Color TFT-LCD uses thin film transistors to generate voltage to control the liquid crystal steering display. It consists of a glass plate with a thin film field effect transistor matrix circuit and a glass plate with a color filter. Liquid crystal is poured between the two glass plates. Each pixel in the display is divided by the horizontal and vertical common metal wires of the thin film transistor matrix circuit. Each pixel contains a thin film field effect transistor and a capacitor. This capacitor is composed of an indium tin oxide (ITO) transparent electrode in the matrix circuit and a common ITO electrode on the color filter. The liquid crystal sandwiched between the two electrodes acts as a dielectric in the capacitor.

Liquid Crystal Displays (LCDs) are widely used in everything from smartphones and televisions to industrial equipment and medical devices.

Stretched bar screen is a commercial display product with an ultra-wide LCD displays. In It is widely used in vehicle display(bus, subway guide screen), retail or supermarket shelves, Banking counter and other fields. There are sizes range from 11.3 inch to 86 inch. The average luminance is 700nit. JDA support customize length and width of stretched bar display to meet different needs.

OLED stands for Organic Light Emitting Diode. It is a cutting-edge display technology that offers stunning image quality by using organic compounds that emit light when an electric current is applied. Unlike traditional LCDs, OLED displays do not require a backlight. Each pixel in an OLED display is self-illuminating, which allows for deeper blacks, higher contrast, and more vibrant colors.

With the development of technology and the growth of usage demands, the touchscreen filed has undergone a gradual upgrading process from low-end to high-end. In modern electronic devices, touch screens have become an important part for HMI interaction. According to the working principle, the touchscreen can be divided into two major categories: resistive RTP touch screens and capacitive CTP touch screens. They each have their own characteristics and are suitable for various application scenarios.

From the structure of the screen, we roughly divide the screen into three parts. From top to bottom are the protective glass, TP, and display screen, and these three parts need to be bonded. There are three types of lamination processes, including frame lamination, zero lamination and full lamination technology.
