Description
Technical Field
The invention relates to the technical field of display, in particular to a manufacturing method of a display panel.
Background
The cut-in-place technology (MCP, Multi-Chip Process) is often used in the manufacturing of display panels, which can cut a plurality of smaller display panels suitable for different models on a large display panel. The sizes of the cut display panels are usually inconsistent, and the arrangement directions of the color resistors between the display panels suitable for different models are mutually vertical during typesetting, so that the display panels suitable for different models cut from the same display panel have the problem that LC Margin (the liquid crystal quantity corresponding to the box thickness has upper and lower limits, and the middle value of the upper and lower limits of the liquid crystal quantity is LC Margin) and the display quality are inconsistent.
The liquid crystal amount injected into the liquid crystal display panel determines the cell thickness thereof, and the external pressure or the gravity of the glass substrate may cause the liquid crystal display panel to have a phenomenon of uneven cell thickness, which may affect the display characteristics of the liquid crystal display panel, such as light transmittance, contrast, response speed, etc., so that a Spacer unit is required between the upper and lower glass substrates of the liquid crystal display panel as a support, for example, a Post Spacer or Photo Spacer (PS) is currently formed by a photolithography process as a support. The columnar spacer plays a role in maintaining the gap between the TFT substrate and the CF substrate, i.e., in maintaining the thickness of the liquid crystal cell to be stable. Two kinds of columnar spacers are generally provided in the liquid crystal cell: one is a Main columnar spacer (Main PS) for normally maintaining the thickness of the liquid crystal cell, and the other is a Sub-columnar spacer (Sub-PS) for supporting the liquid crystal cell only when being pressed by an external force.
According to the design requirements of the liquid crystal display panel, the main columnar spacers and the auxiliary columnar spacers are orderly arranged in a display area (AA area) of the liquid crystal display panel according to a certain arrangement rule and distribution density, however, the existing arrangement rule of the columnar spacers cannot improve the section difference between the main columnar spacers and the auxiliary columnar spacers.
As the lcd panel is developed to have a large size and a high resolution, the size of the pixels of the lcd panel is getting smaller and smaller, after the cell formation process is completed, the switching elements such as the semiconductor layer of the tft and the column spacers are sequentially arranged side by side along the first direction, and if the process is shifted along the first direction, the column spacers as the spacer units risk standing outside the sub-pixels, which reduces the LC margin and the rate of the main column spacers or the rate of the auxiliary column spacers (i.e. the total area of the main column spacers or the total area of the auxiliary column spacers in the effective display area is divided by the area of the effective display area); if the process attempts to shift in a second direction opposite to the first direction, this in turn causes the columnar spacer to be too close to the semiconductor layer on the TFT substrate side, the columnar spacer runs the risk of pushing up against the semiconductor layer, resulting in a decline in the performance of the liquid crystal display panel.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
FIG. 1 is a schematic diagram of an exemplary cut-in of two display panels (i.e. module 1 and module 2) for two different models, the auxiliary spacing units 3 of the module 1 and the module 2 are vertically arranged according to the trend of Gate lines (Gate lines) at the side of a Thin Film Transistor (TFT), when the module 1 and the module 2 are designed, the sizes of the auxiliary spacing units 3 of the module 1 and the module 2 are the same (the sizes comprise the length, the width and the height of the auxiliary spacing units 3), due to the influence of the exposure scanning on the auxiliary spacing units 3 (the exposure scanning direction is along the X or Y direction), after the exposure scanning, the heights of the auxiliary spacing units 3 of the module 1 and the module 2 are not consistent, so that the respective offsets of the module 1 and the module 2 are not consistent (the offset is the height of the main spacing unit 4 minus the height of the auxiliary spacing unit 3), therefore, the display panels which are cut from the same display panel and are suitable for different models have the problems of LC Margin and inconsistent display quality. Furthermore, the existing arrangement rule of the spacing elements 3, 4 does not promote the level difference between the main spacing element 4 and the auxiliary spacing element 3. With the development of large-size and high-resolution liquid crystal display panels, the size of pixels of the liquid crystal display panels is smaller and smaller, and after the box forming process is completed, the spacing units in the module 1 and the module 2 run the risk of standing outside the sub-pixels.
