20100207853 | ELECTRODES FOR USE IN DISPLAYS - A liquid crystal display (LCD) is provided having a discontinuous electrode. In certain embodiments, finger- or slit-like extensions of the discontinuous electrode may be shaped to reduce or eliminate disclinations of liquid crystals within a pixel aperture used to transmit light, where the liquid crystals are oriented in response to an electric field generated using the discontinuous electrode. Similarly, in other embodiments, the different portions of the discontinuous electrode may be lengthened to extend under an opaque mask or may not be linked at one end to reduce or eliminate the disclinations. | 08-19-2010 |
20100207854 | PLACEMENT AND SHAPE OF ELECTRODES FOR USE IN DISPLAYS - A liquid crystal display (LCD) is provided having a discontinuous electrode. In certain embodiments, different portions (such as finger- or slit-like extensions) of the discontinuous electrode may be at different depths relative to one another and/or may be of different widths relative to one another. Similarly, in other embodiments, the different portions of the discontinuous electrode may be spaced apart in a non-uniform manner. | 08-19-2010 |
20100207857 | Undulating Electrodes for Improved Viewing Angle and Color Shift - The present disclosure generally provides for a variety of multi-domain pixel configurations that may be implemented in the unit pixels of an LCD display device, such as a fringe field switching LCD display panel. An LCD display device utilizing one or more of the presently disclosed techniques disclosed herein may exhibit improved display properties, such as viewing angle, color shift, and transmittance properties, relative to those exhibited by conventional multi-domain designs. | 08-19-2010 |
20100207858 | LCD Pixel Design Varying by Color - A liquid crystal display (LCD) having a plurality of pixels is provided. In one embodiment, the pixels of the LCD each include common and pixel electrodes formed on an insulating layer, and a liquid crystal layer responsive to electric fields generated by the electrodes. The plurality of pixels may include two or more sets of pixels each configured to transmit light of a different color, and the pixel electrodes of one set of pixels may be configured differently from those of another set. In other embodiments, the sizes of the pixels may differ. Various additional devices and methods are also provided. | 08-19-2010 |
20100207860 | VIA DESIGN FOR USE IN DISPLAYS - A liquid crystal display (LCD) is provided having transistors disposed within via holes having elongated (e.g., rectangular or oval) contact areas. The use of via holes having elongated contact areas allows an opaque mask defining an aperture for light transmission to be lengthened, thereby increasing the overall area of the aperture. The increase in the area of the aperture may increase the amount of light that can pass through the aperture. | 08-19-2010 |
20100207862 | Pseudo Multi-Domain Design for Improved Viewing Angle and Color Shift - Aspects of the present disclosure relate to single-domain electrode configurations that may be implemented in the unit pixels of a LCD device, such as a fringe field switching (FFS) LCD, to provide a “pseudo-multi-domain” effect, wherein the benefits of both conventional single-domain and multi-domain pixel configuration devices are retained. In accordance with aspects of the present technique, single-domain unit pixels are angled or tilted in differing directions with respect to a vertical axis of the LCD panel (e.g., y-axis) to provide an alternating and/or periodic arrangement of different-angled pixel electrodes along each scanning line, data line, or a combination of both scanning and data lines. In this manner, the transmittance rates of conventional single-domain LCD panels may be retained while providing for improved viewing angle and color shift properties typical of conventional multi-domain LCD panels. | 08-19-2010 |
20100208179 | Pixel Black Mask Design and Formation Technique - A display panel is provided having a first substrate including an electrode configured to generate an electric field and a second substrate including a black mask. The black mask includes an aperture configured to enable light to be transmitted through the aperture, wherein the aperture is at least substantially rectangular and includes corners that are not substantially chamfered. The display panel also includes liquid crystal disposed between the first and second substrates and configured to facilitate passage of light through the display panel in response to the electric field. | 08-19-2010 |
20100245224 | LCD ELECTRODE ARRANGEMENT - Systems, devices, and methods for reducing direct current bias and/or enabling a simplified manner of polarity inversion in liquid crystal display (LCD) devices are provided. In accordance with one embodiment, a device may include a processor, a memory device, and a liquid crystal display having a pixel array including rows and columns of pixels. Each pixel of the pixel array may include a pixel electrode separated from a common electrode by a dielectric passivation layer, and may include a transistor to provide a data signal when the transistor is activated. The pixel array is configured such that a neutral amount of direct current bias is generated on the passivation layer when each row of pixels is activated. The common electrodes of certain pixels may be disposed above their respective pixel electrodes, while the common electrodes of certain other pixels may be disposed below their respective pixel electrodes. | 09-30-2010 |
20100245723 | LCD PANEL HAVING IMPROVED RESPONSE - A liquid crystal display (LCD) having a liquid crystal layer is provided. In one embodiment, the liquid crystal layer includes a nematic liquid crystal material having liquid crystal molecules in an untwisted state. A chiral dopant is dispersed within the liquid crystal layer and configured to bias the liquid crystal molecules toward a twisted state. Furthermore, a polymer network is disposed among the liquid crystal molecules and configured to bias the liquid crystal molecules toward the untwisted state. Various additional devices and methods are also provided. | 09-30-2010 |
20120162156 | SYSTEM AND METHOD TO IMPROVE IMAGE EDGE DISCOLORATION - Present techniques involve methods and systems for reducing edge discoloration in a display. In one embodiment, the first and last columns of a display are dimmed by adjusting a black mask or reducing transmittance of the relevant pixels. Further, the first and last columns of a display may be entirely covered by the black mask. In some embodiments, using a coupling extrusion on a neighboring sub-pixel can be used to control the coupling between the neighboring sub-pixels to reduce edge discoloration. Display software may also be used to reduce edge discoloration. For example, software may automatically reduce the brightness of the first and last column. In some embodiments, software may be used to detect edges of objects within the display area. Edges of an object are detected, and the last sub-pixel of the background and/or the first sub-pixel of the object are compensated. | 06-28-2012 |
