Abstract

The invention discloses an optical touch panel and a light guiding module thereof. The optical touch panel comprises a panel and a light guiding module, wherein the light guiding module is arranged on the panel, the light guiding module comprises a circuit board, at least one light-emitting component and a light guiding strip, the light-emitting component is electrically arranged on the circuit board, and the light guiding strip is arranged on the circuit board and covers light-emitting component. In addition, light is emitted by the light-emitting component, and the light passes through the light guiding strip and is shot to the panel.

Description

Technical field [0001] The invention relates to an optical touch panel, in particular to an optical touch panel with a light guide module. Background technique [0002] In recent years, the input method of touching the screen with an object or a finger has begun to replace the previous input method of pressing a mechanical button. When the user touches the graphics on the screen, the tactile feedback system on the screen converts the detected light data into electronic signals and transmits them to a processor, and the processor drives various electronic devices with pre-programmed programs. And show vivid audio-visual effects through the screen. [0003] The existing tactile feedback system includes a glass substrate, a light emitting diode (LED), a photosensitive element, a lens, a reflective element, and a light guide element. The photosensitive element, the light emitting diode and the lens are arranged on the upper right corner of the glass substrate, and the reflector and t...
