Problems solved by technology

In an ideal situation, one grayscale can be divided into one frame time, so when the frame rate is 50 Hz, only 16 grayscales from grayscale 0 to grayscale 15 can be separated, and more grayscales cannot be displayed. , causing the display image quality to fail to improve
[0005] Therefore, it is necessary to propose a solution to the problem that the above-mentioned electrophoretic display cannot display higher gray scale numbers

Abstract

The invention discloses an electrophoresis type display and a drive method thereof. The electrophoresis type display comprises a plurality of pixels, a first electrode layer, a second electrode layer, a driving voltage generation unit and an electrophoresis layer arranged between the first electrode layer and the second electrode layer. The driving voltage generation unit is capable of supplying a plurality of sets of different driving voltages so as to drive charged particles in the electrophoresis layer; and therefore, the gray scale number displayed by the electrophoresis type display can be increased.

Description

technical field [0001] The present invention relates to an electrophoretic display, in particular to an electrophoretic display and its driving method. Background technique [0002] see figure 1 , is to illustrate the display principle of the electrophoretic display (Electro Phoretic Display). The electrophoretic layer 50 for displaying images is sealed between two films (Film) 120 . The electrophoretic layer 50 includes a plurality of charged particles 100 and a solution 110 in which the charged particles 100 are suspended. The display principle of the electrophoretic layer 50 is to drive the charged particles 100 suspended in the solution 110 by applying an external electric field to a first electrode 130 and a second electrode 140, so that the charged particles 100 change their positions to display different gray scales. [0003] Please also see figure 2 and image 3 , figure 2 It is a graph showing the driving voltage time of the electrophoretic display and the c...
