    Abstract: The embodiments of the invention disclose an array substrate, a manufacturing method thereof and a display device. Due to the fact that the surfaces of a source electrode, a drain electrode and a data line which are arranged on the same layer are provided with an oxide film which is formed after annealing treatment is conducted on the source electrode, the drain electrode and the data line, in the process that the pattern of a pixel electrode is formed on the source electrode, the drain electrode and the data line by the adoption of a composition technology, the oxide film can protect the source electrode and the data line under the oxide film from being corroded by an etching agent when the pattern of the pixel electrode is formed by etching, and the display quality of a display panel will not be affected.

    IPC: G06T3/00

    CPC classification number: G06T3/0093

    Abstract: There are provided a display compensation method, a display compensation module and a display apparatus. The method comprises following steps: receiving an image signal to be displayed (S1); obtaining a user position (S2) which is a relative position of a user relative to a the display apparatus; compensating for the image signal to be displayed according to the user position to obtain a compensated image signal (S3); and outputting the compensated image signal (S4). The display compensation method, the display compensation module and the display apparatus can be used for manufacturing the display, and can avoid the image distortion occurred to the image viewed by the user due to the different distances from the user to respective points on the display such that the user's experience in the display effect of the display can be raised.

    Abstract: In the light guide plate, a surface of the reflection sheet away from the bottom surface is configured as a reflection surface. Regions of the light guide plate body except the reflection sheets are configured as light transmission regions. The light transmission regions and the reflection sheets are alternately arranged; a plurality of transmission protrusions are disposed at the light transmission region inside the light guide plate body; a reflection coating layer is formed on side surfaces of each of the transmission protrusion. Since the reflection sheets are provided inside the light guide plate body, the reflection sheet reflects light which is directed from the one surface and passes through the display panel, and prevents the light, directed from the other surface of the display apparatus, from passing through the display panel and interfering with the normal display of the one surface.

    Abstract: The present disclosure provides an array substrate, its manufacturing method and a display device. The method includes forming a source electrode and a drain electrode of a thin film transistor, an active layer and a first transparent electrode in the array substrate by a masking step. The active layer and the first transparent electrode are formed by an identical metal oxide layer, and the source electrode and the drain electrode are arranged above the active layer. The first transparent electrode corresponds to a first semi-transparent region of a mask, a channel region of the thin film transistor corresponds to a second semi-transparent region of the mask, the source electrode and drain electrode of the thin film transistor correspond to a non-transparent region of the mask, and the first semi-transparent region of the mask is of transmittance greater than that of the second semi-transparent region of the mask.
