Problems solved by technology

[0006] The invention provides a frame sealing glue curing device and its mask plate, which are used to solve the problem of the airflow formed by the movement of the liquid crystal panel away from the mask plate after the exposure and curing of the frame sealant by the mask plate, resulting in the adsorption of the mask plate The load increases, causing the mask to fall off and damage the LCD panel

Embodiment 1

[0030] Such as figure 1 As shown, a mask 10 for curing the frame sealant is provided in this embodiment, which includes a light-transmitting region 100 and a light-shielding region 101, and the light-transmitting region 100 of the mask for curing the frame sealant on the liquid crystal panel It is a plurality of strip-shaped light-transmitting areas that intersect horizontally and vertically (such as figure 1 102, 103 in ), the area defined by the intersection of the strip-shaped light-transmitting areas is the light-shielding area 101, which corresponds to the display area of ​​the liquid crystal panel. For the convenience of description, the extending direction of the length of the liquid crystal panel is defined as the horizontal direction, and the extending direction of the width is defined as the vertical direction.

[0031] At least one through hole 3 is provided in the light-transmitting area 100, mainly serving as an air intake hole. combine figure 2 As shown, afte...

Embodiment 2

[0039] Such as figure 2 As shown, this embodiment provides a sealing sealant curing device, which includes a mask plate 10 and a vacuum suction device for fixing the mask plate 10, wherein the mask plate 10 adopts the mask plate in the first embodiment , used to reduce the risk of the mask plate 10 coming off due to the pressure difference, and ensure the mass production efficiency of the sealing glue curing device.

[0040] Specifically, the vacuum adsorption device is adsorbed on the upper surface of the mask plate 10 . An object stage 30 is provided below the mask plate 10 for fixing the liquid crystal panel 20 cured by the pre-seal sealant. And a driving device (not shown in the figure) is provided to drive the stage 30 to move, so that the liquid crystal panel 20 fixed thereon is away from the exposure position (the exposure position is about 3mm) or reach the exposure position.

[0041] Wherein, the vacuum adsorption device may be a plurality of transparent rods 1, s...

Abstract

The invention relates to the technical field of LCD (Liquid Crystal Display), and discloses a frame sealing glue solidifying device and a mask plate thereof. The mask plate comprises a light transmitting zone and a light shielding zone, wherein the light transmitting zone is provided with at least one through hole. In a descending preliminary stage that a liquid crystal panel is far away from the mask plate after exposure solidification of frame sealing glue is finished, due to the arrangement of the through hole, the air inlet area is enlarged, the air inlet amount is enlarged, the air inlet speed is reduced, the pressure difference of the space between the liquid crystal panel and the mask plate and the surrounding environment is lessened, the pressure acting on the mask plate by the pressure difference is lessened under the same action area, and thus the load of absorbing the mask plate by vacuum is reduced; meanwhile, due to the existence of the through hole, the action area of the pressure difference on the mask plate is reduced, and the load of absorbing the mask plate by vacuum is further reduced; therefore, according to the technical scheme of the invention, the risk that the mask plate falls off due to the pressure difference is greatly reduced while the descending speed of the liquid crystal panel is not reduced, and the volume production efficiency is ensured.

Description

technical field [0001] The invention relates to the field of liquid crystal display technology, in particular to a frame sealing glue curing device and a mask plate thereof. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has the characteristics of small size, low power consumption, and no radiation. It has developed rapidly in recent years and occupies a dominant position in the current flat panel display market. The liquid crystal panel is the core component of TFT-LCD, including the array substrate and the color filter substrate arranged in opposite cells, and the liquid crystal filled between the array substrate and the color filter substrate. At present, the box-forming process of LCD panels often adopts the One Drop Fill (ODF) method, which specifically includes: firstly coating the liquid crystal and frame sealant on the surface of the array substrate or color film substrate, and then performing the box-fitting process . In this w...
