A liquid crystal display device includes a plurality of data lines; a plurality of gate lines and a pixel array including a plurality of subpixels formed of first-color to fourth-color subpixels. The plurality of subpixels has a first arrangement or a second arrangement. The first arrangement is an arrangement in which in each row of the pixel array two of the first-color to fourth-color subpixels is interleaved. The second arrangement is a different arrangement than the first arrangement in which in each row of the pixel array two of the first-color to fourth-color subpixels are interleaved. A data driver is configured to drive the pixel array according to a first driving method when the pixel array has the first arrangement and drive the pixel array according to at least one second driving method that is different from the first driving method when the pixel array has the second arrangement.

Provided is a display device. A poly-Si layer is disposed on a substrate. A first metal layer is disposed on the poly-Si layer, and a metal oxide layer is disposed on the first metal layer. A second metal layer is disposed on the metal oxide layer. The first metal layer is overlapped with the second metal layer. The first metal layer and the second metal layer may be gate lines connected to different TFTs. Thus, in the display device, a plurality of gate lines may be disposed so as to be overlapped with each Oxide other. Therefore, an area occupied by a circuit part in the display device can be reduced. Accordingly, it is possible to manufacture a display device with higher resolution, a transparent display device with improved transmittance, and a display device with a reduced size of a non-display area.

Provided is a display device including a display unit and a mirror unit adjacent to each other, in which the display unit includes a first substrate, a thin film transistor formed on the substrate, a pixel electrode connected to the thin film transistor, a roof layer formed on the pixel electrode to be spaced apart from the pixel electrode with a microcavity therebetween, and a liquid crystal layer filling the microcavity, and the mirror unit includes a second substrate, a first electrode formed on the second substrate, a second electrode formed on the first substrate to be spaced apart from the first electrode with a microcavity therebetween, and an electrochromic layer formed in the microcavity.

An array substrate, an electrochromic display and a method for driving the array substrate are disclosed. A display region of the array substrate (30) comprises a plurality of sets of data lines (33) and a plurality of scan lines (36), the plurality of sets of data lines (33) and the plurality of scan lines (36) intersecting each other to divide the display region into a plurality of pixel regions, a pixel electrode (32) is disposed in each of the pixel regions and electrically connected to the data lines (33); the pixel electrode (32) comprises a central pixel electrode (32a) and a peripheral pixel electrode (32b) adjacent to and electrically isolated from the central pixel electrode (32a). When the pixel region is driven, the peripheral pixel electrode (32b) and the central pixel electrode (32a) are at opposite polarities, thereby making the electrochromic material flowing from the central pixel region (32a) corresponding to the central pixel electrode (32a) to the peripheral pixel electrode (32b) and having been changed in color to fade in color. Cross-talk between adjacent pixel regions in the electrochromic display panel can be effectively controlled, and the display effect of the electrochromic display can be improved.

Chromatic systems and structures are presented that operate without external electrical supply, which enable changes in color or transparency of a substrate material, such as glass. Various configurations provide a mechanism to activate an oxidation-reduction reaction in a chromatic material, so as to change from transparent to opaque or from one color to another. These structures may be used in applications from windows for buildings and homes, camera lenses, automotive displays and windows, mobile device displays, and other applications where chromatic change is desired.
