Abstract

The invention provides a touch-control panel and a touch sensing method and a display device applied. The touch panel comprises a substrate, a pixel, a visible light sensing element and an invisible light sensing element. The pixel is formed on the substrate, the visible light sensing element is arranged in the pixel for sensing visible light, and the invisible light sensing element is arranged in the pixel for sensing invisible light. The invention can avoid the situation of misjudge and can be applied in the environment of low light intensity or dark state.

Description

technical field [0001] The present invention relates to a touch panel, in particular to a touch panel, a touch sensing method thereof, and a display device applied thereto. Background technique [0002] Various current electronic devices have widely used touch technology as their input method, whereby the user can use a finger or a stylus to touch the display panel to simultaneously or simultaneously transmit information and display information. Therefore, buttons, keyboards or sliders that must be configured on conventional electronic devices can be omitted. [0003] Taking the optical touch panel as an example, it uses the principle of light receiving and blocking to sense the touch of foreign objects. The optical touch panel includes a plurality of light sensors disposed on the panel, wherein the light sensors are used to sense visible light. When the ambient light illuminates the light sensor, a photocurrent can be generated; otherwise, when the light sensor is covered...
