Abstract

The invention relates to a scan method applicable to a touch control panel and capable of increasing scan speed. The scan method comprises the steps of detecting at least one touch control area of a touch control panel, and detecting the touch control area to obtain at least one touch control point in the touch control area. The scan speed of a touch control panel can be increased by detecting touch control area of the touch control panel and then detecting the touch control point in the touch control area.

Description

technical field [0001] The invention relates to a scanning method for a touch panel, in particular to a scanning method for increasing the scanning speed applied to the touch panel. Background technique [0002] In recent years, all kinds of electronic products are constantly moving towards the direction of easy operation, small size and large screen size, especially portable electronic products have stricter requirements on volume and screen size. Therefore, many electronic products integrate the touch panel with the liquid crystal display panel to omit the space required for the keyboard or control keys, thereby expanding the configurable area of ​​the screen, and the user only needs to use a finger or a stylus to clear the touch screen. The control panel can be used to transmit information with the electronic device. [0003] see figure 1 , is a schematic structural diagram of a touch panel in the prior art. As shown in the figure, a general touch panel includes a scan...
