This invention provides a display panel and a fabricating method thereof. Wherein the display panel defines a display area and an edge area. The display panel includes a substrate, a gate layer, a gate insulating layer, a thin film encapsulation layer, and a polyimide layer. By disposing a buffer tank on the gate insulating layer, the flow rate of the polyimide solution printed through inkjet printing in the edge region is reduced when the polyimide layer is forming, thereby causing it to solidify to form the polyimide layer before flowing over a retaining wall, and preventing sealant contamination and peeling.

Abstract

A thin film transistor (TFT) and a method of manufacturing same are provided. A photoresist layer is dry-etched to form a tunnel before an active layer is formed, wherein a bottom of the tunnel is a copper trace layer. After that, two edges of the photoresist layer are aligned with two edges of the copper trace layer. Therefore, the photoresist layer won't protrude over an amorphous silicon layer to block the etching gas from etching the amorphous silicon layer. As a result, an aperture ratio of the TFT is increased, and quality of the TFT is improved. By forming an oxidation protective layer on the tunnel, the copper trace layer is prevented from being reacted with the etching gas to form a compound. Therefore, metals or compounds on the tunnel can be completely etched, and quality of the TFT is further improved.

Abstract

A TFT substrate and a manufacturing method thereof are provided. In the manufacturing method, a metal oxide semiconductor layer is irradiated with UV light by using a gate as a shielding layer, such that a portion of the metal oxide semiconductor layer irradiated by the UV light is conductorized to form a source, a drain, and a pixel electrode, and a portion of the metal oxide semiconductor layer shielded by the gate still retains semiconductor properties to form a semiconductor channel. The invention achieves the alignment of the source and the drain with the gate by processes of self-alignment of the gate and conductorization of the metal oxide semiconductor layer, and can effectively control an overlapping region of the source and drain and the gate. Thereby, the parasitic capacitance is reduced, and the display quality is improved. Also, the manufacturing method is simple, and the production efficiency is improved.

Abstract

The invention provides a manufacturing method of the TFT array substrate. Compared to existing 4M process, the invention changes the structural design of the semi-transmissive mask for the photoresist layer for patterning the source/drain metal layer and the semiconductor layer. The edge forms a reduced thickness edge portion, so that the edge of the photoresist layer is thinned, and thereby the width of the photoresist layer is easily reduced in subsequent processes, and the semiconductor layer at the edge of the metal wire structure is easily etched during dry etching, reducing the tailing problem of the active layer at edges of source/drain to achieve finer metal wire structure, and improve optical stability, electrical performance, aperture ratio, reliability, power consumption, and the overall performance of the TFT array substrate. The residual problem of amorphous and heavily doped silicon on source/drain edge in original process is solved or reduced.

Step S3 conducts white balance to the mask-joint area and non-mask-joint area using the first and second white balance driving tables, respectively. By applying different white balance driving tables to the mask-joint area and the non-mask-joint area, the white balance effect is improved, and the display quality of the LCD panel is enhanced.

Abstract

The present invention teaches a CF substrate, its manufacturing method, and a WOLED display device. The CF substrate includes a substrate, a pixel definition layer, and multiple filter patterns. The pixel definition layer has multiple openings, each corresponding to a sub-pixel area of the substrate. Each filter pattern is disposed on the substrate inside an opening of the pixel definition layer, and includes a quantum dot layer and a filter layer sequentially formed on the substrate. The CF substrate requires a single lithographic process to form the openings. The quantum dot layers and filter layers of the filter patterns are then formed by solution film formation in the openings, effectively simplifying the manufacturing process and enhancing the production efficiency. Applying the CF substrate to a WOLED display device also enhances the lighting efficiency, color gamut, and product quality of the WOLED display device.

Abstract

The invention provides an OLED display panel and manufacturing method thereof. The manufacturing method of OLED display panel of the invention forms a first scattering layer on the thin film encapsulation layer, a quantum dot layer on the first scattering layer, and a second scattering layer on the quantum dot layer. The first scattering layer extracts light from the OLED device, so that the light totally reflected by OLED device through thin film encapsulation layer is emitted as much as possible; the light extracted by the first scattering layer reaches the quantum dot layer. The quantum dots are excited to perform light color matching to emit light of desired color. Since the light excited by quantum dot layer is dispersed, the second scattering layer extracts the light excited by the quantum dot layer in an orderly manner, so that the OLED display panel emits light uniformly, thereby improving luminous efficiency.

Abstract

The present invention teaches a method for removing backlight mura. The method divides backlight into partitions, and divides each partition into units. The method then selects one of the partitions as a reference partition and selects the compensation values of the reference partition from all partitions. The method further calculates brightness difference values for all partitions other than the reference partition relative to the brightness of the reference partition. Finally, the method conduct brightness compensation to the other partitions based on the reference partition's compensation values, and the brightness difference values of the other partitions. The method may not only effectively eliminate backlight mura, but also allow the direct-lit backlight module to be thinner or of lower cost, and significant reduce storage requirement and logic resource.

Abstract

Disclosed are a thin-film transistor and a manufacturing method therefor. The manufacturing method comprises forming a gate electrode layer, an insulating layer, an amorphous silicon layer, a metal layer, a copper conductor layer and a photoresist layer on a base substrate. Before the manufacturing of an active layer, dry etching is carried out on the photoresist layer to form a channel with the copper conductor layer at the bottom, and at the same time, an edge of the photoresist layer is cut so as to align with an edge of the metal layer to prevent the photoresist layer from hindering the etching of the active layer by means of etching gas, thus improving the aperture ratio and the yield of the thin-film transistor. An oxidation protection layer is formed at the channel to prevent the copper conductor layer from reacting with the etching gas to form a compound, such that a clean channel can be subsequently obtained, improving the yield of the thin-film transistor.
