Problems solved by technology

[0003] In the existing transflective liquid crystal display screen, the transmittance and reflectance are mutually restrained, the transmittance is high and the reflectance is low, otherwise the reflectance is high and the transmittance is low; at the same time, due to the difference in the optical path of the reflected light and the transmitted light, resulting in reflection The display contrast in this mode is reduced; at the same time, the existing transflective liquid crystal display is formed by the alignment process, and the preparation process is also cumbersome, and there are also disadvantages of light leakage caused by alignment deviation.

Embodiment 1

[0026] This embodiment provides a display substrate. The display substrate is integrated with a colored color resist layer. Compared with the prior art in which a color filter substrate and an array substrate are combined to form a display panel, the combination process can be saved, and the pixels can be ensured. The accuracy of alignment avoids the problem of light leakage caused by alignment deviation; at the same time, the display substrate also adopts RGBW four-color pixel display mode, which can better ensure the brightness of pixel display.

[0027] The display substrate includes a plurality of pixel regions and thin film transistors arranged in the pixel regions, for example, thin film transistors arranged in border regions of adjacent pixel regions, such as figure 1 As shown, each pixel area is divided into a transmissive area 1 and a reflective area 2, and a protective layer 16 is arranged above the thin film transistor; meanwhile, refer to figure 2 The protection l...

Embodiment 2

[0036] This embodiment also provides a method for preparing a display substrate corresponding to the display substrate in Embodiment 1. For the display substrate, the protective layer above the thin film transistor and the optical path difference between the reflection area and the transmission area are equal The protrusions are formed at the same time, which simplifies the preparation of the display substrate. Since the preparation method of the display substrate can realize the preparation of the transflective display substrate with fewer process steps, the production and use costs are saved, and the prepared display substrate has good display effect.

Embodiment 3

[0050] This embodiment provides a display device, including the display substrate in Embodiment 1 and a common electrode layer disposed opposite to the display substrate.

[0051] In the display device, the sum of the thicknesses of the protrusions of the protection layer and the reflective layer is half of the distance between the surface of the display substrate corresponding to the transmissive area and the surface opposite to the common electrode layer.

[0052] The display device may be any product or component with a display function such as a liquid crystal panel, electronic paper, a mobile phone, a tablet computer, a television, a display device, a notebook computer, a digital photo frame, a navigator, and the like.

[0053] The display device has better color and brightness, and has good display effect.

Abstract

The invention belongs to the technical field of display, and particularly relates to a display substrate, a manufacturing method for the same and a display device. The display substrate comprises a plurality of pixel areas and thin film transistors arranged in the boundary areas of the adjacent pixel areas, wherein each pixel area is divided into a transmission area and a reflection area; protective layers are arranged above the thin film transistors; lugs are arranged in the areas, corresponding to the reflection areas, of the protective layers, and through holes are formed in the areas, corresponding to the thin film transistors, of the protective layers. According to the display substrate, light leakage can be effectively avoided, and higher color uniformity and display brightness are further achieved; moreover, by the manufacturing method for the display substrate, process steps can be simplified, and the production cost can be lowered.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display substrate, a preparation method thereof, and a display device. Background technique [0002] Currently, a liquid crystal display (LCD for short) has become a mainstream product in the market due to its excellent performance and mature technology. Liquid crystal display devices are classified according to the type of light source, and can be classified into transmissive, reflective and transflective. Among them, the transflective liquid crystal display device combines the advantages of the reflective liquid crystal display device and the transmissive liquid crystal display device, and is suitable for both indoor use and outdoor use, so it has been widely used in portable mobile electronic devices. Applications. [0003] In the existing transflective liquid crystal display screen, the transmittance and reflectance are mutually restrained, the transmittance ...
