Abstract: A manufacturing method for TFT array substrate and TFT array substrate are disclosed. After depositing an electrode material layer and a metal material layer on the gate insulation layer and the active layer in sequence after the active layer above the gate electrode is formed. A photoresist pattern is formed on the metal material layer. The photoresist pattern includes a first and second photoresist blocks with different thicknesses. The metal material layer and the electrode material layer are etched using the photoresist pattern to form a contact electrode and pixel electrodes connected with two ends of the active layer and the source/drain electrodes on the contact electrode. The process is simple and can effectively reduce the contact resistance between the source/drain and the active layer and improve the quality of the product.

Abstract: The present invention teaches a direct-lit backlight module and a related manufacturing method. The direct-lit backlight module includes a driver substrate, a reflection layer on the driver substrate, multiple mini-LEDs arranged in an array on the reflection layer, multiple reflection bumps on the reflection layer among the mini-LEDs, and an optical film set on the reflection layer, the mini-LEDs, and the reflection bumps. The mini-LEDs are electrically connected to the driver substrate. The reflection bumps jointly form a mesh dot structure. When light passes through the mesh dot structure, the light is scattered by the mesh dot structure to various directions, thereby enhancing the lighting efficiency of the direct-lit backlight module.
