JPH06273723A - Holding frame for glass lcd - Google Patents

Abstract

PURPOSE:To prevent a glass LCD from being easily broken by the holding frame where notch parts, through which four corners of the glass LCD can be exposed, are provided at four corners to prevent an external force from being concentrated to the glass LCD. CONSTITUTION:A glass LCD 1 is fixed on a printed board 3 with a holding frame 9, and this holding frame is made of a metal, a synthetic resin, or the like and consists of a rectangular frame body 10, a frame edge 11, and claws 6 provided in the lover end of the frame body 10. Notch parts 12 formed by cutting away triangular prisms are provided at four corners except the vicinity of the lower end of the frame body 10, and triangular through holes 13 are formed in corner parts of the frame edge 11 by these notch parts. When an external force of twist, bend, or the like is applied to the holding frame 9, the holding frame 9 is deformed in accordance with the strength of the external force by the elasticity of the metal or the synthetic resin, but, the external force does not act on four corners of the glass LCD 1 because four corners of the glass LCD 1 are exposed through the through holes 13 of notch parts 12 formed in the frame body 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device used as a display portion of various electronic devices, and more particularly to a glass LCD holding structure.

[0002]

2. Description of the Related Art A liquid crystal display device used as a display portion of various electronic devices is a kind of digital display, and in particular, a glass LCD (Liquid Crystal Display).
lay) is one in which a transparent liquid crystal material is usually enclosed between two glass plates, and the surface of each glass plate is provided with a transparent conductive film such as tin oxide or indium oxide.

Due to the nature of glass, the glass LCD lacks followability to external force such as twisting and bending, and is easily damaged by cracks, cracks and the like. Therefore, glass LCD easily
A frame that holds the glass LCD is attached to prevent damage.

A conventional glass LCD shown in FIG.
The holding frame will be described.

A glass LCD 1 is fixed on a printed circuit board 3 by a holding frame 2. The holding frame 2 is a rectangular frame body 4,
Frame edge 5, claw 6 provided at the lower end of the frame body 4 (in the figure, 4
Piece).

A mounting hole 7 is formed in the printed circuit board 3 so as to correspond to the claw 6, and the mounting hole 7 and the claw 6 can be fitted to each other.

As described above, the glass LCD 1 has a liquid crystal material enclosed between two glass plates.
A sealing frame 8 is provided around the periphery of the glass LCD 1 to seal the liquid crystal material (see the shaded portion in FIG. 2). The frame edge 5 is shaped so as to press the peripheral edge of the glass LCD with a required width over the entire circumference.

The material of the holding frame 2 is metal, synthetic resin or the like, and has elasticity such that it deforms in response to the magnitude of the external force when it is applied, and restores when the external force is removed.

[0009]

On the other hand, however, since the glass LCD 1 is fragile in material, the deformation allowance against external force is significantly smaller than that of the holding frame 2. Further, the holding frame 2 described above is the entire periphery of the glass LCD 1, that is, the glass LCD.
Since it has a shape to hold up to the four corners of No. 1, when the holding frame 2 is deformed by an external force such as twisting or bending, the glass LC
There is a problem that the external force is concentrated on the four corners of D1 and cracks, cracks or the like are generated at or near the four corners of the glass LCD 1.

In view of the above situation, the present invention is a glass LCD.
Holds the glass LCD so that the glass LCD is not easily broken or cracked even if the body of an electronic device in which the is mounted is deformed due to twisting or bending, or if it is impacted by falling. It is intended to provide a frame.

[0011]

The present invention is characterized in that cutouts are formed at the four corners of a frame so that the four corners of a glass LCD can be exposed.

[0012]

The notch formed at the four corners of the frame body of the holding frame of the glass LCD serves as an escape route for the external force applied to the glass LCD, and the external force is not concentrated on the glass LCD.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

1 to 3, the same parts as those shown in FIG. 4 are designated by the same reference numerals.

The glass LCD 1 is fixed on the printed circuit board 3 by a holding frame 9. The holding frame 9 is made of metal, synthetic resin, or the like, and includes a rectangular frame body 10, a frame edge 11, and a claw 6 provided at the lower end of the frame body 10.

Notch portions 12 are formed in the four corners of the frame 10 except the vicinity of the lower end so as to cut out a triangular prism.

The corner portion of the frame edge 11 is in a state in which a triangular through hole 13 is formed by the cutout portion 12. Further, the frame edge 11 is shaped so as to press the peripheral edges of the glass LCD 1 excluding the four corners.

The holding frame 9 is fixed on the printed circuit board 3 by fitting the claws 6 into the mounting holes 7 formed in the printed circuit board 3.

The operation will be described below.

In order to fix the glass LCD 1 to the printed board 3, the holding frame 9 is fitted on the glass LCD 1. Since the cutouts 12 are formed at the four corners of the frame body 10 of the holding frame 9, the four corners of the glass LCD 1 are exposed from the through holes 13 as shown in FIGS.

When an external force such as twisting or bending is applied to the holding frame 9, the holding frame 9 is deformed according to the magnitude of the external force due to the elasticity of metal or synthetic resin. The glass LC
Since the four corners of D1 are exposed from the through holes 13 of the notch 12 formed in the frame body 10, the glass LCD 1
No external force acts on the four corners.

Thus, the external force is not concentrated on the four corners of the glass LCD 1 and is not easily broken.

In this embodiment, the frame body 10 of the holding frame 9 is formed with the notch 12 which is formed by cutting a triangular prism. However, the four corners of the glass LCD 1 are exposed and serve as a escape route for external force. It goes without saying that, if there is any, a notch may be formed, for example, by cutting a three-sided pyramid.

[0024]

As described above, according to the present invention, the external force is not concentrated on the glass LCD even if the main body of an electronic device or the like on which the glass LCD is mounted is twisted or bent, or is given a shock by dropping. The frame can prevent the glass LCD from being easily damaged.
