  • Patent number: 11411101
    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.

  • Patent number: 11239447
    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.

  • Patent number: 11233138
    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.
