The gate driving circuit includes a plurality of driving units connected in cascade. Each driving unit includes: N shift register units; and a mode control circuit connected to the N shift register units, wherein the mode control circuit is configured to receive a control signal for the driving unit, and connect the N shift register units in one of a plurality of resolution modes under the control of the control signal.

Abstract: Embodiments of the present application provide a screen body support device, including: a fixing bracket; a movable bracket being rotatably connected with the fixing bracket, in which the movable bracket and the fixing bracket are provided in a non-display area of a flexible display screen; and a driving component being fixedly connected with the movable bracket, in which the driving component is configured to drive the movable bracket to swing in two opposite directions with respect to the fixing bracket, so that the flexible display screen is bent in two opposite directions respectively.

Abstract: A support apparatus for a flexible screen, a foldable display module and a display device. The support apparatus for the flexible screen includes a support portion and a driving assembly. The support portion includes a first support portion and a second support portion connected with the first support portion. The driving assembly includes a rotary shaft assembly and a linkage assembly connected with the rotary shaft assembly. The rotary shaft assembly includes a plurality of rotary shafts arranged in parallel. The second support portion is slidably provided on the rotary shaft assembly and can be bent or unfolded together with the rotary shaft assembly. When the rotary shaft assembly is bent, the first support portion is driven by the linkage assembly to move away from or close to the rotary shaft assembly.

Abstract: A LED driving system for driving a LED matrix. The LED driving system includes an interconnection structure having a first surface and a second surface opposite to the first surface and a plurality of driver dies/chips attached to the first surface of the interconnection structure. The LED matrix is divided into a plurality of sub LED matrix sections that are attached to the second surface of the interconnection structure. The interconnection structure is configured to electrically couple each one of the plurality of sub LED matrix sections to a corresponding one driver die/chip in the plurality of driver dies/chips.

Abstract: Integrated circuit (“IC”) unit and a wafer for fabricating IC units. The wafer has a first surface and a second surface opposite to the first surface. A redistribution metal layer may be formed on the first surface and may be patterned to have a redistribution metal layer pattern. A backside metal layer may be formed on the second surface and patterned to have a backside metal layer pattern so that the backside metal layer may be adapted to generate a backside stress on the wafer to at least partially offset a front side stress generated by the redistribution metal layer on the wafer.

Abstract: A particle for treatment and repair of soil contamination is mainly composed of potassium ferrate and an inorganic cementitious material. The inorganic cementitious material is a powdery air-hardening or hydraulicity inorganic cementitious material. The potassium ferrate and the inorganic cementitious material are mixed according to the mass fraction of 1:5-50. After mixing is carried out, the particle with the particle diameter ranging from 2 mm to 5 mm is formed by means of vibration of a vibration screen, the particle is wrapped by a water-soluble film, and the water-soluble film is heated to be shrunk and then is closely attached to the outer surface of the particle. Also disclosed is a method for repairing soil by using the particle. When the particle is mixed with an ozone water solution is adopted.
