Technical Field

[0001] The present invention belongs to the technical field of solar display, and more specifically, relates to a double-sided solar display device. Background Art

[0002] Most display devices on the market are mainly single-sided displays. When there is a need for double-sided independent display, only two display devices with the same size can be arranged back to back. Existing double-sided display devices generally have the problem of consuming a large amount of electricity. Limited by the existing battery technology, the thickness and outdoor power storage duration of double-sided display devices are restricted, and problems such as overheat protection resulting in shutdown and black screen are likely to occur during outdoor use. For existing double-sided display devices, each display screen has an independently set black glass absorption layer, and the light utilization rate of solar cells only reaches 30-50%. It is difficult to meet the long-term application requirements only through solar cells. Usually, a lithium battery is stacked on the basis of solar cells, which relatively increases the manufacturing cost and there is a risk of a greater impact on the service life of the display device due to long-term exposure to the sun, not meeting the requirements of mobile electronic products.
