  • Patent number: 11455057
    Abstract: An object of the present invention is to efficiently reduce the number of signal lines of a control port and an input port of a sensor switch required for controlling a touch by supplying a programmable voltage from a touch drive IC TDI, not a separate external voltage source, as a voltage applied to a touch sensor. The present invention provides a touch screen which is capable of implementing low power consumption, low-resistance signal wiring, touch IC price reduction, and the like by forming a switching transistor of the sensor switch only with a P-type transistor manufactured in a Low Temperature Poly Silicon (LTPS) process, and driving the switching transistor without using a negative voltage (?V).

  • Patent number: 11361728
    Abstract: A liquid crystal display apparatus including a gate driving circuit disposed on a liquid crystal display is provided. The apparatus further includes a data driving chip, disposed on the liquid crystal display panel, to apply data driving signals to data lines. The gate driving circuit includes a plurality of stages connected to one another in parallel. The odd-numbered stages of the stages each apply gate driving signals to odd-numbered gate lines of the gate lines, in response to a first clock signal and the even-numbered stages of the stages each apply the gate driving signals to even-numbered gate lines of the gate lines, in response to a second clock signal having an opposite phase from a phase of the first clock signal.

  • Patent number: 11093076
    Abstract: The present invention relates to a design for optimally mounting a Touch Drive (IC) (TDI) signal line and a Display Drive IC (DDI) signal line of a display apparatus having a touch function. According to the display apparatus having a touch function and the method of mounting the signal line of the display apparatus according to the present invention, the TDI signal line and the DDI signal line are mounted so as not to overlap in the bending region on the same flexible substrate, thereby preventing the problem, such as cracks, in the related art. Further, according to the display apparatus having a touch function and the method of mounting the signal line of the display apparatus according to the present invention, it is possible to easily manufacture a full-screen display apparatus by reducing a length of a fan-out area of the TDI signal line.
