Problems solved by technology

[0004] However, the existing technology for locating bad positions can only be applied to the display screen in the state of a module with an integrated circuit. For a single display screen that has not yet been equipped with an integrated circuit, it can only be marked manually with a marker pen, and the Searching in a large area under a microscope leads to low work efficiency and high labor intensity for poorly located positions

Embodiment 1

[0086] Such as figure 1 and figure 2 As shown, a display screen monomer proposed in Embodiment 1 of the present invention includes: an array substrate and a liquid crystal unit arranged on the array substrate, and the array substrate is connected with a monomer test data signal source, a plurality of row driver unit GOA in figure 1 The specific correspondence is (GOAoutput1-GOAoutputn) and multiple data lines Data figure 1 The specific correspondence among them is (Data1-Datan); N positioning pixel switches 1, the positioning pixel switches 1 include a control terminal 10, a first terminal 11 and a second terminal 12, each of the first positioning pixel switches 1 The terminals 11 are respectively connected to a data line Data, and the second terminal 12 of each positioning pixel switch 1 is respectively connected to a row driving unit GOA, for inputting the signal in the row driving unit GOA into the data line Data ;Multiple enable elements (EN)3 in figure 1 The specific...

Embodiment approach

[0090] 1. The number of positioning pixel switches can be the same as the number of columns of pixel switches on the array substrate, and the number of rows of pixel switches on the array substrate is M; M is a positive integer greater than or equal to 2; and the number N of positioning pixel switches is less than that of the array substrate The number M of rows of pixel switches.

[0091] Specifically, such as image 3 The dark area in the figure shown is the setting position of the positioning pixel switch, and the positions of the N positioning pixel switches in the array substrate are located in the first column, the first row, the second column, and the third row of the array substrate. , the third column, the fifth row... near the pixel switch of the Nth column and the N+N-1 row; or as Figure 4 The dark area in the figure shown is the setting position of the positioning pixel switch, and the positions of the N positioning pixel switches in the array substrate are locat...

Embodiment 2

[0110] Embodiment 2 of the present invention proposes a system for locating the defective position of a single display screen, which includes: a control device, a lighting machine, and a single display screen; the single display screen includes: an array substrate and a The liquid crystal unit on the array substrate is connected with a single test data signal source, a plurality of row drive units GOA figure 1 The specific correspondence is (GOAoutput1-GOAoutputn) and multiple data lines Data figure 1 The specific correspondence among them is (Data1-Datan); N positioning pixel switches 1, the positioning pixel switches 1 include a control terminal 10, a first terminal 11 and a second terminal 12, each of the first positioning pixel switches 1 The terminals 11 are respectively connected to a data line Data, and the second terminal 12 of each positioning pixel switch 1 is respectively connected to a row driving unit GOA, for inputting the signal in the row driving unit GOA into ...

Abstract

The invention is about a display screen unit, and a bad position positioning system and method for the display screen unit, and relates to the technical field of visible light communications. The maintechnical solution is that: the display screen unit comprises the following parts: an array substrate and a liquid crystal unit disposed on the array substrate; N positioning pixel switches, comprising control ends, first ends and second ends, wherein the first ends of respective positioning pixel switches are respectively connected to data lines correspondingly, and the second ends of respectivepositioning pixel switches are respectively connected to row driving units correspondingly; and a plurality of enabling units, wherein the output ends of respective enabling units are respectively connected to the gate lines of the respective rows of driving units in the array substrate, the number of enabling units is the same as that of rows of pixel switches in the array substrate, and N is apositive integer greater than or equal to 2. The display screen unit provided by the invention can locate a bad position by means of a lighting machine and a control device by row-by-row and column-by-column lighting.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a single display screen, a system for locating the defective position of a single display screen and a positioning method thereof. Background technique [0002] In the display manufacturing industry, during the manufacturing process, some tiny foreign objects often lead to defective lines and dots on the display screen. When analyzing the above-mentioned defective locations, it is often difficult to locate them at the microscopic level. [0003] In order to solve the above problems, in the prior art, under the cooperation of the lighting machine and the computer, by controlling the output of the integrated circuit, and sending a specific picture or controlling the timing of the integrated circuit, the crosshair picture is displayed on the display screen to locate the bad position. [0004] However, the existing technology for locating bad positions can only be applied to the dis...
