Embodiment

[0029] A driving waveform debugging method for a three-color electronic paper module, comprising the following steps:

[0030] (1) if figure 1 As shown, determine the voltage value of the common pole Vcom 1: connect the three-color electronic group module 4 to the control board. The control board is an existing technology, and it will not be shown here. Detection equipment 3, detection equipment 3 such as a multimeter, set the Vcom 1 pin to be suspended, and control the screen to alternately update the full-screen black and full-screen white, repeat several cycles, observe and record the voltage value displayed by the multimeter when the black and white screen is switched, take The average value is the voltage value of Vcom 1;

[0031] (2) Determine the main driving frame: the main driving frame includes black main driving frame, white main driving frame and red main driving frame, respectively use black screen standard test waveform, white screen standard test waveform and r...

Abstract

The invention provides a method for debugging the driving waveform of a three-color electronic paper module, and the method herein has the characteristics of excellent universality, and excellent comparison and display effects. The method is characterized in that the method includes the following steps: 1. determining master driving frames: driving the three-color electronic paper module by usingblack / white / red picture standard test waveforms, and separately reading the black, white and red optical values of a test picture under three kinds of standard test waveforms by using an optical tester, separately comparing the black, white and red optical values with a standard black L*value, a standard white L* value, and a standard red L* value and a* value, obtaining a standard test waveform that meets optical requirements and obtaining a black / white / red master driving frame of the three-color electronic paper module; 2. determining DC balance frames: separately based on the black master driving frame, the white master driving frame and the red master driving frame, determining the DC balance frames corresponding to the black master driving frame, the white master driving frame and thered master driving frame; and 3. determining driving waveforms which include the DC balance frames that perform first driving and the black master driving frame, the white master driving frame and the red master driving frame that perform follow-up driving.

Description

technical field [0001] The invention relates to the technical field of electronic paper, in particular to a driving waveform debugging method of a three-color electronic paper module. Background technique [0002] Electronic paper is a display screen made using electrophoretic display technology, which achieves the effect of displaying images by continuously applying a driving waveform voltage to each pixel point through a driving IC. Three-color electronic paper refers to the encapsulation of black, white, and red charged particles in the same microcapsule structure, and the ups and downs of black, white, and red particles with different charges are controlled by an external electric field to display the three-color display effect of black, white, and red. At present, there is no universal driving waveform designed for the three-color e-paper module. Usually, a set of driving waveforms must be updated for different batches of products, and the contrast is also poor, and the...
