Abstract

Provided is a capacitive touch control display device comprising a light source driving laminating layer, at least a light source and a screen printing laminating layer. The light source is configuredon the light source driving laminating layer, and the screen printing laminating layer is re-printed on the light source and the light source driving laminating layer. The light source driving laminating layer comprises at least one light source switch, a first power supply and a data line connected to a grid electrode of the light source switch. The light source switch and the light source are connected in series between the first power supply and a second power supply. The screen printing laminating layer comprises an extending conductive layer adjacent to a touch control surface of the capacitive touch control display device, is electrically connected to the first power supply or the second power supply, and located between the touch control surface and the light source driving laminating layer. The first power supply, the second power supply or the data line outputs at least a touch control signal to sense the position of the touch control surface in contact with a user. A drivingmethod of the capacitive touch control display device is also proposed.

Description

technical field [0001] The present invention relates to a touch device and its driving method; in particular, it relates to a capacitive touch display device and its driving method. Background technique [0002] In the development of existing display technologies, micro LEDs (Micro LEDs), which miniaturize Light Emitting Diodes (LEDs), have become one of the main development topics in flat panel display technologies. Different from organic light-emitting diodes, micro light-emitting diodes are a technology developed from inorganic light-emitting diodes. They inherit the characteristics of high efficiency, high brightness, high reliability, and high-speed response time of inorganic light-emitting diodes. The self-luminous display technology of the backlight light source is helpful in saving energy, reducing volume and thickness. [0003] Although the micro-LED display device belonging to the self-luminous display technology can omit the thickness of the backlight module, whe...
