Embodiment Construction

[0020] As mentioned in the background art, in the prior art, the screen display detection and the TP function detection are separately detected, which leads to technical problems of cumbersome procedures and complicated processes. The reason why such a problem arises is as follows. Before the display panel is assembled as a whole, it is necessary to test the screen display and touch function of the display panel. Screen detection checks the display panel for black spots, bright spots, and Mura (the name of Mura comes from a Japanese word, specifically referring to panel defects, which is used to represent the unevenness of the display area when the panel is displayed at a constant brightness). The touch detection is to detect the touch flexibility and feedback degree of the display panel through different touch operations on the display panel. For example: click on the display panel to make the display panel stay on a certain fixed screen; or input a specific letter and an im...

Abstract

The invention provides a picture and touch control joint detection module, which is located on a display driving integrated circuit of a display panel and comprises an image storage unit, a core processing unit, an image output unit and a touch control recognition unit, wherein the core processing unit sequentially and circularly calls image detection image information from the image storage unitto the image output unit, the display panel circularly displays the picture detection images in sequence through the conversion of the image output unit so as to realize picture detection, and the core processing unit stops the sequential and circular calling of the picture detection image information according to a first touch control instruction sent by the touch control recognition unit and calls the first touch control detection image information corresponding to the first touch control instruction from the image storage unit to the image output unit, so that the display panel stays on thefirst touch control detection image according to the first touch control operation, the feedback degree of touch control can be preliminarily detected, and image detection can be further carried out.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a joint detection module of screen and touch, a joint detection method of screen and touch, and a display device. Background technique [0002] Before the whole machine is assembled, the screen display and touch panel (Touch Panel, TP) function of the display panel need to be tested. In the prior art, the screen display detection and the TP function detection are performed separately, requiring different detection boards and detection procedures, and the separate detection procedures are cumbersome and complicated. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a combined screen and touch detection module to solve the technical problems of cumbersome procedures and complicated processes caused by separate detection of screen display detection and TP function detection in the prior art. [0004] According to one asp...
