Embodiment Construction

[0014] see figure 1 , figure 1 It is a schematic structural diagram of an embodiment of a display panel air bubble detection system of the present invention, and the detection system includes:

[0015] The collision body 10, specifically, the collision body 10 may be a sphere, a cube, a cuboid, etc., and its material may be metal or plastic.

[0016] The driving device 12 includes a driving element 121 and a moving element 122. The driving element 121 drives the moving element 122 to move, and the moving element 122 hits or drives the collision body 10 to hit the display panel 14 to measure the bubble condition of the display panel 14; specifically, the above-mentioned The moving direction of the moving element 122 is toward the display panel 14 , so that the moving direction of the collision body 10 is also toward the display panel 14 . In one application scenario, the moving element 122 is integrally formed with the collision body 10, that is, the collision body 10 is one ...

Abstract

The invention discloses a bubble detection system and a bubble detection method for a display panel. The detection system comprises a collider and a drive device, wherein the drive device comprises a drive element and a motion element; the drive element drives the motion element to move; the motion element collides with the collider or drives the collider to crash into the display panel to measure the bubble condition of the display panel, wherein the motion direction of the motion element faces toward the display panel. According to the bubble detection system and the bubble detection method for the display panel, the accuracy of the bubble detection result can be improved.

Description

technical field [0001] The invention relates to the field of display panels, in particular to a system and method for detecting air bubbles in a display panel. Background technique [0002] Color filter on array substrate (Color Filter on Array, COA) technology is a process technology that makes color-resist material on the glass side of array substrate (Thin Film Transistor, TFT). This technology has small alignment error and can The parasitic capacitance is reduced, and the display panel prepared by using this technology has better resolution and higher pixel aperture ratio. [0003] However, in the above-mentioned technology, the color resist is made on the side of the array substrate, which increases the complexity of the manufacturing process on the side of the array substrate, making the display panel prone to bubbles. At present, a method for detecting bubbles in a display panel is: applying a certain force to the display panel to accelerate the accumulation of bubbl...
