Embodiment Construction

[0068] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail with reference to the accompanying drawings.

[0069] Manufacturing method of asymmetric protrusions:

[0070] Figure 5A ~ Figure 5B It is a schematic flowchart of a method for manufacturing an asymmetric protrusion in a preferred embodiment of the present invention. Please refer to Figure 5A , firstly, a substrate 210 is provided. The substrate 210 can be a glass substrate, a quartz substrate, a plastic substrate, or other suitable substrates. After that, if Figure 5A A film layer 220 is shown formed on the substrate 210 . The method of forming the film layer 220 is, for example, spin coating method, printing method (Printing), chemical vapor deposition (Chemical Vapor Deposition, CVD) and so on. In addition, the material of the film layer 220 may be an organic photosensitive material, such as pho...

Abstract

The invention relates to a method for manufacturing an asymmetric convex object and pixel structure. Firstly, a substrate is provided; then, a film layer is formed on the substrate; later, a composite light shield is provided; the composite light shield comprises at least one light-transmitting area, a plurality of non-light-transmitting areas, and a plurality of semi-light-transmitting areas, wherein, each semi-light-transmitting area is located between two adjacent non-light-transmitting areas, moreover, each semi-light-transmitting area is also provided with at least one light shielding pattern which is arranged at random. Later, the composite light shield is used as a shield screen for patterning the film layer so as to form a plurality of asymmetric convex objects on the substrate. By using the composite light shield, the steps for manufacturing the asymmetric convex object can be reduced. In addition, a method for manufacturing the pixel structure of the asymmetric convex object is also provided.

Description

Technical field: [0001] The present invention relates to a bump and a method for manufacturing a pixel structure with the bump, and in particular to an asymmetric bump that can reduce the number of photomasks used and a bump with the asymmetric bump A method of manufacturing a pixel structure of an object. Background technique: [0002] The pixel structure of a Thin Film Transistor Liquid Crystal Display (TFT-LCD) can be classified into three types: transmissive, reflective and transflective. In the penetrating pixel structure, the pixel electrode of the pixel structure is made of transparent conductive material, and the backlight source is used to provide light. The light can pass through the transparent pixel electrode to provide the light source required for picture display. [0003] In the reflective pixel structure, the pixel electrode of the pixel structure is mainly made of a conductive material with the characteristic of reflecting light, so that the light incident...
