Problems solved by technology

[0009] The edge of the liquid crystal panel after cutting the slivers by the above two methods is rough, which will increase the seam width of the cutting screen; in addition, the laser and diamond scribing methods not only generate longitudinal stress, but also generate transverse stress at the same time. Cracking; the above two cutting methods need to peel off the polarizer, using the split technology, only straight cutting edges can be obtained

Embodiment 1

[0043] The invention discloses a method for cutting and manufacturing a liquid crystal display panel, comprising:

[0044] a. Disassemble and separate the LCD panel:

[0045] Disassemble the LCD screen panel from the LCD display;

[0046] b. Paste protective film: Paste a layer of plastic protective film on the polarizers on both sides of the LCD panel;

[0047] c. Positioning: According to the requirements of the cut size, plan the edge position of the LCD panel along the cutting direction, and remove the polarizer with the protective film to be cut off, and obtain the required chemical thinning on both sides of the LCD panel Protected and non-protected areas;

[0048] d. Thinning: Put the non-protected area of ​​the LCD panel obtained in step c into the chemical thinning solution, adjust the degree of thinning by controlling the length of time, and obtain a cut area with a thickness of 0.1-0.2mm, take out the LCD panel and rinse ,drying;

[0049] e. Fragmentation: Use a ...

Embodiment 2

[0052] As a preferred embodiment of the present invention, on the basis of Example 1, refer to the description attached figure 2 , after step e, there are: f, edging: place the LCD panel on the glass edging machine for positioning, determine the diamond grinding tool's walking route; use the diamond grinding wheel to grind the broken section, and the diamond grinding tool will start from the cutting edge Grinding the thickness area of ​​0.1-0.2mm after the LCD panel is thinned in the longitudinal direction. In the d step, refer to the attached figure 1 , the temperature of the chemical thinning liquid is maintained at 50 degrees Celsius, and the chemical thinning liquid is stirred by bubbling.

Embodiment 3

[0054] As the best implementation mode of the present invention, on the basis of embodiment 2, refer to the attached description image 3 , after the f step there is:

[0055] g. Film edge sealing: Use epoxy resin to seal the edge-grinding section of the fractured part of the LCD panel, and seal the edge with a metal film.

[0056] h. Connecting and forming, putting the edge-sealing LCD panel into a matching module to obtain an active matrix liquid crystal display with a special aspect ratio.

[0057] One side or two adjacent sides of the display are cutting edges, and sealing glue is encapsulated on the cutting edges. The sealing glue is in contact with the upper polarizer, the upper glass substrate, the liquid crystal material, the lower glass substrate and the lower polarizer of the display respectively.

Abstract

The invention discloses a manufacture method for cutting a liquid crystal display panel. A mode of chemical thinning liquid thinning glass is used for thinning a cutting frame of the liquid crystal display panel, a diamond grinding head is used for reconditioning a cutting plane, the reconditioned section is blocked by an epoxy resin, and edge sealing is performed by a metal film. The section cutby the method has the advantages of smooth flat, no stress and difficult cracking, and is capable of manufacturing the panels with any section shapes, wherein the thickness of the edge sealing glue-line is less than 0.2mm, thereby an ultra-narrow seam spliced screen with the width of seam-line of less than 1mm can be manufactured.

Description

technical field [0001] The invention relates to a cutting and manufacturing method of a liquid crystal display panel, in particular to a cutting and manufacturing method for transforming a liquid crystal screen of a standard size into a liquid crystal screen of a non-standard size. Background technique [0002] The LCD panel generally adopts a matrix scanning method, which determines its display area to be a rectangle. The aspect ratio of the screen size of mass-produced LCD panels is only 4: 3, 16: 9, 16: 10 and other standard specifications. [0003] For the display of medical equipment, radar indication, polar coordinate display, high-resolution electronic map and display, it is often necessary to use some special-shaped liquid crystal displays. Existing finished liquid crystal panels have relatively wide borders and cannot be used as ultra-narrow bezel LCD splicing screens. [0004] It is an important subject in this technical field to further process and transform pan...
