Description

1271553 V. INSTRUCTION DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a method of manufacturing a color filter (Color Fiiter; CF) for a liquid crystal display panel, and more particularly to manufacturing color using an inkjet technique. The method of the filter. [Prior Art] The reason why the liquid crystal display panel can be colored is mainly from a color filter. The liquid crystal display panel transmits a driving chip (Integrated Circuit;

The voltage change of I C) causes the liquid crystal molecules to stand or twist, forming a gate to select whether the backlight light penetrates or not, thereby generating a picture. However, there is only a difference in the degree of light transmission, and the color produced is only black and white. If color is to be formed, it needs to be combined with three kinds of light sources of red (R), green (G), and blue (B). The color filters of the red, green and blue color layers become the key components of the liquid crystal display panel.

Color filters typically require high color purity, high transparency, high contrast, and low reflection, and are highly stable against heat, light, and chemicals. There are four methods for coating color layers of color filters, namely Dyeing method, Pigment Dispersion method, Electro-Deposition (ED) method, and Printing (Printing). )law. However, the above method requires not only complicated processes and expensive equipment, but also limitations on the size of color filters. In addition, as the process and size increase, the yield will be reduced, thus wasting a lot of material and increasing production costs. In order to solve the above problems, ink-injection (Ink-Jet) technology has recently been developed to save the consumption of negative-type light groups and to reduce the exposure and development steps.喷1271553 V. Invention description (2) One-one "~------- ί, ^^ technology% wins with small equipment, reduced process time and ink consumption, and has developed in recent years Drop-On-Demand sprays, you can replace some of the cattle conductors to save more material and cost. The ink jet head is used to spray the solution 4, because the ink droplet size is extremely small, = ϊ set... must be matched with precise positioning control. Translucent red, green, blue: color: " and ^ ff film system black matrix, color control color layer sequentially added to the fixed position of the ^ π ^, 1 乍 color filter Need to have accurate alignment technology and a good match. The alignment technology is generally divided into two parts. Firstly, the image alignment analysis is performed by using, for example, an electric-p-component (Charge_c〇upled Device; ccH ink head and the alignment mark on the soil plate), and the current alignment is known. Accurate situation. Then, with the other part of the platform that can be accurately moved, the direction of the inkjet head, the gamma direction and the yaw angle of the two directions are controlled to achieve an accurate pair between the inkjet head and the substrate. As for the alignment mark, it can be set in the display area of the black matrix or the non-display area outside the display area, depending on the requirements. Please refer to FIG. 1 , which is a cross-sectional view showing a conventional inkjet device. The ink jet device can be disclosed, for example, in U.S. Patent No. 6,244, 712. The ink jet device 100 is designed to be a positioning platform (P〇siti〇n Stage) 1 0 1 'Using a spray The ink head 1 〇 3 moves in a manner of performing ink ejection of the color resist j 〇 5. When the ink jet head performs the pre-ejection alignment, it is indirectly defined according to the side of the substrate i 〇 7 parallel to the side of the positioning stage 101. In the X direction and the Y direction between the ink head 1〇3 and the substrate 1〇7, First adjusting the front substrate and the discharge 〇7 i

1271553 V. Description of invention (3) The distance between the ink heads 1 0 3 in the Z direction, and then the inkjet head 1 〇 3 with a sensor (Sensor) 10 9 respectively observe the positioning platform 1 〇 1 in the X direction, γ The direction of the six degrees of freedom (Freedom) of the direction and the skew angle is used to check the relative position of the ink jet head 103 and the substrate 107.

Referring to Fig. 2, there is shown a plan view of a conventional color filter which can be used, for example, in the inner valley disclosed in U.S. Patent No. 6, 丨 4 3, 4500.

In the above process of fabricating a color filter by inkjet technology, as shown in FIG. 1 on the one hand, the conventional technology is directed to the solution of the alignment of the inkjet head, and the inkjet head 1 is indirectly defined only by the positioning platform 101. The relationship between 〇3 and the substrate 1 〇γ, iron without directly defining the relationship between the ink jet head 103 and the substrate 1〇7, inevitably causes errors. On the other hand, as shown in Fig. 2, in the prior art, when the shape of the opening of the element is changed as the alignment mark 2 0 7 , the alignment mark 2 〇 7 is arranged in the display area 20 of the M color matrix 2 0 3 . Therefore, the alignment mark 2〇7 may affect the visible size of the display area 20 9 , and even produce a product with a bad/visual effect; and the shape is different from the alignment of the pixel opening 2〇5. Mark 2〇7 may cause difficulty in inkjet. In addition, the alignment problem occurs not only in the process of the color filter, but also in the subsequent recording process of the liquid crystal display panel. Current color = process of liquid crystal display (color TFT ~ LCD)',
