  • Patent number: 11646574
    Abstract: A driving circuit includes at least one first module, an electrostatic charge/discharge module connected to the first module and a grounding module; each first module includes a driving module, a signal transmission module and a gating module; the signal transmission module is connected to and transmits a driving signal to the driving module; the grounding module is grounded; the gating module is connected with the signal transmission module; the gating module is turned on with its turn-on voltage less than or equal to a voltage of the signal transmission module, or turned off with the turn-on voltage greater than the voltage of the signal transmission module; the turn-on voltage of the gating module is greater than that of the driving module; the charge/discharge module is connected to the gating module and the grounding module, and configured to store charges flowing therethrough and release the charges to the grounding module.

  • Patent number: 11567358
    Abstract: Provided are a color film substrate and manufacturing method thereof, and a display panel and manufacturing method thereof. The color film substrate is divided into a display region, and a non-display region around a periphery of the display region and including an edge region at an edge of the color film substrate. The color film substrate includes base, color resist layer on the base and black matrix layer on the base at least in the display region. In the edge region, the color resist layer includes first sub color resist layer on the base and second sub color resist layer on the first sub color resist layer, the first sub color resist layer allows light in first wavelength range to transmit therethrough, the second sub color resist layer allows light in a second wavelength range to transmit therethrough, and the first wavelength range does not overlap the second wavelength range.
