Problems solved by technology
However, its disadvantage is that the infrared light needs to pass through the liquid crystal panel 10, and the energy of the light is greatly attenuated. Therefore, the energy of the light emitted by the infrared LED needs to be high, so the system efficiency is low, and it is necessary to sacrifice the brightness of the white light or replace the infrared LED with a higher brightness.

Embodiment Construction
[0040] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.
[0041] figure 2 An embodiment of the optical plate structure for touch control according to the present invention is shown. The optical board structure 24 for touch control includes an optical board 26 , at least one light source 28 and at least one photodetector 30 . A light emitting surface 32 of the optical plate 26 includes a plurality of microstructures 34 . The light-emitting surface 32 refers to the surface seen by the user during use, and the light from the light source 28 is emitted from this surface and the microstructures 34 thereon. The main function of the microstructure 34 is to increase the amount of light output, and moreover, it can make the light output surface of the optical plate feel tactile and has an anti-fouling effect. There are one or more light sources 28 located...

The invention relates to a touch optical plate structure, which comprises an optical plate, at least one light source and at least one light detector. A light-exiting face of the optical plate comprises a plurality of microstructures. The light source is positioned at a vertical side of the optical plate. The light source emits a first light which enters into and is guided by the optical plate, and a second light is emitted from the light-exiting face. The light detector, which is positioned at a side or a corner of the optical plate and is higher than the light-exiting face, is used for detecting a third light, which is generated by reflecting the second light by a foreign object to the light detector when the foreign object touches the optical plate. The invention further relates to a touch display panel and a touch liquid crystal display comprising the optical plate structure for touch.
Description
technical field [0001] The present invention relates to an optical plate structure, in particular to an optical plate structure for touch control, a touch display panel and a touch liquid crystal display including the same. Background technique [0002] In today's market of various electronic products, personal digital assistants (PDAs), mobile phones (mobile phones), notebook computers (notebooks) and tablet computers (tablet PCs) have widely used touch panels as data Input interface tools. The touch panel can also have the functions of keyboard, mouse, etc. and humanized operation methods such as handwriting input. In particular, the input and output can be integrated on the same interface (that is, the display panel, or screen) to form a touch display. Panel (touch display panel). [0003] figure 1 An existing touch-type liquid crystal display panel is shown. Such as figure 1 As shown, a backlight unit is provided under the liquid crystal panel 10 . The backlight uni...
