Embodiment Construction

[0022] figure 2 It is a schematic diagram of an optical touch panel according to an embodiment of the present invention. Please refer to figure 2 , the optical touch panel 200 has a plurality of touch sensing elements 210 and a plurality of ambient light sensing elements 220 . The ambient light sensing element 220 is used for sensing the intensity of ambient light, and the touch sensing element 210 is used for sensing the position touched by the user to operate the electronic device. The touch sensing element 210 is, for example, built into a display panel, that is, the optical touch panel 200 is actually a touch display panel integrated with a display function and a touch function or a touch panel with a display function. . For example, if the design of the display panel is a Thin Film Transistor Liquid Crystal Display Panel (TFT-LCD Panel), the touch sensing elements 210 can be arranged in a thin film transistor array. In addition, the manufacturing process of these to...

Abstract

The invention discloses a driving method, which is suitable for driving an optical touch panel. The optical touch panel is configured on a backlight component and provided with a plurality of touch sensing elements, wherein each touch sensing element is provided with a shade sensing mode and a reflection sensing mode. The driving method comprises: firstly sensing the intensity of environment light; when the intensity of the environment light is larger than a reference valve, the touch sensing element carries out the shade sensing mode; and when the intensity of the environment light is smaller than the reference valve, the touch sensing element carries out the reflection sensing mode. The driving method is favorable for making the optical touch panel correctly sense under various environment lights so as to improve the use convenience of the optical touch panel.

Description

technical field [0001] The present invention relates to a driving method, and in particular to a driving method of an optical touch panel. Background technique [0002] Man-Machine Interface (MMI) refers to the communication medium between man and machine. Generally, electronic devices sold in the market are designed with a man-machine interface to allow users to perform various functions of the electronic device in order to facilitate the operation of the user. With the rapid development and application of information technology, wireless mobile communications and information home appliances, many electronic devices 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 the touch panel (TouchPanel) as an input device. Wherein, the combination of the display panel and the touch panel makes the design of the man-machine interface more convenient. [...
