Embodiment Construction

[0019] The present invention will be fully described below with reference to the accompanying drawings showing embodiments of the invention. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, components are exaggerated for clarity.

[0020] It will be understood that when an "element" is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements may be present. In contrast, when an element is referred to as being "directly connected to" or "directly coupled to" another element, there are no intervening elements present. The same reference numerals designate the same elements. As used herein, the term "and / or" i...

Abstract

The invention provides a display device integrating a touch function and a driving method thereof. The display device integrating the touch function comprises a display unit, a touch detection circuit and a driving unit, wherein the touch detection circuit is used for touch detection to generate multiple touch detection signals, the driving unit is used for driving data refreshing of the display unit and touch detection of the touch detection circuit, and the data refreshing area and the touch detection area are not overlapped. According to the display device integrating the touch function and the driving method thereof, touch and display are driven at the same time, the charging time of display pixels is prolonged, and the problem that the charging time of the display device integrating the touch function is insufficient is solved. Meanwhile, reference voltages which are free of touch influences and reflect signal interference brought by display driver (namely, data refreshing) in real time by adding a reference unit, background noise in touch detection can be removed, the signal to noise ratio is improved, and accuracy of touch recognition is guaranteed.

Description

technical field [0001] The present invention relates to a touch screen, and more specifically, to a display device with integrated touch function and a driving method for the display device. Background technique [0002] The current touch technology generally adopts time-division driving, that is, the sequence controller time-divides a frame period into a display time T1 and a touch time T2. During the display time, the storage capacitor in the display device is charged; during the touch time, it is used to detect the touch signal, but this will shorten the charging time of the storage capacitor and affect the display effect. Contents of the invention [0003] Additional aspects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. [0004] The present disclosure provides a display device integrating a touch function, including: a display unit; a...
