With its high performance ratio and low cost, TFT LCD has caused a significant increase in the proportion of automobile equipped with LCD, and will become the mainstream of vehicle audio-visual system and vehicle navigation system display. However, with the continuous enrichment of broadcast content, the specifications of vehicle LCD are also increasing day by day, such as high precision display quality, high brightness, large size, wide viewing angle, thin, lightweight, high reliability, low power consumption and so on.

The basic specifications of vehicle LCD must with anti-dust and anti-seismic functions. In terms of temperature, it must be able to withstand the high-low temperature difference of - 30 ℃ ~ + 85 ℃ and 120 ℃, because the liquid crystal in the LCD will freeze in the low-temperature environment, resulting in the failure of normal display or the complete destruction of display ability.

In the future, the resolution of vehicle LCD will be 800 × 400 and higher, the screen will also expand within a certain range, so as to avoid the embarrassment of watching the screen too intensively due to the small screen during driving. Furthermore, the LCD panel with single screen and dual display function has also been developed by the industry. In this way, the two display devices in single display panel can independently adjust the screen update rate, resolution and color depth, and can support different applications.
