Embodiment Construction

[0042]In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and which show by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terms such as "top", "bottom", "left", "right", "upper", "lower", etc. are used with reference to the orientation of the figures being described. Because components of an embodiment may be positioned in several different orientations, directional terminology is used for purposes of illustration and is by no means limiting. It is to be understood that other embodiments may be utilized or logic changes may be made without departing from the scope of the present invention. The following detailed description should therefore not be taken in a limiting sense, and the scope of the invention is defined by the appended claims.

[0043] It should be understood that the features of the various exemplary embodiments described herein can be comb...

Abstract

According to one aspect of the present invention, a mask plate is proposed, which includes a first transparent substrate on which sequentially formed: a first transparent electrode, an electrochromic layer and a second transparent electrode, the The first transparent electrode is configured to receive selective power supply to form electrified regions of different shapes. According to other aspects of the present invention, a method for manufacturing the reticle, an apparatus including the reticle, and a method of using the reticle are proposed.

Description

technical field [0001] The present invention relates to the manufacturing field of display devices, in particular to a mask plate, a manufacturing method, a use method thereof, and a device including the mask plate. Background technique [0002] In the TFT-LCD manufacturing process, the UV mask (UV Mask, also known as a mask) is mainly used for the photocuring of the sealant and the removal of the edge alignment film of the active area (Active Area). Protective shielding of the area (liquid crystal is an organic compound that will decompose under strong ultraviolet radiation, short-term exposure will reduce its resistivity, and long-term exposure will make its color yellow, which will affect the display effect). [0003] In the prior art, usually according to the different sizes of the display panels, UV shields of corresponding sizes are manufactured. figure 1 A schematic structural view of a conventional ultraviolet light shield is shown in , wherein the ultraviolet light...
