Embodiment Construction

[0029] figure 1 is a schematic side view of a touch display device according to an embodiment of the present invention, figure 2 yes figure 1 The top view of the touch panel of the touch-sensitive display device. Please also refer to figure 1 as well as figure 2 , the touch display device of this embodiment includes a display panel 102 and a touch panel 106 located on the display panel 102 . In one embodiment, if the above-mentioned display panel 102 is a transmissive or transflective display panel, the touch display device further includes a backlight module 104 disposed under the display panel 102 . According to another embodiment, if the above-mentioned display panel 102 is a reflective display panel, the backlight module 104 may not be required. Therefore, the backlight module 104 is not an essential component of the touch display device.

[0030] In this embodiment, the display panel 102 is a liquid crystal display panel, which includes a lower substrate, an upper...

Abstract

The invention discloses a touch panel and a touch display device which is provided with the touch panel. The touch panel comprises a light panel, a plurality of light sources and a plurality of detectors, wherein, the light panel comprises an upper surface, a lower surface, a plurality of side surfaces and a plurality of light input surfaces. The light source is arranged on the light input surfaceof the light panel, and the light source has a light bundle total reflection angle (alpha) and a light bundle vertical divergence angle (beta) relative to the light input surface of the light panel,wherein, alpha is greater than theta and less than 60 degrees, theta is the critical angle of the total reflection angle of the light panel, and beta is less than 50 degrees. The detector is arrangedin the position corresponding to the light source to receive the light bundle signals emitted by the light source. The invention can avoid the problem that the traditional optical touch panel easily generates wrong touch signals.

Description

technical field [0001] The present invention relates to a touch panel and a touch display device with the touch panel, and in particular to an optical touch panel and a touch display device with the optical touch panel. Background technique [0002] With the rapid development and application of information technology, wireless mobile communications and information home appliances, many information products have been transformed from traditional input devices such as keyboards or mice in order to achieve more convenient portability, lighter volume and more humanized operation. To use a touch device as an input device. Currently, touch panels can be roughly classified into resistive touch panels, capacitive touch panels, acoustic touch panels, optical touch panels, electromagnetic touch panels, and the like. Each of the touch panels mentioned above can be assembled with the display panel in a plug-in manner to form a touch display device. [0003] Among the optical touch pan...
