  • Patent number: 10699631
    Abstract: A LED sensing system and a display panel sensing system are disclosed. The LED sensing system comprises LEDs and a driver. The LEDs are arranged in a LED array, and the driver is disposed on a central portion of the LED array and electrically connected to the LEDs respectively. The driver can receive an activation maintenance signal, and receive an input address, and turn on one of the LEDs corresponding to the input address, so as to obtain a magnitude of a voltage of the LED corresponding to the input address for determining performance of the LED and a yield rate of the LED array.

  • Patent number: 8669974
    Abstract: A timing controller adapted to a flat display includes a voltage detecting circuit, a clock generator, a first multiplexer and a second multiplexer. The voltage detecting circuit detects a variation of an operating voltage and thus outputs a reset signal. The clock generator outputs a start signal and a first clock signal. The first multiplexer is controlled by the reset signal and coupled to the start signal and a constant voltage. The second multiplexer is controlled by the reset signal and coupled to the first clock signal and a second clock signal. A frequency of the second clock signal is obviously higher than a frequency of the first clock signal.
