摘要： An multi-touch detection system (100) separately determines each of the coordinates of multiple touches and is able to correctly pair the coordinates, the touch panel includes multiple (e.g., two or four) separate sections (104, 106, 404, 406, 504, 506, 508, 510) to detect touches in different areas. The system (100) is able to operate at high refresh rates allowing speed sensitive applications to be supported.

摘要： Disclosed is reflective morphable display with multi-layered depth viewing, low power consumption and few components and a method of activating various features thereof. The disclosed display includes a bi-stable reflective cholesteric liquid display crystal (ChLCD) layered in combination with a display device such as an LCD and a quarter lambda (λ/4) retardation film layer. Linearly polarized light emerging from the front surface of a display device is circularly polarized by the λ/4 layer before entering the ChLCD layer. In its reflective state, the ChLCD layer receiving a portion of the ambient light having the same handedness of the ChLCD is reflected in a mirror-like manner. Also in its reflective state, when it receives light that is circularly polarized by the λ/4 retardation film layer, the ChLCD layer acts as a shutter. A display device with depth viewing is provided as the ChLCD layer pixelated so it is configured to display font and/or other indicia.
摘要翻译： 公开了具有多层深度观察，低功耗和少量组件的反射变形显示以及激活其各种特征的方法。 所公开的显示器包括与诸如LCD和四分之一λ（λ/ 4）延迟膜层的显示装置组合的双稳态反射胆甾型液晶显示晶体（ChLCD）。 在进入ChLCD层之前，从显示装置的前表面出射的线偏振光被λ/ 4层圆偏振。 在其反射状态下，接收具有ChLCD相同手性的环境光的一部分的ChLCD层以镜像的方式反映。 同样在其反射状态下，当它接收到被λ/ 4延迟膜层圆偏振的光时，ChLCD层用作快门。 具有深度观看的显示设备被提供为ChLCD层像素化，因此被配置为显示字体和/或其他标记。

摘要： A two-way trans-reflective display pixel (100) having two viewable sides (102, 104) is disclosed. The two-way trans-reflective display pixel has a first transparent layer (106), a second transparent layer (108), and light modulating medium (110) sandwiched between them. Both the first and second transparent layers (106, 108) have light reflectors (132, 136) and light absorbers (130, 134), which allow light entering from either viewable sides (102, 104) to partially reflected, partially absorbed, and partially transmitted, allowing an image to be viewable from both viewable sides (102, 104). A two-way trans-reflective display (402) comprising a plurality of two-way trans-reflective display pixels (100) and a transparent light source (412) is also disclosed. The transparent light source (412) provides color light, and enables an image from the two-way trans-reflective display (402) to be viewable in color from both first and second viewable sizes (418, 602).
