  • Publication number: 20180107045
    Abstract: A display panel and a display device are provided. The display panel includes an array substrate and a color film substrate forming a cell aligning structure, and a liquid crystal layer arranged between the array substrate and the color film substrate. The thickness of the liquid crystal layer is 1.5 um to 3 um. The disclosure reduces the thickness of the liquid crystal layer and greatly reduces the falling edge time of the display panel without greatly affecting the transmittance, thereby reducing the overall response time of the display panel. This can be particularly useful in situations where a moderate light transmittance is required.

  • Publication number: 20170357363
    Abstract: A control device for an electroluminescent touch-control display panel is described having a display driving circuit board, a touch-control driving circuit board, a lighting circuit board and a switching circuit board. The lighting circuit board provides a first reference signal to the touch-control driving circuit board. During the display period, the touch-control driving circuit board gates the first reference signal and transmits it to the display driving circuit board which then transmits the first reference signal to a cathode in the touch-control display panel to realize display. During the touch-control period, the touch-control driving circuit board gates an excitation signal and transmits it to the display driving circuit board which then transmits the excitation signal to the cathode and transmits a feedback signal to the touch-control driving circuit board, and the touch-control driving circuit board determines a position of touch control in accordance with the feedback signal.

  • Patent number: 9703421
    Abstract: The present disclosure provides a touch positioning method for a touch display device, and the touch display device. When it is detected that a touch operation has been made on a touch panel, whether or not the touch operation is effective is determined. When the touch operation is effective, coordinate information about a touch point are sampled multiple times, so as to acquire a plurality of initial coordinates of the touch point. A grouping calculation is performed on the plurality of initial coordinates of the touch point, so as to determine final coordinates of the touch point.

  • Publication number: 20160351100
    Abstract: Disclosed is a display driving method, an upper machine, a lower machine and a display driving system. The method includes: acquiring, by a lower machine, an address for any of subpixels transmitted from an upper machine; looking up, by the lower machine, a gray scale data corresponding to the pointer address in a display Look-UP Table (LUT), wherein the LUT stores mapping relationships between respective pointer addresses and their corresponding gray scale data; performing, by the lower machine, a digital-analog conversion on the gray scale data to acquire a converted analog voltage; and outputting the analog voltage to the subpixel so as to drive the subpixel for displaying. The method can increase the transmission rate between the GPU and the display to a certain degree and reduce the power consumption thereof.
