Problems solved by technology

These backlights can be produced by attaching reflective strips or luminous strips to the edge of the display surface of the screen, but this will increase the complexity and cost of the mechanism at the same time
Furthermore, the method of capturing dark spots is also easily affected by ambient light
Specifically, when ambient light shines on a finger or a touch object and is reflected back to the image sensor, dark spots cannot be interpreted

Abstract

A touch control screen comprises a display, at least two touch control units and a control unit. The display has a display surface. The touch control units are configured beside the display surface. Each touch control unit comprises a light source and an image sensor. The light source is configured beside the display surface and suitable to emit a beam by facing a sensing space before the display surface. The image sensor is configured beside the display surface and the sensing surface of the image sensor faces the sensing space. The image sensor is suitable to capture a light spot in the sensing space and generate an image signal. The control unit is electrically connected with the light sources and the image sensors and suitable to receive the image signals from the image sensors, as well as judges the position of the light spot relative to the display surface according to the image signals. A touch control module and a control method are also disclosed.

Description

technical field [0001] The present invention relates to a touch module, a touch screen and a control method of the touch module, and in particular to an optical touch module, a touch screen and a control method of the touch module. Background technique [0002] With the advancement of optoelectronic technology, the method of using the mouse to control the objects on the work platform and the screen can no longer meet the needs of users. Therefore, an interface that is more humanized than mouse control has gradually been developed. Among these user-friendly interfaces, finger touch is the closest to the experience of human beings in daily life. Therefore, the elderly or children may not be able to operate the mouse, but they can easily use fingers to touch. Part of the proof is that some ATMs have adopted touch screens. [0003] There are many ways to realize the touch interface in the known technology. For example, in some known liquid crystal displays, a layer of touch fi...
