Problems solved by technology

However, when the transmission lines in the touch panel are scanned, they are easily affected by the voltage levels of the scan lines in the original display panel of the flat-panel display.
When the voltage level on a certain transmission line is always disturbed by the voltage level on the scanning line, it is easy to cause misjudgment and mistakenly regard the interference as the touch of an external force

Abstract

A display device includes a first panel, a first control unit, a second panel and a second control unit. The first panel has a plurality of scan lines. The first control unit turns on the scan lines according to a first turn-on sequence. The second panel has a plurality of transmission lines. The second control unit turns on the transmission line according to a second turn-on sequence. The first turn-on sequence is different from the second turn-on sequence.

Description

technical field [0001] The present invention relates to a display device, in particular to a display device with two panels. Background technique [0002] Because of its excellent picture quality and low price, image tubes have been used as monitors for televisions and computers. However, with the advancement of technology, new flat panel displays have been developed one after another. The main advantage of the flat-panel display is that when the flat-panel display has a large-sized display panel, the overall volume of the flat-panel display does not change significantly. [0003] In order to improve the convenience of the flat-panel display, a touch panel is usually provided on the surface of the flat-panel display, so that the user can click on the screens and options presented on the display by touching them. However, when the transmission lines in the touch panel are scanned, they are easily affected by the voltage levels of the original scan lines in the display panel...
