Benefits of technology

Enables simple and efficient implementation of various hues, transmittance, and brightness within a single pixel, reducing manufacturing complexity and cost while improving light wavelength reflection and transmittance control.

Problems solved by technology

However, the electronic ink is limited because it is difficult to represent various colors since the color of the particles is set to specific colors.
The light transmittance tuning device according to the related art includes a mechanical shutter performing a function of tuning light transmission, etc., and as a result, has a complicated structure and too much manufacturing time and manufacturing costs are required.

first embodiment

[0154]FIG. 7 is a view conceptually illustrating a configuration of controlling inter-particle distances in accordance with a first mode of a display device of the present invention. Referring to FIG. 7, if no external electric field is applied, unit polarized solvent 710 near particles 720 having electric charges can be intensively arranged in the direction of the particles by interaction with the electric charges of the particles, and the unit polarized solvent 710 can be arranged more chaotically or randomly as its distance from the charged particles increases (See FIG. 7(a)). In addition, referring to FIG. 7, if an external electric field is applied, the unit polarized solvent 710 located in a region not affected by the electric charges of the particles 720 (i.e., a region far away from the particles 720) is re-arranged in the direction of the electric field and the charged particles 720 may be re-arranged by the affect of the rearranged solvent. That is, the unit polarized solv...

second embodiment

[0156]FIG. 8 is a view conceptually illustrating a configuration of controlling inter-particle distances in accordance with the first mode of the display device of the present invention. Referring to FIG. 8, if no external electric field is applied, particles 810 are not polarized (see FIG. 8(a)). If an external electric field is applied, the particles 810 can be electrically polarized due to the electrical polarization characteristic of the material in the particles 810. Accordingly, the particles 810 can be regularly arranged while maintaining a predetermined interval or space therebetween (see FIG. 8(b)).

[0157]In the first and second embodiments of the present invention, the greater the electrical polarization value of the solvent or particles, the higher the degree of interaction between the polarization regions 730 or between the polarized particles 810, thereby enabling the particles to be more regularly arranged. FIG. 8 shows the particles having no remnant polarization. Howe...

Abstract

In a display method or device according to one embodiment of the present invention, at least two of a photonic crystal reflection mode, a unique color reflection mode and a transmittance tuning mode may be implemented to be switched to each other within the same unit pixel. In addition, a machine readable storage medium recording a computer program performing the display method is provided.

Description

BACKGROUND OF THE INVENTION[0001]1. Technical Field[0002]The present invention relates to a display method and device. More particularly, the present invention relates to a display method and device implemented so as to switch at least two of a photonic crystal reflection mode, a unique color reflection mode and a transmittance tuning mode to each other within the same pixel.[0003]2. Description of the Related Art[0004]Recently, as the research and development of next-generation displays is actively being pursued, a variety of displays is being introduced. A typical example of the next-generation displays may include an electronic ink. The electronic ink is a display in which an electric field is applied to particles of specific colors (e.g., black and white) respectively having negative charges and positive charges to display the specific colors. Electronic ink has the advantages of low power consumption and flexible display. However, the electronic ink is limited because it is dif...
