    Abstract: A backlight module and a liquid crystal device (LCD) are disclosed. The backlight module includes a light guiding plate, a plastic frame adjacent to a lateral side of the light guiding plate, and a reflective sheet. The reflective sheet includes a first portion, a second portion, and a third portion. The first portion of the reflective sheet is arranged below a bottom of the light guiding plate and/or a bottom of the plastic frame, the second portion of the reflective sheet adheres to a lateral side of the plastic frame, and the lateral side faces away from the light guiding plate, and the third portion of the reflective sheet adheres to a top surface of the plastic frame. With such configuration, the reflective sheet may be stably fixed on the plastic frame to prevent the reflective sheet from being detached.

    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 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: A display panel and a liquid crystal display are disclosed. The display panel includes an upper polarizer, a lower polarizer, a first substrate and a second substrate disposed oppositely between the upper polarizer and the lower substrate, a liquid crystal layer disposed between the first substrate and the second substrate, a quantum dot layer disposed at a side of the second substrate which is far away from the liquid crystal layer, and a protection layer for protecting the quantum dot layer, disposed between the quantum dot layer and the lower polarizer. The quantum dot layer is disposed at a side of the second substrate far away from the liquid crystal layer, and the protection layer is disposed between the quantum dot layer and the lower polarizer. The protection layer is used for preventing the quantum dot layer from being oxidized. The color gamut of LCD can be increased.

    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.
