Problems solved by technology

[0004] The invention provides a preparation method of a color film substrate, a color film substrate and a liquid crystal display panel, which can reduce the impedance of an ITO conductive film, so as to solve the problem of the existing preparation method of a color film substrate, a color film substrate and a liquid crystal display panel. The impedance of the conductive film is too large, causing the delay of the HVA signal, which further affects the technical problem of the normal alignment of the liquid crystal

Embodiment Construction

[0028] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.

[0029] The present invention is aimed at the preparation method of the color filter substrate, the color filter substrate and the liquid crystal display panel. Due to the excessive impedance of the ITO conductive film, the HVA signal is delayed, which further affects the technical problem of the normal alignment of the liquid crystal. This embodiment can solve the probl...

Abstract

The invention provides a preparation method of a color film substrate. The preparation method comprises steps as follows: a glass substrate is provided, and an ITO film layer is formed on the surfaceof the glass substrate; and a silver nanoparticle film layer is deposited on the surface of the ITO film layer in an electrophoretic deposition manner, and a conductive film layer is obtained. The invention also provides a color film substrate prepared with the method and a liquid-crystal display panel. With the adoption of the preparation method, silver nanoparticles are deposited on the surfaceof the ITO film layer in the electrophoretic deposition manner, ITO impedance is reduced, resistance and capacitance delay effects are reduced, and further, liquid crystal alignment is more sufficient.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for preparing a color filter substrate, a color filter substrate and a liquid crystal display panel. Background technique [0002] At present, the HVA (High Vertical Alignment) alignment in TFT-LCD (thin film transistor-liquid crystal display panel) is a very important process, and its main function is to give the liquid crystal molecules in the TFT-LCD a pre-set The tilt angle allows the liquid crystal molecules to rotate faster when the display panel is working, so as to improve the response speed of the panel. The HVA alignment process must be powered on, the current is provided by the metal circuit board, passes through the array substrate, and is introduced into the ITO (Indium Tin Oxides, indium tin oxide) conductive film on the color filter substrate through the gold balls, and finally in the array substrate and the color filter substrate. There is a voltage dif...
