Problems solved by technology

The UV masks of all products of different sizes are independent. Every time a product is developed, a corresponding UV mask needs to be developed. This method will increase the production cost of the display device, which is not conducive to the reduction of the liquid crystal manufacturing cost. Control

Embodiment Construction

[0035] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] like figure 1 , figure 2 As shown, the present invention provides a kind of UV mask plate, and this UV mask plate comprises: mask plate body 1 and shading plate 2 (not shown in the figure); Described mask plate body 1 comprises shading area 11 and light leakage Area 12; a light leakage area 12 is formed between the adjacent light shielding areas 11; the light leakage area 12 is a slit 121 in the first direction or a slit 122 in the second direction; the light shielding sheet 2 is used to block the non-exposed area. The UV mask provided by the present invention will be described in detail below.

[0037] like figure 1 , figure 2 As shown, the directions of the...

Abstract

The invention discloses an ultraviolet (UV) mask and an exposure method thereof. The UV mask comprises a mask body and a shading plate, wherein the mask body comprises shading areas and a light-leaking area; the light-leaking area is formed between the adjacent shading areas, and is a gap in a first direction or the gap in a second direction; and the shading plate is used for shading a non-exposure area. Substrates are exposed in a shading manner of splicing the mask and the shading plate, so that the shared effect of the UV mask is reached. The substrates with different sizes can be exposed, developed and fabricated by the UV mask disclosed by the invention; and the UV mask does not need to be individually opened, so that the fabrication cost of a display device is reduced.

Description

technical field [0001] The invention relates to a UV mask plate and an exposure method thereof, belonging to the technical field of liquid crystal manufacturing. Background technique [0002] Liquid Crystal Display (LCD, Liquid Crystal Display) and other display devices are widely used flat display devices. The manufacturing method generally includes: providing two parallel substrates, and applying a sealant between the two substrates. ) and the liquid crystal poured into the space formed by the sealant and two base substrates; the thin film field effect transistor (TFT, Thin Film Transistor) is arranged on the lower substrate, and the color filter (CF, Color Filter) is arranged on the upper substrate , by changing the signal and voltage on the TFT to control the rotation direction of the liquid crystal molecules in the liquid crystal cell, so as to control whether the polarized light of each pixel is emitted or not to achieve the display purpose. [0003] In the existing l...
