Abstract: A liquid crystal display comprises a demultiplexer (Demux). The demultiplexer for the display comprises an integrated circuit unit and a logic unit electrically connected to the integrated circuit unit. The integrated circuit unit outputs three pulse signals including a first pulse signal, a second pulse signal, and a third pulse signal. The logic unit transforms the three pulse signals having different high and low voltage levels into at least four control signals.

Abstract: A Complementary Metal-Oxide-Semiconductor (CMOS) Gate Driver on Array (GOA) circuit includes a plurality of cascaded GOA units, where each of the GOA units comprises a forward-rearward control module, a signal-latch module, a signal-process module, and a signal-buffer module. A waveform of a scan-line driving signal outputted has two falling edges, to prevent un-uniformity of a liquid crystal panel display by decreasing high-shift voltage value of the pixel electrodes caused by the voltage coupling while charging pixel electrodes.

Abstract: The invention provides a touch driver circuit, by only using a select signal (Select) to control the operation of transport gates (TG1, TG2) to realize output of a valid pulse touch driver signal (TXH) and a constant low voltage signal (TXL). The circuit structure is simplified, and removes a plurality of elements and two control signals so as to reduce the layout space occupied by the touch driver circuit as well as reduced the border width of the touch display to realize narrow border design for touch display panel.

Abstract: The present invention provides a LTPS TFT substrate and a manufacturing method thereof. The LTPS TFT substrate of the present invention includes a metal layer formed on a channel zone so that the metal layer, a source electrode, and a drain electrode can be used as a mask to form LDD zones in a poly-silicon layer in order to save the mask needed for separately forming the LDD zones; further, due to the addition of the metal layer that is connected to the channel zone of the poly-silicon layer, the electrical resistance of the channel zone can be effectively reduced to increase a TFT on-state current. The LTPS TFT substrate manufacturing method of the present invention forms a metal layer on a channel zone at the same time of forming a source electrode and a drain electrode and uses the metal layer, the source electrode, and the drain electrode as a mask to form LDD zones in a poly-silicon layer so as to save the mask needed for separately forming the LDD zones thereby reducing the manufacturing cost and increasing throughput.

Abstract: A hybrid in-cell touch display panel is disclosed. A layout space occupied by transmitter driving units is reduced by halving the number of the transmitter driving units and doubling the number of strip-shaped sensing electrodes, thereby achieving an objective for reducing the size of the left and right borders.
