Color film substrate and preparation method thereof and display panel

Abstract

The invention provides a color film substrate and a preparation method thereof and a display panel. The color film substrate comprises a substrate, at least one spacer and at least two elastic supportparts; the spacer is arranged on one side of the substrate, and a first electrode is arranged on the outer surface; the elastic support parts and the spacer are arranged on the same side of the substrate; at least two elastic support parts are arranged on the outer side of each spacer; the at least two elastic support parts are uniformly arranged along the periphery of the spacer at intervals; and the height of each elastic support part is greater than the sum of the height of the spacer and the thickness of the first electrode. The inventor finds that after the color film substrate is laminated with an array substrate, the matching effect between the first electrode and the array substrate can be relatively high; under the effect of the elastic support parts, the first electrode or a negative electrode is barely damaged; and the elastic support parts are arranged on the outer side of each spacer, so that damage to the first electrode or the negative electrode by any one spacer causedby pressing can be avoided effectively.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a color filter substrate, a preparation method thereof, and a display panel. Background technique [0002] In an OLED display panel, when the external circuit is too long or too thin, a serious voltage gradient will be caused on the external circuit, so that the voltage actually falling on the OLED component is low. Since the OLED component is driven by current, the above external power The consumption will lead to a decrease in the luminous intensity of the display panel. Currently, an auxiliary electrode is usually added to reduce the voltage gradient to increase the luminous efficiency of the display panel and increase the driving voltage of the OLED component. [0003] At present, the usual method of adding auxiliary electrodes is to prepare spacers on the color filter substrate, form the first electrode on the surface of the spacer, and make the first electrode co...

Problems solved by technology

However, due to the existence of the filling layer, it is difficult for the spacer material to achieve high elasticity. Therefore, excessive force during the process will cause crushing and defects, and too little force will cause poor or inaccessible problems, which will easily cause the display panel. There are different degrees of unevenness (mura) in the display screen
