The invention relates to a display.

With the trend toward lighter electronic products and the transmission of a large amount of information and images, people are increasingly demanding the lightness and image quality of flat-panel displays. Since the development of Organic Light Emitting Diode (OLED) components, it has attracted countless people to invest in the research and mass production of OLED displays. It has been regarded as a Thin Film Transistor Liquid Crystal Display (Thin Film Transistor Liquid Crystal Display, After TFT LCD), one of the most promising flat display technologies in the future.

The reason why OLED is favored is not only self-illumination, high response speed (1us), power saving (power consumption is only one-third of TFT LCD), wide viewing angle (180 degrees), wide color gamut (NTSC 100% or more), With low operating voltage (3-10V) and high contrast (up to 10 ⁴ :1), it is more important that it is light and thin (panel thickness can be less than 1mm). It is easy to use with self-illumination and simplified display structure. Achieving the characteristics of a transparent display, so it can be applied to a new generation of transparent display panels.

The transparent display panel allows a display surface to simultaneously allow light from the outside In addition to beam penetration, images can be formed by emitting image beams from pixels on the display panel. In order to achieve the above effects, the conventional transparent display panel often has a plurality of openings formed in the display panel, and a display pixel capable of emitting an image beam is disposed between the openings, so that the user can simultaneously view through the openings. To the image behind the display panel, you can also see the image displayed by the pixels between the openings. However, the above-mentioned openings also cause the light beam from the outside to be diffracted, thereby allowing the user to see the blurred, poor rear penetration image.

1A is a schematic diagram of a display in accordance with a first embodiment of the present invention. It is to be noted that the pixels and sub-pixels shown in the following figures relating to the description of the embodiments of the present invention are used to clearly illustrate the between the apertures and the pixels in the embodiment of the present invention. The configuration relationship is not intended to limit the shape, number, and size of each pixel and sub-pixel. Referring to FIG. 1A, in a first embodiment of the present invention, the display 100A includes a plurality of display units 110A and a plurality of openings 140. Each of the display units 110A includes a light transmissive area 120 and a non-transparent area 122. The non-transparent area 122 described herein refers to an area other than the light transmissive area 120 of the display unit 110A, and includes other translucent or The non-transparent element is, for example, a thin film transistor (TFT), a region of a capacitor or a wire arrangement.

The apertures are adapted to form a partial overlap of projections in one direction and to disrupt periodic diffraction to provide a clear, good transmissive image. In other words, under the same opening 140 circumference, the openings 140 satisfying the above range can have a larger opening 140 area because of having the shape of these non-quadrilaterals, that is, can provide good light transmission. effectiveness. On the other hand, by arranging the long axes of the elliptical openings 140 along the direction d2 while the partial projection amounts in the direction d2 overlap each other, the fixed opening frequency in the space is destroyed.

At the same time, since the openings 148A, 148C have non-quadrilateral-like openings 148A, the edge diffraction phenomenon can be reduced to provide a good picture. Referring to FIG. 3G, in another embodiment of the present invention, the opening may be composed of a circular opening 148A and a quadrangular opening 148D, wherein the opening 148D is rotated compared to the opening 148B. An angle reconfiguration further increases the degrees of freedom that the first sub-pixel 135A, the second sub-pixel 135B, and the third sub-pixel 135C of the display units 110I of the display can be configured, and the openings 148A and 148D are The overlapping regions K16, K17 projected in the direction d1 and the direction d2 are thus also increased. In the following, while the aperture configuration in other embodiments is explained, since the configuration of the sub-pixels is similar to the first sub-pixels 133A, 135A, the second sub-pixels 133B, 135B, and the third sub-pixels 133C, 135C described above, Therefore, the configuration relationship about these sub-pixels will not be repeated.

Referring to FIG. 3H, in another embodiment of the present invention, the opening may be composed of a circular opening 148A and a quadrangular opening 148E, wherein the opening 148E has an arc angle, thereby reducing the edge thereof. The length is reduced to reduce the edge diffraction effect, while the projections of the openings 148A, 148E in the direction d1 have an overlap region K18, and the portion projection in the direction d2 has an overlap region K19.

4A to 4C are schematic diagrams showing the opening of the display of the prior art and the image observation of the light source after passing through the opening. 4D is a schematic view showing the opening of the display and an image observation view of the light source after passing through the opening. 4A to 4D are schematic views showing different openings of the display at a pixel aperture ratio of 55%. The lower left figure shows the original actual observed image of the illuminating image without passing through the opening, and the lower right figure shows the actual observed image after the opening of each display. From the actual observed image, the aperture pattern according to an embodiment of the present invention can be verified, and the light beam penetrating through the apertures 420D can be prevented from generating excessive edge diffraction as compared with the prior art.

As can be seen from the above and FIGS. 4A to 4D, the display of the embodiment of the present invention can have a smaller diffraction width in any direction when it has the configuration of the opening 420D of the display unit 410D. That is, the opening 420D of the display of the embodiment of the present invention is in accordance with The degree of edge diffraction is slightly smaller than that of the respective openings 420A, 420B, 420C of the display units 410A, 410B, 410C of the prior art display.

In summary, the display provided by the embodiment of the present invention overlaps the projections in the second direction by overlapping the openings in the first direction, and can fix the frequency by reducing the opening in the space. Appears to reduce the diffraction caused by the edge of the opening, while maintaining a sufficient aperture ratio, so that the image through these openings is more clear, so that the background seen by the user through the opening is more clear. That is to say, the circular type hole can reduce the diffraction effect produced by the edge of the opening, and the overlapping projection of the opening can provide different spatial frequency matching, and the diffraction effect can be broken to destroy the diffraction addition in the fixed direction. On the other hand, at least one opening is a non-quadrilateral type and conforms to It can reduce the diffraction caused by the edge of the opening, while maintaining a sufficient aperture ratio, so that the image penetrating these openings is more clear. In this way, the display can not only provide a display screen, but also the user can clearly see the scene behind it through the display.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any one of ordinary skill in the art can make some changes and refinements without departing from the spirit and scope of the present invention. The scope of the invention is defined by the scope of the appended claims.
