JPH068623Y2 - Peripheral structure of dimming display - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is applied to liquid crystal, electrochromic, light valve,
The present invention relates to a light control display body in which a display material is enclosed, such as a plasma display, and particularly to a peripheral structure thereof.

[Prior art and its problems]

The applicant previously mentioned in Japanese Patent Application No. 63-165820, in a display body in which a narrow overflow gap of a pair of glass plates is filled with a display material and the inner edge of the glass plate is sealed with a sealing material. Proposed to make the sealing material sealing part as a roughened surface in advance as an enlarged gap, to firmly adhere the sealing material to the glass plate, and to expand or contract the internal pressure between the glass plates at the time of production or use, It has been mentioned that this can be endured and that the display material can be easily injected.

The present invention relates to the improvement, and provides a peripheral structure of a dimming display body in which injection of a display material is facilitated.

[Means for solving problems]

The present invention provides a dimming display body in which the peripheral portions of glass plates facing each other are sealed with a sealing material, and the gap between the glass plates is filled with a display material. A sealing material layer, a sealing material blocking member, and a display material injection space are sequentially provided in the enlarged gap in this order from the external space side.

〔Example〕

 Hereinafter, the present invention will be described with reference to the accompanying drawings.

FIG. 3 is a partial perspective view showing an example of a peripheral structure of a conventionally known dimming display, in which a sealing material layer 3 and a spacer 4 are arranged in order from the outside in the peripheral part between the glass plates 1 and 1 '. Further, a groove 6 is formed on the inner surface of at least one of the glass plates 1 inside the glass plate 1 for inserting the injection pipe 5 for the display material, and the display material is the injection pipe as shown by the arrow (→) in the figure. It is discharged from the slit portion of No. 5. However, it is not easy to form a groove on the surface of the glass plate, it is easy to cause chipping or breakage, and stress is applied to the groove portion 6 when the glass plate is bent during injection or use of the display material. It is easy to concentrate and crack damage.

FIG. 1 is a partial perspective view according to the present invention, and FIG. 2 is a corresponding partial cross-sectional plan view, in which at least one of the glass plates 1 and 1 ′ is ground to a rough surface 2 on the inner surface of the peripheral part thereof, Inner gap B that fills the glass plate gap A (shown in FIG. 2) with the display material.
In the enlarged gap A, a sealing material layer 3 such as a silicone resin, a sealing material blocking member 4 ', and a display material injection space 7 are arranged from the outside in the enlarged gap A.

By using the glass plate 1 as the ground rough surface 2, the anchoring action of the sealing material 3 is increased. In addition, the inner surface grinding of the glass plate periphery is easier than the above-mentioned groove formation on the plate surface, and it is less likely to chip or break, and even if the glass plate bends when the display material is injected or used, the groove will be damaged. Rather, the sealing material 3 sealing width is increased, and the expansion / contraction shrinkage margin length of the sealing material 3 is increased, so that the sealing material 3 can be easily escaped from damage or the like.

The dam portion 4'is provided to prevent the sealing material 3 from entering the space 7 for forming the display material injection space 7, and can of course also be used as an end spacer.

It is easy to insert the injection pipe 5 into the injection space 7 for the display material and discharge the display material into the glass plate gap B through the slit hole 5'as indicated by the arrow (->).

In addition, the Japanese Patent Application No. Sho 63-165820 (No.
2-087220) does not have the display material injection space 5, so there is a problem that the injection pipe 5 cannot be inserted quickly and easily. However, the present invention solves this problem, and the injection pipe 5 It also solves the problem that the broken fine pieces of the sealing material are easily mixed in the liquid when the display material is inserted and the display material is discharged.

This embodiment is applied to, for example, a light valve, and the glass plate 1,
The ITO conductive film is pre-patterned on the inner surface of the 1'and filled with a liquid in which a needle-like colloid made of dihydrozinconidine sulphate periodate as a display material is suspended in a dispersion medium and a stabilizer. The clear color pattern is displayed in the energized state. It is to be noted that glass beads having a diameter of 100 μm are scattered as spacers 4 ′ between the glass plates 1 to maintain the distance at 100 μm.

[Effect of device]

According to the present invention, the sealing material is firmly adhered to the glass substrate, and it can withstand the bending of the transparent substrate during manufacturing or use,
Further, it is possible to perform the injection of the display material extremely quickly and easily.
