Description

The present application claims priority to Chinese patent application No. 201720110242.5, filed with the State Intellectual Property Office on Feb. 6, 2017 and titled “Container for Containing Liquid Crystal”, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the field of manufacture of display devices, and in particular to a container and a system for containing liquid crystal.

BACKGROUND

Thin Film Transistor-Liquid Crystal Displays (TFT-LCD) have advantages of stable pictures, life-like images, saving space and energy consumption, etc., and are thus widely applied to electronic products such as televisions, mobile phones and displays. To enable the TFT-LCD display function, when a TFT-LCD is manufactured, liquid crystal needs to be instilled on an array substrate before the array substrate and a color filter substrate are box aligned. Then, the box aligned array substrate and color filter substrate are encapsulated with encapsulation adhesive.
In the related art, the liquid crystal is generally stored in a liquid crystal bottle. Generally, before the array substrate and the color filter substrate are box aligned, the liquid crystal in the liquid crystal bottle is instilled on the array substrate through a conduit. The center of the bottom of the liquid crystal bottle protrudes toward the direction of the opening. Therefore, the distance from the edge of the bottom to the opening is greater than the distance from the center of the bottom to the opening.
The distance from the edge of the bottom to the opening of the above liquid crystal bottle is greater than that from the center of the bottom to the opening. Therefore, when the operation of instilling the liquid crystal is carried out every time, there is always a lot of liquid crystal remaining in the bottle. At present, the remaining liquid crystal is discarded or collected for recycling, therefore, the one-round utilization ratio of the liquid crystal in the liquid crystal bottle is relatively low.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The present disclosure will be described in further detail with reference to the enclosed drawings, to clearly present the objects, technical solutions, and advantages of the present disclosure. Apparently, the described embodiments are merely some of the embodiments of the present disclosure. Based on the embodiments of the present disclosure, other embodiments derived by a person of ordinary skill in the art without creative efforts shall be within the protection scope of the present disclosure.
The embodiments of the present disclosure provide a container for containing liquid crystal. As shown in FIG. 1, the container for containing liquid crystal includes a bottle body. The lower part of the bottle body is a concave structure 01. The bottom surface of the concave structure is a flat surface or a concave surface (the bottom surface of the concave structure as shown in FIG. 1 is a flat surface, and FIG. 1 takes the bottom surface of the concave structure being a flat surface as an example for explanation). The opening of the concave structure 01 faces to the opening 02 of the bottle body. The concave structure 01 is concave relative to the plane where the opening 02 is. 03 in FIG. 1 is a conduit for instilling the liquid crystal. The liquid crystal in the container for containing liquid crystal flows out through the conduit 03.
In summary, the container for containing liquid crystal provided by the embodiments of the present disclosure includes the bottle body. The lower part of the bottle body is a concave structure. The bottom surface of the concave structure is a flat surface or a concave surface. The opening of the concave structure faces to the opening of the bottle body. The concave structure is concave relative to the plane where the opening is. Compared with the liquid crystal bottle in the related art, when the operation of instilling the liquid crystal is carried out every time, the liquid crystal eventually remaining in the bottle will not accumulate on the edge of the bottom. Therefore, the remaining liquid crystal is less, and the one-round utilization ratio of the liquid crystal is increased.
The concave structure in the embodiments of the present disclosure may be of multiple shapes. Exemplarily, FIG. 2 shows a structural schematic diagram of another container for containing liquid crystal provided by the embodiments of the present disclosure. As shown in FIG. 2, the concave structure 01 may be funnel-shaped. The funnel-shaped concave structure enables the liquid crystal to automatically flow to the direction (the direction indicated by u in FIG. 2) away from the opening 02 under the influence of gravity. Since the conduit 03 is located in the central position of the bottom, all liquid crystal accumulates at the inlet of the conduit 03. In this way, the crystal liquid remaining in the bottle every time is less, thereby achieving the effects of saving resource and increasing the one-round utilization ratio of the liquid crystal. In order that the liquid crystal remaining in the bottle is even less, the area of the bottom surface of the concave structure may be slightly greater than the cross sectional area of the conduit.
