| 20090153774 | BACK LIGHT MODULE AND LIQUID CRYSTAL DISPLAY - A liquid crystal display (LCD) including an LCD panel and a back light module is provided. The back light module is disposed below the LCD panel. The back light module includes a planar light source, a reflective polarized light enhancement film, a first prism film and a λ/4 phase retardation film. The planar light source is disposed below the LCD panel, while the reflective polarized light enhancement film is disposed between the LCD panel and the planar light source. The first prism film is disposed between the reflective polarized light enhancement film and the planar light source. Besides, the λ/4 phase retardation film is disposed between the reflective polarized light enhancement film and the first prism film. The back light module has a relatively high light utilization rate, and the LCD has favorable display luminance. | 06-18-2009 |
| 20090213092 | TOUCH DISPLAY, LIQUID CRYSTAL DISPLAY WITH A BUILT-IN TOUCH PANEL - A liquid crystal display (LCD) with a built-in touch panel includes an LCD unit, a touch panel and a second polarized plate. The LCD unit includes a lower substrate, an upper substrate, a liquid crystal layer and a first polarized plate. The upper substrate is disposed opposite to the lower substrate, and the liquid crystal layer is disposed between the lower substrate and the upper substrate. The first polarized plate is disposed on the lower substrate and has a first polarized direction. The touch panel is disposed opposite to the LCD unit. The second polarized plate having a second polarized direction is disposed on the touch panel and located between the LCD unit and the touch panel. An intensity of a reflected light occurred in the LCD with the built-in touch panel is relatively low, so that good contrast and visibility are obtained. | 08-27-2009 |
| 20090279022 | MICRO REFLECTION-TYPE LIQUID CRYSTAL DISPLAY - The present invention discloses a micro reflection-type liquid crystal display (LCD) using a step difference resulting from the existing array processing and a liquid crystal cell comprising liquid crystal molecules being aligned in parallel to perform optical compensation according to the difference between optical slow axes on orthogonal optical compensation films. In a compensation system comprising orthogonal polarizers, an equivalent retardation is acquired according to the differences between the slow axes on the optical compensation films and the alignment orientation of the liquid crystal molecules when the liquid crystal cell is driven or not to determine the optimal dark/bright state. Moreover, the optimal dark state can be achieved at the same driving voltage under both the reflection mode and the transmission mode. Thereby, the present invention achieves improved image contrast and reflectivity without additional processing steps. | 11-12-2009 |
| 20100201924 | LIQUID CRYSTAL DISPLAY - A normally-black mode liquid crystal display includes a first and a second transparent substrate facing to each other, a liquid crystal layer, a first and a second polarizer, a first and a second half wave plate, and a first and a second positive C plate. The liquid crystal layer is interposed between the first and the second transparent substrate. The first polarizer is disposed on a side of the first transparent substrate opposite the liquid crystal layer, while the second polarizer is disposed on a side of the second transparent substrate opposite the liquid crystal layer. The first half wave plate is provided between the first transparent substrate and the first polarizer, and the second half wave plate is provided between the second transparent substrate and the second polarizer. The first positive C plate is disposed between the first half wave plate and the first transparent substrate, and the second positive C plate is disposed between the second half wave plate and the second transparent substrate. | 08-12-2010 |
| 20100214264 | TOUCH PANEL AND TOUCH DISPLAY PANEL - A touch display panel and a touch panel therein are provided. The touch panel includes a first transparent supporter plate, a second transparent supporter plate, and a touch module. The second transparent supporter plate and the touch module are disposed over the first transparent supporter plate. The first transparent supporter plate and the second transparent supporter plate have optical anisotropy. The first transparent supporter plate has a first fast axis and a first slow axis, and the second transparent supporter plate has a second fast axis and a second slow axis. A direction of the second fast axis is substantially perpendicular to a direction of the first fast axis, and a direction of the second slow axis is substantially perpendicular to a direction of the first slow axis. The touch panel of the present invention is helpful to improve display quality of the touch display panel having the touch panel. | 08-26-2010 |
