Problems solved by technology

At the same time, because the manual design does not design the driving waveform under all temperature conditions, it is only an approximate value within a certain range, so that the adaptation of the driving waveform to the external environment can only be unsatisfactory.

Abstract

The invention discloses a self generation method of a driving waveform for electrophoresis display equipment. The self generation method comprises calculating the luminance value of each gray scale; gradually increasing the positive voltage or negative voltage time length applied to a pixel electrode from the previous state to form a new driving waveform; driving the electrophoresis display equipment to display images and measure the luminance values; acquiring the luminance values and feeding back the luminance values to a control unit; determining whether the effect of the driving waveform is the required result by means of the control unit; if achieving the expected effect, saving the driving waveform and continuing operation to generate driving waveforms which are transformed from other states; and if not achieving the expected effect, generating a new driving waveform by continuously increasing the time length of positive voltage or negative voltage. The self generation method of a driving waveform for electrophoresis display equipment has the advantages of liberating the labor force and improving the work efficiency through automatic operation of the computer. The generated driving waveform is adaptive to the environment and hardware conditions so that the display effect is better. Compared with a traditional driving waveform, the high frequency driving mode enables human eyes to enjoy higher comfort degree.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a method for generating driving waveforms of electrophoretic display devices. Background technique [0002] Microcapsule electrophoretic display technology is currently the most mainstream electronic paper display technology on the market. Compared with other display technologies, it has the advantages of low energy consumption and low manufacturing cost. There are two kinds of charged particles, black and white, in the microcapsules. White particles are positively charged and black particles are negatively charged. When driven by voltages of different polarities, the black and white particles move under the action of the electric field force, resulting in various gray scales from black to white that can be observed by the human eye. [0003] The current design of the driving waveform required by the electrophoretic display device is done manually, the design process is cumber...