Exemplarily, FIG. 3 shows a structural schematic diagram of another container for containing liquid crystal provided by the embodiments of the present disclosure. As shown in FIG. 3, the bottom surface of the concave structure may be a concave surface. The concave structure may be formed by a bottle wall 011 and an inward concave bottle bottom 012. The inward concave bottle bottom 012 may be a curve surface structure. The wall surface of the bottle wall 011 is a curve surface. The concave structure as shown in FIG. 3 enables the liquid crystal to automatically flow to the direction (the direction indicated by u in FIG. 3) away from the opening 02 under the influence of gravity. When flowing to the direction away from the opening, the liquid crystal accumulates at the inlet of the conduit 03. In this way, the crystal liquid remaining in the bottle every time will also be much less.
Exemplarily, the inward concave bottle bottom of the concave structure may also be as shown in FIG. 4. The inward concave bottle bottom of the concave structure may also be a flat surface structure. The inward concave bottle bottom of the flat surface structure enables the liquid crystal to automatically flow to the direction away from the opening 02 under the influence of gravity, so that all the crystal liquid can accumulate at the inlet of the conduit 03. In this way, the crystal liquid remaining in the bottle is reduced. The inward concave bottle bottom in the present disclosure may be of multiple shapes, which will not be limited by the present disclosure. In order that the liquid crystal remaining in the bottle is even less every time, the area of the bottom surface of the concave structure in FIG. 4 may be slightly greater than the cross sectional area of the conduit. In FIG. 4, 02 is the opening and 03 is the conduit.
Exemplarily, FIG. 5 shows a structural schematic diagram of yet another container for containing liquid crystal provided by the embodiments of the present disclosure. As shown in FIG. 5, the bottom surface of the concave structure may be a flat surface. The concave structure is circular truncated cone-shaped. The concave structure as shown in FIG. 5 enables the liquid crystal to automatically flow to the direction away from the opening 02 under the influence of gravity, so that all the crystal liquid can accumulate at the inlet of the conduit 03. In this way, the crystal liquid remaining in the bottle every time is less. In order that the liquid crystal remaining in the bottle is even less, the area of the bottom surface of the concave structure may be slightly greater than the cross sectional area of the conduit.
Exemplarily, FIG. 6 shows a structural schematic diagram of yet another container for containing liquid crystal provided by the embodiments of the present disclosure. FIG. 6 shows the structural schematic diagram of another concave structure. The bottom surface of the concave structure is also a flat surface. The inner wall of the concave structure is a curve surface. The concave structure as shown in FIG. 6 enables the liquid crystal to automatically flow to the direction away from the opening 02 under the influence of gravity, so that the crystal liquid can accumulate at the inlet of the conduit 03 similarly. In order that the liquid crystal remaining in the bottle is even less, the area of the bottom surface of the concave structure may be slightly greater than the cross sectional area of the conduit.
In some embodiments, as shown in FIGS. 3 to 6, a cavity 013 may be disposed between the inner wall of the concave structure and the outer wall of the bottle body to reduce the weight of the bottle body. In the embodiment of the present disclosure, disposing the cavity 013 can reduce the weight of the bottle body.
In addition, another structure of the bottle body as shown in FIG. 4 may be shown in FIG. 7-1, and the bottom of the bottle body is of an irregular shape. Another structure of the bottle body as shown in FIGS. 3, 5 and 6 may also be obtained by referring to the structure of the bottle body as shown in FIG. 7-1. Exemplarily, FIG. 7-2 is another structural schematic diagram of the bottle body as shown in FIG. 3, FIG. 7-3 is another structural schematic diagram of the bottle body as shown in FIG. 5, and FIG. 7-4 is another structural schematic diagram of the bottle body as shown in FIG. 6.
