Description

The present invention relates to a display panel mounting structure and a mounting method for mounting a flexible display panel on a curved mounting surface.

Conventionally, in order to attach a rigid display panel to a curved mounting surface, it has been necessary to process the display panel into a shape along the mounting surface in advance (for example, refer to Patent Document 1). However, there are various types of mounting surfaces, and when a display panel having rigidity is used, it is difficult to adjust the display panel along the mounting surface at the mounting site. Therefore, it is conceivable to use a flexible display panel.

JP, 2005-148716, A

However, even if the display panel itself has flexibility, if the engaging member for attaching the display panel to the mounting surface does not have flexibility and is provided on the entire rear surface of the display panel, the display will end up being displayed. Since the panel cannot be bent flexibly, it is difficult to mount the display panel along the mounting surface. Therefore, it is conceivable to disperse a plurality of engaging members on the back surface of the display panel.

On the other hand, when the plurality of engaging members are provided on the back surface of the display panel, the engaging members and the engaging receiving members are accurately positioned when the engaging receiving members that engage with the engaging members are attached to the mounting surface. If they cannot be aligned, the display panel cannot be mounted on the mounting surface. Further, the engagement receiving member has to be aligned in accordance with the radius of curvature and the shape of the attachment surface, and the workability of attaching the engagement receiving member is not good.

An object of the present invention is to provide a mounting structure and a mounting method for a display panel that can improve workability in mounting a display panel along a mounting surface of various shapes at a mounting site.

The display panel mounting structure of the present invention includes a display panel, a plurality of engaging members, a plurality of engaging receiving members, and a sheet member. The display panel has flexibility. The plurality of engaging members are provided on the back surface of the display panel. The plurality of engagement receiving members are respectively engageable with the plurality of engagement members. The sheet member is provided with a plurality of marks at the positions corresponding to the respective positions of the plurality of engaging members on the back surface of the display panel, the marks indicating the positions where the engaging receiving members are attached.

In this configuration, the engagement receiving member is attached to the attachment surface at the position marked on the sheet member with the sheet member attached to the attachment surface. Therefore, the operator can accurately and easily recognize the attachment location of the engagement receiving member for accurately aligning the engagement member and the engagement receiving member.

The display panel mounting method of the present invention includes a sticking step, a mounting step, and an engaging step. In the attaching step, a plurality of engagement receivers that are respectively engageable with the plurality of engagement members are provided at positions corresponding to respective positions on the back surface of the plurality of engagement members provided on the back surface of the flexible display panel. A sheet member having a plurality of marks indicating the positions where the members are attached is attached to the attachment surface of the display panel. In the attaching step, the plurality of engagement receiving members are attached to the places marked with the plurality of marks. In the engaging step, the plurality of engagement receiving members and the plurality of engaging members are engaged with each other.

In this configuration, the engagement receiving member is attached to the attachment surface at the position marked on the sheet member with the sheet member attached to the attachment surface. Therefore, the operator can accurately and easily recognize the attachment location of the engagement receiving member for accurately aligning the engagement member and the engagement receiving member.

According to the present invention, it is possible to improve the workability of mounting the display panel along the mounting surfaces of various shapes at the mounting site.
