China 3.17 inch touch screen 320*480 Manufacturers, Suppliers, Factory

Liquid crystal display is a kind of flat panel display. It is used for the screen display of TV and computer. The advantages of the display are low power consumption, small size and low radiation.

Therefore, TTL (LVDS) is the screen cable, transmitting digital signals; RGB (VGA) is the external cable, transmitting analog signals—this is the fundamental difference.

Shenzhen Hongjia Technology has successfully mass-produced the 4.45-inch TFT LCD screen, model HJ4450-01. This 4.45-inch horizontal screen LCD features IPS full viewing angle, 1920*1080 resolution, a MIPI interface, and a high refresh rate of 120Hz.

First of all, the advantage of incell LCD screens is that they are thinner and lighter than traditional TFT displays because they integrate the touch sensor and display layer into a single layer. Traditional TFT LCD screens require external mounting to fit the touch screen, which increases the thickness. In addition, the touch screen also requires a separate design of a cable, which will occupy the space inside the machine. Incell LCD screens only need to be attached to a layer of glass cover to form a complete LCD touch screen assembly, which makes them ideal for portable devices such as smartphones and tablets. The reduction in thickness and weight makes the design more compact and stylish, which is very important for the trend of thinner and more portable devices.

The HJ2101-02 is a 2.1-inch round LCD with a MIPI interface, supporting a variety of resolutions, including 540*540, 480*480, and 360*360. Compared to the 480*480 2.1-inch round screens on the market, it offers higher-definition, finer-grained displays with more vivid and lifelike colors.
