Embodiment Construction

[0082] The present invention will be further described below in conjunction with accompanying drawing.

[0083] Such as figure 2 In the shown embodiment, the coating device for obtaining color filters includes a coating platform 1 and a coating mechanism 2;

[0084] The coating device for obtaining color filters also includes an initial elevating and extending platform 3 and an end elevating and extending platform 4;

[0085] The initial lifting extension platform 3 is set on one side of the coating platform 1 in the coating starting direction;

[0086] The lifting and extending platform 4 at the end section is arranged on one side of the coating platform 1 in the coating end direction.

[0087] On the basis of the original coating platform 1, the present invention adds an initial lifting and extending platform 3 and an ending lifting and extending platform 4, so that the film layer coated in the acceleration stage and the film layer coated in the deceleration stage produce...

Abstract

Provided are a color filter, a coating device for obtaining color filters, and an obtaining method, relating to the color filter technical field. The thickness uniformity of a color filter color layer is less than 1.2%. The coating device for obtaining color filters comprises a coating platform and a coating mechanism, and also comprises an initial segment elevating extension platform and an end segment elevating extension platform. The obtaining method comprises: cleaning and loading a glass matrix; adjusting the initial segment elevating extension platform and the end segment elevating extension platform, and maintaining surfaces flush; starting the coating mechanism; withdrawing the glass matrix which has the surface coated; and cleaning again. The coating device is provided with the initial segment elevating extension platform and the end segment elevating extension platform, allowing the film layers on the glass matrix to be all film layers which are rapidly completed by the coating mechanism in a stable operation stage, and improving glass matrix film thickness uniformity; the coating mechanism and a chip packaging device can both operate in a stable state, the service life of the device can be prolonged, and the cost can be reduced.

Description

technical field [0001] The present invention relates to the technical field of color filters, in particular, to a color filter and a coating device and method for obtaining it. Background technique [0002] Color filter (Color filter) is an optical filter that expresses color, it can precisely select the small range of light waves to be passed, and reflect off other unwanted wave bands. Color filters are usually installed in front of the light source so that the human eye can receive saturated light of a certain color. There are infrared filters infrared, green, blue and so on. Compared with UV filter and VD filter, it is a general term for all colored filters. Such as contrast filter, color separation filter, LB filter, etc. [0003] Color filter applications include contrast enhancement of monochrome displays through the color selection passband and the maximum output power of the display. Broadband filters are used to improve the contrast and performance of optical sc...
