Embodiment 1

[0058] Such as Figure 4A and Figure 4B As shown, the embodiment of the present invention provides a display device 1 , including: a flat display panel 11 and a light deflector 12 .

[0059] Among them, the reason why the display panel 11 is said to be flat is to distinguish it from the curved display screen, indicating that the two surfaces of the display panel 11 in this embodiment (that is, the display surface 11a and the back surface 11b opposite to the display panel) are both plane, and usually they are almost parallel.

[0060] Preferably, in this embodiment, the light emitting direction of the display panel 11 is perpendicular to the surface of the display panel. That is to say, the light emitted from the display panel 11 is mainly emitted from the display surface 11 a along a direction (direction A in the figure) perpendicular to the panel surface of the display panel. The reason for emphasizing "mainly" is that there are often errors between facts and theories. In...

Embodiment 2

[0086]The embodiment of the present invention provides a display device, focusing on the description of the structure of the display panel, which can emit vertical light; for the structure of the light deflector, you can refer to Embodiment 1, which will not be repeated in this embodiment .

[0087] As described in Embodiment 1, there are various types of display panels 11 . But no matter what kind of display panel you can refer to Figure 7 , including: a first substrate 111 and a second substrate 112 arranged oppositely and in parallel. A pixel structure (the part between 112 and 111 in the illustration) that can realize display is usually arranged between the two substrates. In this embodiment, because the pixel structure has little connection with the invention point of the present invention, it does not Not drawn in detail. The material of the substrate may be transparent glass or the like. In order to clearly describe the solution, in this embodiment, it is defined t...

Embodiment 3

[0136] As mentioned in the second embodiment, the passive display panel cannot emit light by itself, and needs to rely on the light emitted by the backlight module to realize display. In the second embodiment, a light correction unit is added to the existing passive display panel, so as to correct the light entering the passive display panel into a vertical light, which is emitted from the passive display panel.

[0137] In this embodiment, a new idea is provided for how to make the passive display panel emit vertical light. Specifically, without changing the structure of the original passive display panel, a light correction unit is added to the original backlight module so that the backlight module can emit vertical light. At this time, the influence of the passive display panel on the light transmission direction is ignored. Thus, the vertical light is emitted from the passive display panel.

[0138] can refer to Figure 19 , this embodiment provides a display device, inc...

Abstract

The invention discloses a display device and relates to the technical field of display. The display device basically reaches a curved-surface display effect under the condition that physical bending is not carried out. The display device comprises a plane-shaped display panel and a light deflection device, wherein the light deflection device is located in the light outgoing direction of the display panel; the light deflection device is used for converging outgoing light of the display panel toward a central plane; and the central plane is vertical to the display panel and passes through a vertical middle line of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] Displays in the prior art are mostly flat panel displays. Such as figure 1 As shown, assuming that the viewer watches the program directly in front of the flat display, the distance between the viewer and the center of the screen (L1) and the distance between the viewer and the two sides of the screen (L2) are not equal, which makes the viewer in the When viewing, the brightness of the image presented on both sides of the screen enters the human eye along an oblique direction (that is, not perpendicular to the display screen). Usually in this case, the viewer can receive the peak brightness emitted by the center of the screen, however, they cannot receive the peak brightness emitted by the two sides of the screen, and only receive relatively weak brightness emitted by the two sides of the screen, which causes the viewer t...
