Embodiment Construction

[0023] The principles and features of the present invention are described below, and the examples are only used to explain the present invention, but not to limit the scope of the present invention.

[0024] like figure 2 As shown, this embodiment relates to a waveform debugging method for shortening the refresh time of black, red and white. When debugging the driving voltage waveform, a voltage balance area (Group1), a flickering area (Group2, Group4, Group6, Group8) and Display area (Group3, Group5, Group7, Group9, Group10), the flashing area and the display area are alternately distributed, including the following steps:

[0025] Step 1: In the voltage balance area, neutralize the voltage by giving the charged particles a voltage opposite to its own voltage;

[0026] Step 2: In the flickering area, the charged particles are first driven with high voltage, at this time the display screen is close to the black screen, and then given the low voltage drive, at this time the d...

Abstract

The invention discloses a waveform debugging method for shortening the refresh time of black, red and white three colors, which includes a voltage balance area, a flickering area and a display area, and the display areas in the flickering area are alternately distributed. When debugging the voltage waveform, the following steps are included: Step 1: In the voltage balance area, neutralize the voltage by giving the charged particles a voltage opposite to its own voltage polarity; Step 2: In the flickering area, first give the charged particles a high voltage drive, then give a low voltage drive, and then give a high voltage drive. Voltage drive, finally give low voltage drive, and end after many cycles; Step 3: Give high voltage drive to the white waveform in the display area to form a black picture, give low voltage drive to black and red waveforms to form a white picture, and end the display area, the present invention The beneficial effect is that the flashing area is driven in a multi-stage manner in a short period of time, the flashing area and the display area cycle alternately, and the final color is displayed in the display area. The refresh time of this driving method is short.

Description

technical field [0001] The invention relates to the technical field of electronic paper, in particular to a waveform debugging method for shortening the refresh time of black, red and white. Background technique [0002] Electronic paper is a display screen made of electrophoretic display technology, which achieves the effect of displaying images by continuously applying the voltage of the driving waveform to each pixel by the driving IC. Two-color electronic paper encapsulates black and white charged particles in the same capsule structure, and three-color electronic paper refers to three-color charged particles, such as black and white red or black and white yellow, are encapsulated in the same microcup structure, and different charges are controlled by an external electric field. The black, white and red particles move up and down to show the display effect of black, white and red. [0003] At present, when some EPD (electronic price tag) three-color module products such...
