  • Patent number: 10139939
    Abstract: An optical touch screen and a display device are disclosed. The optical touch screen (200) comprises an optical touch panel (210) and a first sensor (220) and a second sensor (230). The optical touch panel (210) comprises a first optical transmission channel (211) and a second optical transmission channel (212) which are intersected with each other. The first sensor (220) is disposed on at least one end of the first optical transmission channel (211) and configured to receive light emitted by the first optical transmission channel (211). The second sensor (230) is disposed on at least one end of the second optical transmission channel (212) and configured to receive light emitted by the second optical transmission channel (212). The optical touch screen and the display device can improve the positioning accuracy of the touch position.

  • Patent number: 9563003
    Abstract: The present invention provides a liquid crystal display device, comprising: a light source, a light guide plate having a light-exiting surface, a substrate having a first surface and a second surface opposite to the first surface, a display area of the second surface comprising a pixel area and at least one non-pixel area, and a gap provided between the light-exiting surface of the light guide plate and the first surface of the substrate, wherein, at least one slot is provided on the light-exiting surface of the light guide plate; a part of the light generated by the light source and entering the light-exiting surface of the light guide plate, after being refracted by the slot and the gap sequentially, is refracted by the first surface of the substrate into the substrate, and then enters the pixel area. According to the present invention, it is able to change the light transmission path, thereby to effectively reduce the light entering a non-pixel area.
