Abstract: A display device provided includes a display panel, a first backlight module, a second backlight module, a light sensor, and a viewing angle adjusting component. The first backlight module includes an optical element, and the viewing angle adjusting component is disposed corresponding to a display sensing area. When the optical element is in a fog state, the viewing angle adjusting component reduces an exit angle of backlight. When the optical element is in a transparent state, external light enters the light sensor through the viewing angle adjusting component and the first backlight module, which improves uniformity of backlight viewing angle.

Abstract: A display panel and a display device are provided. The display panel includes a display area including a transparent display area and an opaque display area surrounding the transparent display area. The display panel further includes a first substrate layer, a luminous layer, a liquid crystal layer, a first driving layer, and a second driving layer. The display panel is divided into the transparent display area and the opaque display area by combining an organic light-emitting diode technology and a liquid crystal display technology, such that the transparent display area can provide a light channel for a camera and can also display an image, thereby improving a screen-to-body ratio and realizing a real full-screen display.

Abstract: A backlight module and a display device, by disposing backlight concave sections on a light source lateral side of a back frame in the backlight module, the backlight concave sections and panel concave sections on a display panel correspond to one another. During assembling, part of sections of a flexible electric circuit board is bent to back of the backlight module through an edge of the panel concave section and the backlight concave sections to reduce a size of a bottom bezel of the display device, which improves the screen-to-body ratio of the display device.

Abstract: The present invention teaches a LTPS TFT substrate and its manufacturing method. The manufacturing method, after forming vias using the photoresist layer on the ILD layer and the gate insulation layer above the source/drain contact regions, and before peeling the photoresist layer, forms conductive layers in the vias by depositing conductive material in the vias. The source/drain electrodes contact the conductive layers in the vias and therefore are conducted to the source/drain contact regions, thereby effectively resolving the problem of contact impedance being too high between the source/drain electrodes and the source/drain contact regions from the existing re-etch LDD technique. Then, through the re-etch LDD technique, the present invention is able to omit a mask process without sacrificing product characteristics. In addition, the vias and the photoresist layer have undercut structure, preventing the deposited conductive material from affecting the photoresist layer's peeling and guaranteeing the photoresist layer's peeling efficiency.

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: A gate driving circuit and a display panel are disclosed. A pull-up control module and a pull-down module of each stage gate driving unit are connected to a first node. A thin film transistor in the pull-up control module and/or pull-down module that is connected to the first node is an oxide thin film transistor, such that a leakage current of the first node is reduced due to the advantage of the small off-state leakage current of the oxide thin film transistor. Therefore, the voltage level of the first node can remain stable during a pull-up stage and a touch suspension stage.
