  • Patent number: 11238817
    Abstract: A method and an apparatus for pixel signal conversion are provided. The method includes: based on an initial first subpixel signal, an initial second subpixel signal, and an initial third subpixel signal of a pixel signal, obtaining a corresponding first stimulus value signal, second stimulus value signal, and third stimulus value signal. When converted pixel signals are applied to a hybrid-color display consisting of subpixels of four colors of W, R, G, and B, a display effect is closer to actual representation of original hybrid colors of R, G, and B, to alleviate a color shift defect of a large view angle.

  • Patent number: 11217146
    Abstract: A gray-level compensation method and apparatus, a display device and a computer storage medium are provided, which belong to the field of display technology. The method includes: acquiring an initial gray-level value of a target pixel; determining an actual luminance offset of the target pixel based on the initial gray-level value, where different initial gray-level values within a specified threshold range correspond to different actual luminance offsets; and performing a gray-level compensation on the target pixel based on the actual luminance offset. The actual luminance offset is determined based on the initial gray-level value of the target pixel, and since the different initial gray-level values within the specified threshold range correspond to the different actual luminance offsets, flexibility of gray-level compensation performed on the pixel is improved.

  • Patent number: 11211026
    Abstract: A display device capable of improving image quality is provided. The display device includes a first circuit, a pixel, and a wiring. The first circuit has a function of supplying data to the wiring and a function of making the wiring floating to hold the data. The pixel has a function of taking in the data twice from the wiring and performing addition. The pixel can perform the first writing of the data in a period during which the data is supplied to the wiring, and can perform the second writing of the data in a period during which the data is held in the wiring. Therefore, by one time of data charging to a source line, a data potential larger than or equal to an output voltage of a source driver can be supplied to a display element.

    Abstract: An array substrate and a display device are provided. An antistatic conductive wire is disposed in the non-display region, and the antistatic conductive wire comprises at least two antistatic conductive layers. An antistatic conductive layer is firstly formed in the fabrication processes, and the antistatic conductive layer has a function of antistatic to prevent static electricity from generating in the processes. After other antistatic conductive layers are formed, a capacitor structure is formed between antistatic conductive layers. Meanwhile, the static discharge is more easily performed in the opposite direction of the antistatic conductive multi-layer.

  • Patent number: 11107376
    Abstract: A low drag outdoor media façade display for mounting on a structure susceptible to instability when exposed to strong winds, having an array of radiating elements thinly dispersed about the façade area, held by an array of thin suspension elements, the elements are spaced apart leaving gaps, such that the total surface area of the elements is smaller than the total area of the façade display. A tilting mechanism, active or passive, is operational for tilting the façade display or at least one element thereof. The passive mechanism allows free tilt in response to wind blow, and the elements may include tails. The active mechanism is operational for altering wind load drag profile of the façade display to accommodate wind conditions. The display may be inflatable or collapsible sail-like. A display featuring a liquid spray curtain for refracting or reflecting light projections is a further measure for reducing wind load.
