Due to its high performance ratio and low cost, TFT liquid crystal displays are used more and more in automotive configurations, and have become the mainstream of automotive audio and video systems and automotive navigation system displays. With the development of artificial intelligence, the content of vehicle display will continue to be enriched, and the specifications of vehicle LCD panels will also increase day by day. High-definition display quality, high brightness, large size, wide viewing angle, thinning, light weight, high reliability, low power consumption, etc. will become the future development trend of on-board displays.
The central control area of some cars is still dominated by traditional structural solid buttons, and the high-end version of some cars uses a touch screen. The design concept of physical buttons greatly limits the interior design, and the space utilization rate is low, which hinders the passenger space in the front row. At the same time, the central control needs to set up corresponding functional areas, such as the central control screen, air conditioning area, vehicle control area, etc., which will complicate the central control area and is not conducive to user operations. Users must find the corresponding button operation among the numerous buttons, and must also adapt to the arrangement of the central control buttons of different models. Compared with the touch screen used in the consumer electronics field, the touch screen used in the automotive field should have the following characteristics:
(1) Large-scale touch screen.
(2) Support multi-touch.
(3) It has high reliability.
(4) Has high durability.
Among them, large-scale and multi-touch are mainly to meet the user's experience, which is the same as the trend of electronic consumer goods. At the same time, the automotive field has put forward higher requirements for touch screens, which require high reliability and high durability. These characteristics embody the specific requirements of the automotive field for the central control touch screen of the TFT liquid crystal display.
With the development of intelligence, the touch screen in the car has also become the mainstream. In response to this trend, panel manufacturers have developed new technologies in the field of in-vehicle displays to occupy a favorable market position. Large-size, high-definition multi-function integrated vehicle touch panels will become a standard configuration. At the same time, the vehicle panel needs to be able to be affected by the driving environment, outdoor strong light and high temperature, and the vehicle navigator with resistive or capacitive touch screen has strong anti-interference ability.
