Abstract: A display panel includes a first substrate and a second substrate. A thin film transistor is disposed on the first substrate. The display panel has a non-display area; the non-display area includes a first metal layer, a frequency signal line formed by a second metal layer and located on the first metal layer, a via (contact hole), and a conducting electrode electrically connecting the first and a second metal layers together. At least a part of the conducting electrode is located in the via. A photo spacer is located in the via, for separating the first substrate and the second substrate. The photo spacer completely covers the conducting electrode. The photo spacer is made of a dielectric material.

Abstract: Disclosed is a method and system of gesture recognition in a touch display device, which is able to predetermine gesture inputs possibly to be made by a user prior to the completion of the user's touch input, and enable a display unit to display all possible similar gesture inputs so as to provide an instruction (or navigation guidance) for the user. Thus, when using a large-sized touch display device, the user does not have to perform touch operations widely throughout the screen of the display device, because the system can recognize the similar gesture inputs in advance, which renders it easier for the user to operate on the touch display device, thereby obtaining a better user experience.

Abstract: A gate driver on array (GOA) and a liquid crystal display are disclosed. The GOA circuit includes a plurality of cascaded GOA units and a plurality of pull-down maintaining circuits. The cascaded GOA units are configured for respectively outputting gate driving signals of first level signals to charge corresponding horizontal scanning lines within a display area when being controlled by a plurality of clock signals. Each of the pull-down maintaining circuits corresponds to at least two cascaded GOA units, and each of the pull-down maintaining circuits is configured for maintaining the corresponding at least two cascaded GOA units to output second level signals as the gate driving signals during a non-operation period. As described above, the disclosure can reduce the amount of the pull-down maintaining circuits, so as to decrease the width of the layout of the GOA circuit to meet the need to design a narrow-frame liquid crystal display.

Abstract: Provided is a touch control display penal and a touch control circuit thereof. A test signal line and a touch control signal line are redesigned without any change in a conventional pixel structure, such that the touch control circuit as formed has both a test function and a touch detection function. Therefore, not only the manufacturing costs of an in-cell touch display device are effectively reduced, but the manufacturing procedure is simplified, and the yield rate of the touch display panel is improved as well.

Abstract: A method for manufacturing a LTPS array substrate includes: forming a source electrode and a drain electrode on a substrate, forming a poly-silicon layer in a first region and a second region of the substrate including the source electrode and the drain electrode, such that the poly-silicon layer of the first region has a thickness greater than that of the second region and the poly-silicon layer of the first region partially covers the source electrode and the drain electrode; passivating a surface of the poly-silicon layer in order to turn a part of the poly-silicon layer of the second region and the first region that is adjacent to the surface into an insulating layer; and forming a gate electrode on the insulating layer between the source electrode and the drain electrode. The LTPS technical process is simple and can reduce the producing costs.

Abstract: Provided are a pixel driving structure, in which the nth column of TFTs (T) are arranged at positions where the nth column of sub pixels (P) is close to the nth data line (D(n)); in the nth column of sub pixels (P), four sub pixels (P) or two sub pixels (P), which are adjacent vertically in the upper and the lower are set to be a pixel group (PG), and the nth data line (D(n)) sets a signal period to define polarities of respective sub pixels (P) in the pixel group (PG) to make polarity inversion occur at a edge of the two adjacent pixel groups (PG) in the upper and the lower, and polarities of two adjacent columns of sub pixels (P) are opposite to achieve display effect similar to a dot inversion. The pixel aperture regions can be neatly aligned to prevent the color washout.

Abstract: An LTPS array substrate and a method for producing the same are proposed. The method includes: forming an insulating layer, a semiconductor layer, and a first positive photoresist layer on the substrate one by one; exposing one side of the substrate on the opposite side of the gate for forming a polycrystalline silicon layer; forming a source and a drain of the TFT on the polycrystalline silicon layer; forming a pixel electrode on the insulating layer and part of the source; forming a plain passivation layer on a source-drain electrode layer; forming a transparent electrode layer on the plain passivation layer so that the transparent electrode layer is connected to the gate, the source, and the drain via the contact hole. The use of masks in types and numbers in the LTPS technology can be reduced. Thus, both of the processes and the production costs are reduced.
