    摘要： The present disclosure provides a display panel and a display device, The display panel comprises a first area and a second area, comprises a plurality of first pixel rows, and a plurality of second pixel rows, and each of the first pixel row and the second pixel row comprise a plurality of pixels, the number of the pixels of each first pixel row is greater than the number of the pixels of each second pixel row. The pixels in the first pixel row are display pixels, and the plurality of pixels in the second pixel row are display pixels and virtual pixels. The display pixel comprises a display pixel circuit, the virtual pixel comprises a virtual pixel circuit, and the virtual pixel circuit comprises a compensation unit. The virtual pixel circuit is configured to reset and compensate the display pixel circuit located in the same second pixel row, so that, after the display pixel circuits in both the first area and the second area are reset, a voltage difference of nodes of light-emitting devices corresponding to the display pixel circuits is reduced, and the display effect is improved.

    摘要： A LED controller for an LED pixel array includes a serial interface to an external data bus, along with an address generator connected to the serial interface and the LED pixel array. An image frame buffer is connected to the interface to receive image data and further connected to the address generator to receive an image frame buffer address. A command and control module is connected to the serial interface and configured to modify image frame buffer output signals. A calibration data storage module is connected to the command and control module to store calibration data related to pixel voltage response in the LED pixel array and enable modification of voltage provided by the dynamic power supply at least in part based on the image presented by the LED pixel array.

    摘要： An electroluminescent paint indicator for a fault or failure may include at least one layer of electrically conductive paint (200) disposed on a surface (108) within a system (100) including the electroluminescent paint indicator, at least one dielectric layer (202) disposed on the at least one layer of electrically conductive paint, at least one layer including an electroluminescent phosphor compound (204) disposed on the at least one dielectric layer, and at least one layer of conductive coating (206) disposed on the at least one layer including the electroluminescent phosphor compound. The electroluminescent paint indicator may be configured to activate following a determination of a fault or failure with the at least one layer of electrically conductive paint receiving power, the at least one layer including the electroluminescent phosphor compound being excited by the at least one layer of electrically conductive paint, and the least one layer including the electroluminescent phosphor compound generating an illuminated light (214).
