Description

Display device

The present invention relates to an electronic device, and more particularly to a display device.

For the rapid advancement of the multimedia society, most of them benefit from the rapid development of semiconductor components or display devices. In terms of display elements, cathode display tubes (or cathode tubes, Cathode Ray Tubes, CRTs) have consistently dominated the display market due to their superior display quality and economy. However, CRTs have the problem of excessive volume and excessive energy consumption. For high image quality, low power consumption, thin mass production, low voltage driving, small size, etc., CRT-type displays obviously cannot achieve this requirement. In view of this, liquid crystal display (LCD) will have great advantages, and LCD has been widely used in small and medium-sized portable TVs, video phones, video recorders, notebook computers, and tables. Top-size displays, tablets, and projection color TVs.

For example, a conventional tablet computer includes a display module, a casing member and a light-transmitting plate. The outer casing member comprises a bottom plate and a ring-shaped side wall integrally formed with the bottom plate, and the bottom plate and the annular side wall form an accommodating space. The display module is disposed in the accommodating space of the outer casing member. The light transmissive plate is assembled on the outer casing member, so that the display module is covered by the light transmissive plate and the outer casing member.

However, in practice, in order to take into account the overall structural rigidity of the tablet computer, to avoid the tablet computer being easily deformed by the force, the thickness of the bottom plate of the outer casing member must be at least 1 cm or more. As a result, the design of the conventional housing member is not conducive to the development of the thinning of the tablet.

The present invention provides a display device for improving the design of a housing member of a conventional display device which is disadvantageous for the development of thinning of the electronic device.

The display device disclosed in the present invention comprises an outer frame, a plastic frame, a display module, a light transmissive plate and an inner frame. The outer frame includes a frame and a substrate attached to one side of the frame. The plastic frame is located on the substrate, and the frame surrounds the plastic frame. The plastic frame has a carrier plate and a ring-shaped side wall erected on the carrier plate. The carrier plate is adjacent to the substrate, and the carrier plate has a through hole. The display module is disposed on the carrying board, and the ring-shaped side wall surrounds the display module. The light-transmitting plate is attached to one side of the frame opposite to the substrate, and the light-transmitting plate is located on the display module. The inner frame covers the plastic frame and closes the through hole, and the substrate is attached to the inner frame.

According to the display device of the present invention, the frame and the substrate of the outer frame are two independent components, and the bottom plate of the inner frame closes the through hole, so that the bottom plate and the substrate can have a larger bonding area. . In view of such a display device, in addition to the material and thickness of the substrate can be appropriately selected to meet the requirements of the thin design, the bonding strength between the substrate and the substrate can be simultaneously considered.

The features, implementations, and utilities of the present invention are described in detail below with reference to the drawings.
