Problems solved by technology

However, the inkjet method used today is slow and bulky, and the printable format is small, which is not suitable for the large-scale requirements of color filters.
[0010] The manufacturing methods of the above several main color filters cannot take into account the requirements of simple and convenient process, high precision and low cost. The color filter manufacturers are working on improving the existing methods to obtain a simple and convenient method. Low-cost and high-performance color filter manufacturing method

Embodiment 1

[0051] 1. Make black, red R, green G and blue B thermal transfer films.

[0052] Its production process is as follows:

[0053] (1) See attached figure 1 As shown, the release layer 12 is coated on the PET plastic substrate 11, and the thickness of the PET plastic substrate is 10um-150um;

[0054] (2) Coating black resin on the surface of the release layer, or coating resin permeated with colored dyes on the release layer, the colors of the dyes are respectively red, green and blue to form a color layer (13). The chromaticity of the color layer meets the color filter standard, and the thickness meets the thickness requirements of each color pixel of the color filter. The thickness of each color layer is <3um.

[0055] (3) Coating a layer of adhesive layer 14 on the color layer, such as transparent hot melt adhesive, the specific material should be selected according to the adhesion requirements of the material of the color filter substrate. According to the above steps, a ...

Embodiment 2

[0063] Embodiment two: see attached Figure 8 Shown, a kind of planar type color filter manufacturing device comprises by DPSSL laser light source 51 with TTL signal interface, iris diaphragm 52, spot shaper 53, quartz lens 55 (objective lens), reflecting mirror 56 and quartz lens 57 together form a 4F system, a beam splitting device 58 (the example in this figure is a beam splitting into a rectangular light spot with uniform light intensity in one-dimensional and three-beam spots), a working platform 591 , and a control system 510 .

Embodiment 3

[0064] Embodiment three: see attached Figure 9 Shown, a kind of planar type color filter manufacturing device comprises by DPSSL laser light source 51 with TTL signal interface, iris diaphragm 52, spot shaper 53, quartz lens 55 (objective lens), reflecting mirror 56 and quartz lens 57 together form a 4F system, a beam splitter 58 (the example in this figure shows that the beam is split into a rectangular light spot with uniform light intensity in one-dimensional and three-beam spots), a drum-type workbench 592 , and a control system 510 .

[0065] In this embodiment, the energy distribution of the light beam emitted by the laser is 541, which is Gaussian. After the beam is shaped, the energy distribution of the beam is 542, which is rectangular, and the light intensity is uniform.

[0066] In this embodiment, the beam splitting element can be a beam splitting grating or a beam shaping device (LCD or DMD), which divides the single beam emitted by the laser into multiple one-di...

Abstract

The invention discloses a production method and a device for a colored filter. The production method is as follows: four heat transfer films with color layers are respectively obtained; one heat transfer film is adhered on the surface of a substrate of a colored filter, a rectangular laser beam is adopted to instantaneously irradiate the corresponding position of the heat transfer film according to the arrangement positions of picture elements, so that the color layer of the heat transfer film is transferred onto the surface of the substrate, the irradiation positions are adjusted, and the steps are repeated to realize the transfer of all the picture element units with the same color; the heat transfer film is replaced, the steps are repeated so that the four colors are transferred, thereby obtaining the needed colored filter. During the whole process of the invention, the relative position of the substrate does not change, which solves the problem that the prior method needs a high-precision contraposition, and can control the size of picture element patterns through the size of light spots of the laser; at the same time, the method is applicable to the production of flexible colored filters.

Description

technical field [0001] The invention relates to a method for manufacturing components of a liquid crystal flat panel display, in particular to a method for manufacturing a color filter for a color liquid crystal flat panel display, and a manufacturing device using the method. Background technique [0002] Color filter is a key component of liquid crystal display (Liquid Crystal Display) colorization. Liquid crystal flat panel display is a non-active light-emitting component, and its color display must provide a light source through an internal backlight module (transmissive LCD) or external ambient incident light (reflective or semi-transmissive LCD), with a driver integrated circuit ( Drive IC) and liquid crystal (Liquid Crystal) control to form a grayscale display (Gray Scale), and then pass through the red (R), green (G), blue (B) color layers of the color filter to provide hue (Chromacity), forming Color display screen. [0003] A color filter is usually composed of a ...
