Problems solved by technology

The advantage of this method is that the cost is low, but its disadvantage is that if you want to change the pattern, you must erase and rewrite or replace another poster, and you cannot switch the pattern screen at will
The more advanced method is to use a liquid crystal display directly as a viewing board. The advantage of this method is that the liquid crystal display can display any pattern, and the screen can be switched at will; however, the disadvantage is that the liquid crystal display needs to continuously apply voltage to maintain the display. screen, consumes more power

Embodiment Construction

[0050] figure 1 A schematic cross-sectional view of a first embodiment of a display device of the present invention is shown, wherein the display device is in a first state. The display device 1 includes a first display element 10 , a first voltage input element 12 , a second display element 11 and a second voltage input element 13 .

[0051] The first display element 10 has a display area for displaying a bottom pattern. In this embodiment, the first display element 10 is a low power display (Low Power Display), such as a bistable display (Bistable Display). Preferably, the first display element 10 is an electronic paper. Viewed from a top view, the bottom pattern is a black and white pattern, which has a plurality of black pixels 101 and a plurality of white pixels 102 .

[0052] The first voltage input element 12 is electrically connected to the first display element 10 for inputting a first voltage to the first display element 10 to change the display of the bottom patt...

Abstract

The invention relates to a display device, which comprises a first display element, a first voltage input element, a second display element and a second voltage input element. The first display element displays a bottom pattern. The first voltage input element which is electrically connected with the first display element is applied for inputting a first voltage to the first display element so as to change the bottom pattern. The second display element which is located on the first display element is applied for matching the bottom pattern to display a color pattern. The second voltage input element which is electrically connected with the second display element is applied for inputting a second voltage to the second display element so as to change the color pattern. In this way, the pattern can be changed at will by only inputting smaller voltages.

Description

technical field [0001] The invention relates to a display device, in particular to a display device capable of switching between two display states. Background technique [0002] Existing billboards for advertising are usually handwritten or posted posters, which can only display a kind of pattern at a time. The advantage of this method is that the cost is low, but its disadvantage is that if you want to change the pattern, you must erase and rewrite it or replace another poster, and you cannot switch the pattern screen at will. The more advanced method is to use a liquid crystal display directly as a viewing board. The advantage of this method is that the liquid crystal display can display any pattern, and the screen can be switched at will; however, the disadvantage is that the liquid crystal display needs to continuously apply voltage to maintain the display. The screen will consume more power. [0003] Therefore, it is necessary to provide an innovative and progressive...
