Problems solved by technology

For example, when mura spots appear on a large scale around the display motherboard, the main reason may be that the atmosphere of ink droplets formed during inkjet printing is not uniform
[0004] However, the above process is not only time-consuming, but also mostly requires the operator to manually analyze which columns or rows of the display panel on the display motherboard are damaged, and the analysis process is relatively cumbersome.

Embodiment 1

[0030] Embodiments of the present invention provide a statistical method for defective display panels, such as figure 1 shown, including:

[0031] 101. Read the two-dimensional code information on the defective display panel.

[0032] Among them, the two-dimensional code (2-dimensional bar code) is to record the data symbol information with a specific geometric figure distributed in the plane (two-dimensional direction) according to certain rules; The concepts of "0" and "1" bit streams that constitute the internal logic basis of the computer use several geometric shapes corresponding to the binary to represent text and numerical information, and automatically read through image input equipment or photoelectric scanning equipment to realize automatic information processing. deal with.

[0033] For example, the two-dimensional code may specifically include a Datamatrix two-dimensional barcode, a Maxicode two-dimensional barcode, a QR (QuickResponse) code, and the like.

Abstract

The embodiment of the invention provides a method and a device for counting poor display panels, which relate to the technical field of display and aim at quickly counting the distribution condition of poor display panels in a display motherboard and quickly analyzing causes of the poor display panels. The method comprises steps: two-dimensional code information on a poor display panel is read; according to the two-dimensional code information, the position information of the poor display panel in the display motherboard is determined; and according to the position information, the distribution information of the poor display panels in the display motherboard is outputted. The method of the invention can be applied to a poor display panel counting process.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a statistical method and device for defective display panels. Background technique [0002] Usually, in the LCD process, multiple display panels can be fabricated together on one display motherboard. For example, 220 5.2-inch display panels are arranged in an array in a 1.5m*1.3m display motherboard. Display panels with independent display functions are made after cutting and other processes. [0003] Among them, after cutting the display motherboard into multiple display panels, it is necessary to perform lighting inspection on each display panel to determine whether there are defects such as bright spots and mura spots on the display panel. Once a defective display panel occurs, it is necessary to unify a production batch. The defective display panels in the display panel are sent back to the production office for analysis. The operator determines the position of each defecti...
