two transparent glasses and they contain liquid crystal molecules with a nematic structure. The crystals in the nematic structure will tend to align in a particular way when an electric field is applied to them. By varying the voltage applied to the crystals, power is used to adjust the amount of light passing through the crystals. By applying different voltages, the light can be modulated in a way to produce different images on the display.

In the LQ035Q7DB03, light is delivered to the display by a backlight, which is usually composed of a light source and a light guide plate. The backlight illuminates the liquid crystal layer, and the desired image is then projected onto the display. The image consists of tiny dots (pixels) composed of three sub-pixels - red, green, and blue - which are arranged in a three-by-three grid.

The LCD display panel is composed of hundreds of thousands of thin-film transistors (TFTs) which switch between two voltage levels - 0V and 5V - to turn on and off each pixel. This is achieved by applying a small electrical current to each sub-pixel, which controls the amount of light that is allowed to pass through the crystal to the display panel.

The LQ035Q7DB03 display panel has the capability to maintain a high quality image without experiencing any noticeable fading of the image. This is due to the display panel\'s ability to utilize liquid crystals, which provide a higher contrast ratio and improved viewing angle than other LCD displays.
