Problems solved by technology

However, the use of color filters will lead to poor light utilization efficiency of the electrophoretic display device, which will reduce the brightness, contrast and color saturation of the electrophoretic display device
[0004] It can be seen that the above-mentioned existing electrophoretic display device obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem

Embodiment Construction

[0040] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the pixel structure and sub-pixel structure of the color electrophoretic display device proposed according to the present invention are specifically implemented below in conjunction with the drawings and preferred embodiments. Mode, structure, feature and effect thereof are as follows in detail.

[0041] The swimming speed of charged particles in solution can be expressed by the following formula

[0042] m=q / 6πγη,

[0043] Where m is the swimming velocity of the charged particles in the solution, q is the charge amount of the charged particles, γ is the particle size of the charged particles, and η is the solution viscosity. It can be seen from the above formula that the swimming speed of charged particles in solution is inversely proportional to the particle size of charged particles, that is, the larger the particle size of charged p...

Abstract

The invention relates to a pixel structure and a sub-pixel structure of a color electrophoresis display device. The sub-pixel structure of the color electrophoresis display device comprises a drive unit, a display unit and a transparent electrode, wherein the display unit is configured on the drive unit, the transparent electrode is configured on the display unit, the display unit comprises a plurality of first charged particles and a plurality of second charged particles, the color of the first charged particles is different from that of the second charged particles, the particle diameter ofthe first charged particles is greater than that of the second charged particles and the first charged particles and the second charged particles have the same electrical property. The sub-pixel structure of the color electrophoresis display device has higher light utilization efficiency.

Description

technical field [0001] The present invention relates to an electrophoretic display device (electrophoretic display), in particular to a pixel structure (pixel structure) and a sub-pixel (sub-pixel) structure of a color electrophoretic display device. Background technique [0002] With the advancement of flat display technology and the advantages of light weight, small size and power saving of flat display devices, flat display devices have become more and more popular. Common flat panel display devices include liquid crystal display (liquid crystal display, LCD), plasma display device (plasma display panel, PDP), organic light emitting diode display (organic light emitting diode display, OLED display) and electrophoretic display device (electrophoretic display, EPD), etc., where the electrophoretic display device does not have a light source, so compared with other flat-panel display devices, the electrophoretic display device has the advantage of saving power. [0003] The...
