  • Patent number: 11963300
    Abstract: A panel device including a substrate, a conductor pad, a turning wire, and a circuit board is provided. The substrate has a first surface and a second surface connected to the first surface while a normal direction of the second surface is different from a normal direction of the first surface. The conductor pad is disposed on the first surface of the substrate. The turning wire is disposed on the substrate and extends from the first surface to the second surface. The turning wire includes a wiring layer in contact with the conductor pad and a wire covering layer covering the wiring layer. The circuit board is bonded to and electrically connected to the wire covering layer. A manufacturing method of a panel device is also provided herein.

  • Patent number: 8803833
    Abstract: A touch panel includes a display module, a touch sensor and a signal processing unit. The display module includes a timing control circuit and a data driving circuit, wherein the timing control circuit outputs latch signals to the data driving circuit, and the display module generates surface noises. The touch sensor is disposed above the display module and outputs abnormal signals, wherein the abnormal signals include a sensing signal and the surface noises. The signal processing unit is electrically connected to the touch sensor and receives the abnormal signals, wherein the signal processing unit calculates a predetermined time by utilizing a rising edge or a falling edge of the latch signal, suspensively processes the sensing signal during the predetermined time, and then continuously processes the sensing signals beyond the predetermined times so as to keep away from each period of the surface noises.

  • Patent number: 8593212
    Abstract: A signal-noise ratio control system which reduces noise interference includes a touch sensor, a touch controller, and a level shifter. The touch sensor is driven by a driving signal and outputs an analog signal based on a touch situation. The touch controller generates the driving signal and provides a divided voltage based on the analog signal. The level shifter adjusts a voltage level of the driving signal based on a voltage level of the divided voltage.

  • Publication number: 20130038586
    Abstract: A liquid crystal display device including a liquid crystal panel, a gate driver unit, a source driver unit and a clock generator and a method thereof are disclosed to improve display quality. The liquid crystal panel comprises a pixel array for displaying images. The gate driver unit for generating plural driving signals drives the pixel array. The source driver unit for generating plural driving signals drives the data of the image signals. The clock generator electrically coupled to the gate driver unit generates clock signals to control an operation of the gate driver unit. A bright line is likely to occur in an image area since the last two gate driver output lines of the last two stages are not coupled to the liquid crystal panel. A solution with the duty cycle of a clock signal generated by the clock generator is adjusted to solve the aforementioned problem.
