  • Patent number: 11635651
    Abstract: The invention provides a display panel, which includes a first substrate, a second substrate, a liquid crystal layer, a light shielding pattern layer and a plurality of pixel structures. The liquid crystal layer is disposed between the first substrate and the second substrate, and includes a plurality of negative liquid crystal molecules. Each of the pixel structures includes a first electrode and a second electrode. The first electrode has an electrode opening and a first finger portion extending into the electrode opening. The second electrode has two second finger portions overlapping the electrode opening. The first finger portion and the two second finger portions are alternately arranged along a first direction inside the electrode opening and extend in a second direction.

  • Patent number: 11112641
    Abstract: The present invention provides a display panel having a display region and a peripheral region, and the display panel includes a plurality of pixel units including at least one inner pixel unit and at least one first peripheral pixel unit, and a shielding layer. A shape of the display region is non-rectangular. The inner pixel unit is disposed in the display region and includes at least one inner sub-pixel unit. The first peripheral pixel unit is disposed in both the display region and the peripheral region and includes at least one first peripheral sub-pixel unit. At least a part of the shielding layer is disposed in the peripheral region, and the at least a part partially overlaps the first peripheral pixel unit. A structure of the first peripheral pixel unit is different from a structure of the inner pixel unit.

  • Patent number: 9128324
    Abstract: A display device includes a transparent display panel and an adjustable light valve. The transparent display panel and the adjustable light valve are disposed opposite to each other. The transparent display panel includes a plurality of pixels including active-matrix organic light-emitting diodes for generating an image. When the display device operates under a transparent display mode, the adjustable light valve is in a transparent status. When the display device operates under a high color saturation display mode, the adjustable light valve is in a non-transparent status. Thereby, the display device will not be limited to having only a display mode.

  • Patent number: 9081241
    Abstract: A pixel structure and a method for manufacturing the same are disclosed. The pixel structure of the present invention is a pixel structure implemented by combining an in-plane switching (IPS) technique and a fringe field switching (FFS) technique. In each pixel structure, two transparent conductive layers are utilized to form a storage capacitor (Cst) such that the capacitance of the storage capacitor can be increased without decreasing an aperture ratio of a display panel, and thereby a feedthrough voltage can be reduced so as to prevent a screen from blinking.
