Abstract: The present invention provides a manufacture method of a N type thin film transistor. In the manufacture process, the chemical solution is employed to etch the channel region of the N type thin film transistor to raise a surface roughness of the low temperature polysilicon in the channel region of the N type thin film transistor, and thus to raise the surface defect density of the low temperature polysilicon in the channel region of the N type thin film transistor. Then, the threshold voltage of the manufactured N type thin film transistor moves toward the positive direction to ensure that the manufactured N type thin film transistor can be closed in time under the low voltage. The production efficiency is high and the production cost is low.

Abstract: The present invention provides a manufacture method of a LTPS array substrate. By utilizing one halftone mask, the N type heavy doping, the channel doping of the first polysilicon layer of the NMOS region and the P type heavy doping of the second polysilicon layer of the PMOS region, the three processes which previously require three masks are integrated into one mask process, and two exposure processes are eliminated, which significantly raises the exposure capacity, and meanwhile saves the manufacture cost of two masks to effectively reduce the manufacture cost of the LTPS array substrate, and the manufactured LTPS array substrate possesses great electrical property.

Abstract: The present invention provides a LTPS display panel and a manufacture method thereof. In the LTPS display panel, the edge of the back matrix (12) comprises a convex part (104) capable of ensuring that the light emitted from the pixel unit (22) of the array substrate (20) only penetrates through the color resist block (131/132/133) corresponding to the pixel unit (22) in the color film substrate (10), and no light leakage happens between adjacent pixel units and thus, can reduce the large view angle color washout to improve the display quality of the LTPS display panel. In the manufacture method of the LTPS display panel, one halftone mask process is employed to form the black matrix (12), and the edge of the back matrix (12) comprises a convex part (104) which can better shade the light leakage between adjacent pixel units as watching in the large view angle.

Abstract: The present invention provides a manufacturing method of a color filter substrate, in which a layer of photoresist layer of a negative photoresist resin material is first formed on the color filter film layer; then, back side exposure is conducted on the photoresist layer from the underside of the backing plate so that a part of the photoresist layer that is adjacent to the backing plate gets cured for subsequently forming a planarization layer; afterwards, a mask is used to conduct front side exposure on the photoresist layer from the backing plate to form post spacers; and finally, the photoresist layer that has been subjected to exposure twice is subjected to development to remove a portion of the photoresist layer that has not been cured so as to form, simultaneously, a planarization layer and post spacers located on the planarization layer. This, when compared to an existing manufacturing method of a color filter substrate, can greatly simplify operation flow and thus greatly reduce investment on manufacturing line facility and lower down manufacturing costs of products and potential risks of unexpected problems occurring in the manufacturing process and shortening product manufacturing cycle.

Abstract: A gate driving circuit disposed on an array substrate and an LCD using the same are described. The gate driving circuit on the array substrate comprises a plurality of sequentially connected gate driving units. The gate driving circuit unit comprises an input module, a reset module, a latch module and a signal processing module. The signal processing module receives the current inverse stage-transmitting signal XQ(N), the low voltage signal, a second clock signal and a third clock signal to control on/off statuses of two transistors by the current stage-transmitting signal Q(N) so that the two transistors forms Nth gate signal G(N) and gate signal (N+1)th based on the second clock signal and the third clock signal. The present invention utilizes less clock signals and transistors, which is favorable to the narrower LCD's frame design and solves the problem of manufacturing process restriction of the LCD panel.
