What is TFT-LCD for Vehicle?

It is understood that in the In Cell TFT-LCD, the surface of the thin-film transistor substrate toward the liquid crystal layer is provided with a plurality of mutually insulated sensing lines. The thin-film transistor substrate cooperates with the touch-sensing layer to embed the touch panel functions into the liquid crystal pixels, reducing the thickness of the touch screen.

A high-resistance film is set on the surface of the second substrate away from the touch induction layer, and the high-resistance film is electrically connected to the thin film transistor base plate. The high resistance film can instantly release the static electricity generated by the thin film transistor substrates, eliminating the static electricity and reducing the interference between touch sensors, thereby improving the touch sensitivity of the embedded touch screen.

It seems that the car display market is also experiencing the road of screen technology upgrades for consumer electronic terminals represented by mobile phones. The main technical paths are overlapping, but when carefully reviewed, the challenges faced by car displays will be even greater. The reason is that automotive parts have a more stringent rules-level inspection. Unlike consumer goods and industrial products, these parts have higher reliability requirements, such as working temperature range, working stability, bad rate, etc.

The technical parameters of the high-resistance film are square resistance, transmittance, reflectivity, etc. Square resistance is usually 5E7_~5E9, which acts as ESD static protection and has no interference with TP touch control. Reflectance < 1.3%, low reflection makes it easier to achieve the display black effect.

At the same time, in order to ensure the quality of the TFT-LCD for Vehicles for a long time in various environments, it is necessary to ensure the stability of the individual. Only rigorous testing can ensure that vehicle-mounted products do not have potential problems of touch failure and ESD failure during processing, assembly, and end-use, and meet the requirements of vehicle-mounted use scenarios and durability.

As more technology giants enter the new energy automotive track, the automotive industry has entered an era of contention. With the rapid development of many independent brands, a large number of new forced car-making enterprises emerge. Rapid growth in automotive sales led by new energy automobiles will drive the increase and upgrade of supply chains such as TFT-LCD for vehicles. The demand for lightweight in-car screens is bound to increase the demand for In Cell screens, and related In Cell supply chain enterprises will also benefit.
