Problems solved by technology

However, due to the transparent display in the see-through area and unlike the display area covered by color resistance or polarizers, it is difficult to detect dust, and when dust enters the see-through area of ​​the display, the dust will cover part of the physical image and reduce the The display quality of the see-through area

Embodiment Construction

[0045] Please refer to figure 1 . figure 1 is a schematic cross-sectional view of the display device according to the first embodiment of the present invention.

[0046] The display device 10 of this embodiment includes a display panel 100 , a back plate 200 , a light guide plate 300 , a dust blocking structure 400 , an optical film 500 and a reflective film 600 .

[0047] The display panel 100 has a display area 140 and at least one see-through area 150 . The display area 140 surrounds the see-through area 150 . In detail, the display panel 100 located in the display area 140 has red color resistance, green color resistance and blue color resistance to present digital images. The display panel 100 located in the see-through area 150 has no color resistance and can present the color and brightness of the light source. If a physical picture appears in the see-through area 150 , the picture of the real picture can be clearly seen through. In this embodiment and other embodim...

Abstract

A display device comprises a display panel, a back plate, a light guide plate and a dust barrier structure. The display panel has a display area and at least a perspective area, and the display area surrounds the perspective area. The back plate has at least a first opening. The position of the first opening corresponds to the position of the perspective area. The light guide plate is disposed between the display panel and the back plate. The dust barrier structure includes a first body. The first body is disposed on a side, toward or away from the display panel, of the light guide plate. The first body has a first outer side surface. An orthographic projection area of the perspective area to the light guide plate falls within the surrounding scope of the first outer side surface.

Description

technical field [0001] The invention relates to a display device, in particular to a display device with dust blocking effect. Background technique [0002] The display can be divided into a display without a see-through area and a display with a see-through area according to structural differences. A display without a see-through area is, for example, a laptop screen or a TV screen, which is mainly used to display digital images. A display with a see-through area is, for example, a display screen on a slot machine. In addition to using the display area to display digital images, it also has the function of using the see-through area to see through physical images. However, due to the transparent display in the see-through area and unlike the display area covered by color resistance or polarizers, it is not easy to detect dust, and when dust enters the see-through area of ​​the display, the dust will cover part of the physical image and reduce the The display quality of th...
