Abstract
The utility model relates to displays, in particular to a liquid crystal display with a touch screen, which is composed of a backlight module and a display panel, wherein the backlight module comprises a light guide plate and a backlight lamp, and the display panel comprises the touch screen, a liquid crystal display panel, a first flexible circuit board and a main circuit board. The liquid crystal display with a touch screen is characterized in that an output end of the main circuit board is a USB interface. Because the output end of the main circuit board is a USB interface, electrical signals generated by the touch screen is analyzed by a touch screen control circuit and then is transmitted to a computer via the USB interface and data exchanging lines, and the computer analyzes and sends signals to a display driving chip A/D board which is connected with the liquid crystal display via the data exchanging lines. The utility model has simple structure, resolves the problem that connecting lines at the inside of the liquid crystal display with a touch screen are complicated and interfered with each other, thereby greatly increasing the image quality.
