Embodiment Construction

[0043] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0044] Such as figure 1 and figure 2 As shown, in this embodiment, a test device and a test method for simultaneously measuring LCM (liquid crystal display module) and CTP (capacitive touch screen) are provided. The test equipment makes the signal connection between the LCM display measuring instrument and the signal connection fixture by setting the signal of the LCM display measuring instrument. By imitating the communication protocol of the IIC interface on the CTP, the LCM display measuring instrument connects the LCM display measuring instrument to the IIC interface on the CTP through the signal connection fixture, and increases the function of performing related tests on the CTP. Test the LCM and complete the CTP test at the same time, and display the CTP test results more intuitively.

Abstract

The invention relates to a test device and a test method for a display apparatus, in particular to a test device and a test method for measuring a liquid crystal module (LCM) and a capacitive touch screen (CTP) simultaneously by applying a multiplex display port mode. The test device comprises an LCM display gauge, an LCM signal connection clamp and a CTP signal connection clamp, and the LCM display gauge is in signal connection with the LCM signal connection clamp and the CTP signal connection clamp respectively; and an inter-integrated circuit (IIC) connector is arranged on the CTP signal connection clamp. According to the test device and the test method for the display apparatus, CTP functions are tested while LCM functions are tested, and interference conditions and the cooperation degree of the CTP and the LCM can be observed; computers for testing can be saved, one test process is reduced, and the test time is shortened; the accuracy testing of points and line drawing is convenient and visual; problems of pixel shifting and the like caused by prior CTP and LCM testing alone can be solved, and the testing conforms to the trend of the combining of the CTP and LCM.

Description

technical field [0001] The invention belongs to the testing field of mobile display devices, and in particular relates to a testing device and a testing method for simultaneously measuring LCM and CTP by using a multiplexed display interface. Background technique [0002] At present, CTP (capacitive touch screen) and LCM (liquid crystal display module) are checked separately. The inspection of CTP is carried out by connecting and running the test software on the computer or the host computer. The LCM is tested using the LCM Display Meter. However, with the wide application of CTP, especially in the field of mobile display, it has become a trend to integrate LCM and CTP. However, in the prior art, CTP and LCM are tested separately. On the one hand, additional testing procedures and equipment are added, resulting in an increase in cost; The matching degree of the two products is not high, and the detection accuracy is not high and the efficiency is low. Contents of the in...
