| 20110068684 | ELECTROLUMINESCENT DISPLAY DEVICE - A color electroluminescent (EL) display device comprises a transparent substrate, and a transparent electrode arranged on the transparent substrate. The EL display also includes an electroluminescent layer arranged on the transparent electrode that comprises a plurality of pixel units. Each pixel unit comprises at least two regions comprising electroluminescent materials capable of emitting light of different colors. The EL display further comprises a plurality of opposing electrodes arranged on the electroluminescent layer. Each of the opposing electrodes cooperates with the transparent electrode to apply a voltage to one of the at least two regions of each pixel unit. | 03-24-2011 |
| 20110069093 | ELECTROPHORETIC DISPLAY DEVICE - An electrophoretic display device includes an electrophoretic ink layer, a plurality of pixel electrodes and a plurality of TFTs (thin film transistors) formed on a lower substrate. Each pixel electrode is connected between one TFT and the electrophoretic ink layer, first path terminals of all of the TFTs are connected to a power source driver, control terminals of all of the TFTs are connected to a gate driver. A transparent electrode is formed between the upper substrate and the electrophoretic ink layer. The electrophoretic ink layer includes a plurality of tubular cavities connected between the transparent electrode and the pixel electrodes, each tubular cavity contains a plurality of charged pigment particles. When a TFT is turned on by the gate driver, the source driver applies a voltage to the pixel electrode corresponding to the TFT, then driving the charged pigment particles to move and the tubular cavity displays corresponding color. | 03-24-2011 |
| 20110069372 | ELECTROPHORETIC DISPLAY - An electrophoretic paper device is provided. The electrophoretic paper device includes a plurality of pixel electrodes arranged on a lower substrate. The electrophoretic paper device also includes an upper substrate having a common electrode that covers an entire area corresponding to a display surface. The electrophoretic paper device further includes an electrophoretic ink layer, which includes a plurality of tubular cavities and each of the tubular cavities contains suspension fluid and a plurality of charged pigment particles dispersed in the suspension fluid. | 03-24-2011 |
| 20110069373 | ELECTROPHORETIC DISPLAY DEVICE - An electrophoretic display device includes pixel electrodes, a transparent electrode, and an electrophoretic ink layer including cavities. Each cavity is arranged between one of the pixel electrodes and the transparent electrode, and each cavity comprises suspension fluid, charged particles, and neutral particles, the charged particles and neutral particles being dispersed in the suspension fluid. The neutral particles are dispersed in the center of the cavities and substantially stationary, and the charged particles are capable of moving through the suspension fluid. Application of an electric field to a pixel electrode and the transparent electrode causes a migration of the charged particles of a cavity connected to the pixel electrode and a corresponding color becomes viewable. | 03-24-2011 |
| 20110095972 | ELECTROPHORETIC DISPLAY DEVICE - An electrophoretic display device includes pixel electrodes, a transparent electrode, and an electrophoretic ink layer. The electrophoretic ink layer includes a transparent film. Grooves are defined on the transparent film. Each groove is arranged between one of the pixel electrodes and the transparent electrode, and includes suspension fluid, and charged pigment particles dispersed in the suspension fluid. When application of an electric field between one of the pixel electrodes and the transparent electrode causes movement of the charged pigment particles of one of the grooves corresponding to the pixel electrode, and the groove displays a corresponding color. | 04-28-2011 |
| 20110148833 | ELECTROPHORETIC DISPLAY AND METHOD FOR ADJUSTTING DRIVING SETTINGS THEREOF - A method for adjusting driving waveforms in an electrophoretic display includes: measuring grey level of the electrophoretic display periodically; comparing the measured grey level with a standard grey level, selecting a driving waveform from pre-stored driving waveforms according to the current grey level and the standard grey level if the measured grey level is not equal to the standard grey level; and applying the selected driving waveform to achieve the standard grey level. The electrophoretic display is also provided. | 06-23-2011 |