In some embodiments, as shown in FIG. 7-1, the wall thickness is equal throughout the bottle body. In order to enable the bottle to be more stable, further, a support frame 04 may be sleeve-connected to the concave structure of the bottle body. Exemplarily, the support frame may be a columnar structure. The columnar structure is provided with a cavity, and one end of the columnar structure is provided with an opening. The support frame may be made of wood.
Further, in order to improve the stability of the container for containing liquid crystal, as shown in FIG. 7-5, a plurality of locating elements 041 supporting the container for containing liquid crystal may be disposed at the opening of the support frame 04. Exemplarily, 2 locating elements may be disposed at the opening of the support frame. Each locating element may be made of rubber.
In some embodiments, the area of the bottom surface of the concave structure may be equal to the cross sectional area of the opening.
Exemplarily, the bottle body may be made of plastics, metal or glass.
FIG. 8 shows a structural schematic diagram of a liquid crystal bottle in the related art. As shown in FIG. 8, the distance d1 between the edge of the bottom and the opening 02 of the liquid crystal bottle is greater than the distance d2 between the center of the bottom and the opening 02. While the conduit 03 for instilling the liquid crystal is generally located in the central position of the bottom. Therefore, when the operation of instilling the liquid crystal is carried out every time, there is a lot of the liquid crystal eventually remaining in the bottle. Generally, about 20 g of liquid crystal will remain from 500 g of liquid crystal. The remaining liquid crystal every time will be discarded, which causes resource waste, or will be collected for recycling, of which the cost is higher.
Before carrying out the operation of instilling the liquid crystal with the container for containing liquid crystal provided by the embodiments of the present disclosure, the liquid crystal is poured into the container for containing liquid crystal first. Then the conduit is inserted into the container for containing liquid crystal. After that, the liquid crystal in the liquid crystal bottle is instilled onto the array substrate through the conduit. When the liquid crystal in the container for containing liquid crystal is too little, the conduit is likely to instill the liquid crystal containing air onto the array substrate. As a result, bubbles can appear on the array substrate, which affects the display effect of the display device. Therefore, in order to guarantee the display effect of the display device, it is required that a certain amount of the liquid crystal of remains in the container for containing liquid crystal eventually.
In summary, the container for containing liquid crystal provided by the embodiments of the present disclosure includes the bottle body. The lower part of the bottle body is a concave structure. The bottom surface of the concave structure is a flat surface or a concave surface. The opening of the concave structure faces to the opening of the bottle body. The concave structure is concave relative to the plane where the opening is. Compared with the liquid crystal bottle in the related art, when the operation of instilling the liquid crystal is carried out every time, the liquid crystal eventually remaining in the bottle will not accumulate on the edge of the bottom. Therefore, the remaining liquid crystal is less, and thus the one-round utilization ratio of the liquid crystal is increased. Besides, the structure of the container for containing liquid crystal is simple, which can be easily realized.
The embodiments of the present disclosure also provide a system for containing liquid crystal, comprising the container for containing liquid crystal and the conduit disposed in the container for containing liquid crystal. Wherein, the container for containing liquid crystal includes the bottle body. The lower part of the bottle body is a concave structure. The bottom surface of the concave structure is a flat surface or a concave surface. The opening of the concave structure faces to the opening of the bottle body. The liquid crystal in the container for containing liquid crystal flows out of the container for containing liquid crystal through the conduit. Since the concave structure of the bottle body of the container for containing liquid crystal is concave relative to the plane where the opening is, when the operation of instilling the liquid crystal is carried out every time, the liquid crystal eventually remaining in the bottle will not accumulate on the edge of the bottom. Therefore, the remaining liquid crystal is less, and thus the one-round utilization ratio of the liquid crystal is increased. Besides, the structure of the container for containing liquid crystal is simple, which can be easily realized.
The foregoing are only preferred embodiments of the present disclosure, and are not intended to limit the present disclosure. Within the spirit and principles of the present disclosure, any modifications, equivalent substitutions, improvements, etc., are within the scope of protection of the present disclosure.
