Abstract

The invention discloses an optical touch liquid crystal display module which comprises a liquid crystal display module and at least two optical touch units, wherein the liquid crystal display module is provided with a display surface and a side surface arranged at the circumference of the display surface, and comprises a frame arranged at the circumferences of the display surface and the side surface; the frame is provided with an opening for exposing the display surface; each optical touch unit is arranged among the frame, the display surface and the side surface, and defines a sensing space in the front of the display surface; and each optical touch unit is provided with a sensing window towards the sensing space so as to sense touch objects in the sensing space through the sensing window.

Description

technical field [0001] The present invention relates to a liquid crystal display module, and in particular to an optical touch liquid crystal display module. Background technique [0002] In recent years, due to the continuous advancement of image display technology, touch screens have become a common display device on the market today because of their advantages of direct input through contact, and are widely used in various electronic products. , such as automated teller machines, point-of-sale terminals, visitor guidance systems, or industrial control systems. [0003] Today's common touch panel designs can be roughly divided into resistive, capacitive, optical, acoustic, and electromagnetic types. In the case of an optical touch LCD, generally after the LCD module is assembled, the touch unit including the light source, signal processing element, and sensing element is assembled next to the display surface of the LCD module. . However, this will easily lead to a pre-s...
