  • Patent number: 11636794
    Abstract: A pixel driving device includes at least one data line and at least one driver integrated circuit. The at least one data line includes a first area and a second area on both sides. The first area and the second area are separated by the at least one data line. The at least one driver integrated circuit includes a first circuit and a second circuit. The first circuit is disposed in the first area, is configured to receive at least one first high-frequency signal so as to at least one first driving signal. The second circuit is disposed in the second area, is coupled to the first circuit and is configured to receive at least one low-frequency signal.

  • Patent number: 11443675
    Abstract: A shift register circuit includes a driving signal generating circuit, a coupling circuit, and a sweep signal generating circuit. The driving signal generating circuit is configured to receive a plurality of first clock signals, a low voltage source, an initial signal, and a first high voltage source so as to output a driving signal. The coupling circuit is coupled to the driving signal generating circuit. The coupling circuit is configured to transmit the low voltage source. The sweep signal generating circuit is coupled to the coupling circuit. The sweep signal generating circuit is configured to receive a second clock signal, the low voltage source, and a second high voltage source so as to output a sweep signal. A waveform of the sweep signal includes an oblique waveform. The first high voltage source and the second high voltage source are electrically independent of each other.
