摘要:
Disclosed are electrophoretic particles, a method of preparing the same, and an electrophoretic display using the same. The electrophoretic particle includes a coating layer, which includes a co-polymer of styrene and heterocyclic compound, and a pigment surrounded by the coating layer. The method includes polymerizing styrene on a surface of the electrophoretic particle and polymerizing styrene and a heterocyclic compound. The electrophoretic display includes the electrophoretic particles.
摘要:
A display apparatus having pixel areas defined on a substrate. First color pixels having a white color and second color pixels having a color different from that of the first color pixels are aligned in each pixel area in the form of a matrix. The second color pixels are adjacent to the first color pixels in the row and column directions.

A display panel includes first and second substrates. The first substrate includes a light blocking layer having an opening through the light blocking layer. The opening is arranged in a pixel area. The second substrate includes first and second transistors, first and second driving electrodes, and a shutter. The first transistor is turned on in response to a low level control voltage. The second transistor is electrically connected to the first transistor and is turned on in response to receiving a low level voltage from the first transistor. The first driving electrode is electrically connected to the first transistor, and the second driving electrode is electrically connected to the second transistor. The shutter exposes or covers the opening by moving to the first driving electrode or the second driving electrode according to the relative levels of voltages applied to the first and second driving electrodes.
摘要:
In a method for manufacturing a nanoparticle, a precursor (e.g., transition metal complex) mixed with polyethylene glycol (PEG) is thermally decomposed. A nanoparticle is formed from the thermal decomposition. PEG is cost effective and less toxic than chemicals that are conventionally used for nanoparticle production, so that costs for manufacturing the nanoparticle may be decreased. Further, PEG may be reused to produce more nanoparticles.
摘要:
The driving apparatus of a display device calculates a slope using a minimum gray, a maximum gray, a gray average of frame data in a current frame, and a gray average of frame data in a previous frame, and corrects and outputs the input frame data according to the slope, using frame data of one frame. As a result, a gray range of the input image signal can be extended, thereby improving visibility. Further, in a case of a motion picture, even when a difference of a gray range of images of adjacent frames is large, an original image is not distorted due to extension of a gray range. Also, even when noise is included in the input image signal, a gray range can be extended after removing the noise.
