Problems solved by technology

In order to reduce the thickness, it is necessary to reduce the distance between the package cover and the transparent substrate, but in this way, the package cover is easy to be bent due to external pressure, or the particles generated in the panel process are pressed to cause damage to the components on the transparent substrate
[0006] In addition, the two display panels 11 and 12 are manufactured through different processes, so the manufacturing process is complicated and time-consuming
Moreover, the two display panels 11 and 12 must be driven separately, which cannot save materials such as chips and flexible circuit boards, and increases the cost.
[0007] The existing double-sided display device is relatively thick and the process is complex, and its process requires the use of more materials such as integrated circuits (ICs) and flexible circuit boards (FPCs).

[0044] Please refer to Figure 3A , according to the first embodiment of the present invention, a first plan configuration diagram of a light emitting element. A plurality of upward light-emitting elements 22 and a plurality of downward light-emitting elements 23 are arranged on the substrate 21 in a chessboard pattern alternately, of course, they can also be arranged on the substrate 21 in strips. The upward light-emitting element 22 and the downward light-emitting element 23 can be electrically connected to the same driving element 25 to display the same picture on the front and back of the display device 20 .

[0045] Please refer to Figure 3B , according to the first embodiment of the present invention, the second plan configuration diagram of the light emitting element. The upward light-emitting element 22 is electrically connected to the driving element 25a, and the downward light-emitting element 23 is electrically connected to the driving element 25b, so as to indep...

Abstract

The invention relates to a dual-surface display, which comprises a basic plate, the first lighting element, the second lighting element and an upper cover. Wherein, two lighting elements are on the basic plate while the first lighting element has the first lighting direction and the second the lighting element near the first one has the second lighting direction; the upper cover is above the first and second lighting elements and is in the 1-100 microns distance from said lighting elements.

Description

technical field [0001] The invention relates to a double-sided display device, in particular to a double-sided organic electroluminescence display device which can prevent light-emitting elements from being damaged by external forces. Background technique [0002] The forms of electronic products are becoming more and more diversified, and the double-sided display function has become the main feature of the new generation of electronic products. For example, the double-sided display device inside the mobile phone can display the main function window of the mobile phone on one side, and display the time on the other side. Currently, double-sided display devices produced in the industry are usually formed by bonding two single-sided display panels, such as a liquid crystal display panel and an organic electroluminescent panel, or two organic electroluminescent panels. [0003] figure 1 It is an existing double-sided display device. The existing double-sided display device 1...
