Problems solved by technology

The disadvantage is that because the bistable display also has certain optical reflections in the dark state (the second stable state of the display), the actual effect of the printed pattern cannot be completely consistent with the background color of the dark state of the display, resulting in the display being in the dark state. Sometimes the printed pattern can be faintly displayed, and the printed pattern has reliability risks such as damage and peeling
The second method is to lead a separate pattern electrode in the display, together with the background electrode and the common electrode of the display, to form a three-electrode input driving method, as shown in Figure 1(b). The disadvantage is that although it can improve the pattern display effect, but due to an additional set of drive circuits, it is not only incompatible with the previous drive circuit, but also increases the cost of the drive circuit

Abstract

Provided is a bistable state displayer. The displayer includes an inner box, and the inner box is composed of a first baseplate, a second baseplate and a box body encircling the space between the first baseplate and the second baseplate, and the space is injected with a bistable state display material. One or more of a common electrode conduction layer, a pattern conduction layer and a backgroundconduction layer are formed on the first baseplate and / or the second baseplate in the inner box separately. The common electrode conduction layer is led to the exterior of the inner box through commonelectrodes, the pattern conduction layer is led to the exterior of the inner box through pattern electrodes, and the background conduction layer is led to the exterior of the inner box through background electrodes.

Description

technical field [0001] The invention relates to a bistable display and a driving method thereof, in particular to a bistable display driven by two electrodes and a driving method thereof. Background technique [0002] There is a display application in the electrical switch protection circuit. When the circuit system fails, the display can indicate the type of fault, and this indication state can be maintained when the power is off, that is, the display can also keep displaying in the absence of power supply. pattern, we call this kind of display a bistable display. Taking the entire display plane of the bistable display as a pixel, and drawing out two electrodes, it can be used as a bistable indicator light. Because it does not require electricity to maintain the indication, it has high practicality in electrical switch indication. value. As a functional extension of this display, we can print patterns on the display to make a bistable indicator light with specific meaning...
