Embodiment 1

[0022] figure 1 is a schematic structural diagram of a testing system for a display screen according to an embodiment of the present invention. Such as figure 1 As shown, the display screen testing system may include: a display screen tester 10 and a display screen 12 to be tested.

[0023] Wherein, the display screen tester 10 is connected with the display screen 10 to be tested, and is used to collect test data of a plurality of parts of the display screen to be tested, and obtain standard parameters of a plurality of parts of the display screen to be tested, and each The test data are respectively compared with the corresponding standard parameters to obtain the test results; among them, the test data of the display screen tester includes: the reference voltage value of the display screen to be tested, the high and low level of the infrared receiving head of the display screen to be tested value, high and low current values ​​and decoding results, the LED current value of...

Embodiment 2

[0057] Figure 7 It is a flow chart of the testing method of the display screen according to the second embodiment of the present invention. Such as Figure 7 The method shown includes the following steps:

[0058] In step S20, the display screen tester acquires standard parameters of multiple components of the display screen to be tested.

[0059] Step S22, the display screen tester collects test data of multiple components of the display screen to be tested, the test data includes: the reference voltage value of the display screen to be tested, the high and low level values ​​of the infrared receiving head of the display screen to be tested, High and low current values ​​and decoding results, the LED current value of the display screen to be tested, and the current value of the digital tube.

[0060] In step S24, the display screen tester compares each test data with corresponding standard parameters to obtain test results.

[0061] The test method provided by the above-...

Embodiment 3

[0086] Figure 8 is a schematic structural diagram of a testing device for a display screen according to Embodiment 3 of the present invention. like Figure 8 As shown, the testing device of the display screen includes: an acquisition module 80 , an acquisition module 82 and a test module 84 .

[0087] Wherein, the acquisition module 80 is used to obtain the standard parameters of a plurality of parts of the display screen to be tested; the acquisition module 82 is used to collect the test data of a plurality of parts of the display screen to be tested, and the test data includes: the display to be tested The reference voltage value of the screen, the high and low level values, high and low current values ​​and decoding results of the infrared receiving head of the display screen to be tested, the LED current value of the display screen to be tested, and the current value of the digital tube; the test module 84 is used for Compare each test data with the corresponding standa...

Abstract

The invention discloses a testing method, a testing device and a testing system of a display screen, wherein the method comprises the following steps: acquiring standard parameters of a plurality of parts of the to-be-tested display screen by virtue of a display screen tester; collecting test data of the plurality of the parts of the to-be-tested display screen by virtue of the display screen tester, wherein the test data include a standard voltage value of the to-be-tested display screen, a level value, a current value and a decoding result of an infrared receiving head of the to-be-tested display screen, an LED current value of the to-be-tested display screen and a current value of a nixie tube; and respectively comparing each of the test data with the corresponding standard parameters by virtue of the display screen tester, so that a test result is obtained. The testing method disclosed by the invention can solve the problem of a display screen testing method in the related prior art which is low in testing efficiency, so that an effect of improving the display screen testing efficiency is improved.

Description

technical field [0001] The invention relates to the field of testing, in particular to a testing method, device and system for a display screen. Background technique [0002] At present, the test of the split machine bar display still relies on the manual testing and judgment of the inspector. The items that need manual judgment include mask defects, aluminum foil defects, and receiving failures caused by functional failures. Manual long-term testing is very easy to cause visual fatigue, and some The scale of appearance problems is difficult to grasp, and it is easy to miss detection. It can be seen that the existing manual judgment method has a certain impact on quality control. [0003] At present, no effective solution has been proposed for the problem of low test efficiency of the display screen test method in the related art. Contents of the invention [0004] Aiming at the problem of low test efficiency of the test method of the display screen in the related art, n...
