LCD structure and manufacturing method thereof

Abstract

The invention discloses an LCD structure which comprises an upper polarizer, upper glass, lower glass, a lower polarizer and a color film. The bottom of the upper polarizer is attached to the top of the upper glass, the bottom of the upper glass is attached to the top of the lower glass, the bottom of the lower glass is attached to the top of the lower polarizer, and the color film is attached to the bottom of the lower polarizer; the color film comprises a release layer, a glue layer, a color layer and a protection layer, the release layer is attached to the top of the color layer through the glue layer, the bottom of the color layer is attached to the protection layer, and the color area painted with color patterns is arranged in the middle of the color layer. The invention further provides a manufacturing method of the LCD structure. The LCD structure and the manufacturing method thereof have the advantages that the productivity is improved by 3-6 times, the labor saved by 2-3 persons, the material cost is reduced by 20-50%; environmental pollution is greatly reduced, and the LCD structure is more environmentally friendly; the product rework rate is decreased by 5% or above, and the rework cost is greatly lowered; the LCD structure is suitable for all products needing to display color pen sections and patterns on a black and white LCD.

Description

technical field [0001] The invention relates to the technical field of LCD liquid crystal display, in particular to an LCD structure and a manufacturing method thereof. Background technique [0002] Black and white LCD can only display black or white fonts. If you want to display part of the pen segment or pattern in color, such as red, yellow, blue, green, etc., you need to add other colors to the pen segment display area to achieve black and white LCD color. show. At present, the conventional method is: add color ink to the screen printing screen frame, use the screen frame to screen-print the color ink on the area of ​​the LCD surface where the color pen segment needs to be displayed, dry the ink and then place the patch, and drive the LCD to display the area Strokes or patterns are displayed in color. However, this conventional approach has the following disadvantages: [0003] (1) Waste of manpower and man-hours: Four people are required to complete this process. Amo...

Problems solved by technology

[0003] (1) Waste of manpower and man-hours: Four people are required to complete this process. Among them, one person adjusts the screen printing glass, one person checks the quality of the silk screen printing, one person picks up the dried glass, and one person reworks and wipes off the screen printing defective products (use acetone to wipe off the screen printing ink, re-screen);

[0004] (2) Large environmental pollution: This process is generally operated in a closed workshop. Since inks, thinners, curing agents, and net washing water are all chemicals, they have a strong smell and a large environmental pollution. harmful;

[0005] (3) The output efficiency and yield rate are low, the silk screen rework rate is high, and the overall cost is high
