  • Patent number: 11069293
    Abstract: A luminance controlling unit includes a luminance controller that controls luminance of a pixel array including pixels each including a current-driven self-luminescent element. The luminance controller performs, on the basis of an image signal, a dynamic control of a duty ratio of a voltage pulse and a potential difference between a first voltage and a second voltage. The first voltage is outputted from a first voltage source adjacent to an anode of the corresponding self-luminescent element, and the second voltage is outputted from a second voltage source adjacent to a cathode of the corresponding self-luminescent element. The duty ratio is directed to controlling of light emission and light extinction of the self-luminescent element.

  • Patent number: 11054710
    Abstract: A display device capable of performing image processing is provided. Each pixel is provided with a memory circuit, and desired correction data is held in the memory circuit. The correction data is calculated in an external device and written into each pixel. The correction data is added to image data owing to capacitive coupling, and the resulting data is supplied to a display element. Thus, a corrected image can be displayed with the display element. The correction enables image upconversion or can compensate for an image quality reduction due to characteristics variations of transistors included in pixels.

  • Patent number: 11056549
    Abstract: The present disclosure provides an active matrix organic light emitting diode panel where a color shift does not occur at an edge of a display area. A color shift does not occur at the edge of the display area in an AMOLED panel proposed by an embodiment of the present disclosure to avoid color shift phenomenon at the edge of a display area. So red, green, and blue (R, G, and B) pixel units that are not arranged in a regular pattern at a non-standard pixel structure and a corresponding anode material layer are in a floating state. So the color shift phenomenon will not occur. When the pixel unit of the non-standard pixel structure receives an image display control signal, the color shift phenomenon may occur due to the inability to correspondingly display a corresponding image corresponding to the image display control signal to display the screen normally.

A structure includes a first functional layer having first functional components of the IC with first test scan chains and a second functional layer having second functional components of the IC with second test scan chains. A dedicated test layer is located between the first functional layer and the second functional layer. The test layer includes an interface register controlling signals from a testing module to one of the first test scan chains and the second test scan chains, and an instruction register connected to the interface register. The instruction register processes testing instructions from the testing module. Inter-layer vias connect the first functional components, the second functional components, and the testing module through the test layer.
