Toshiba Corp. showed a player of the motor vehicles of HD DVD and a liquid crystal display of panel of contact to the \ “with the exposure of the motor vehicles 2007 of technology. \” the company codéveloppe currently the player of the motor vehicles of HD DVD with Alpine Electronics, Inc. with an aim of releasing a product in 2008 tax. Toshiba showed the player by the video running really with the exposure. While waiting, the liquid crystal display of panel of contact was a prototype presented by technology Co., Ltd (TMD) of posting of Toshiba Matsushita. TMD integrated an optical probe with a transistor formed on each Pixel on the panel. This technology makes it possible the panel to detect the shade of a finger when the panel is touched and work like panel of contact during the day.

The night, the panel can feel contacts of finger by using the back-light, which reflects when a finger touches the panel. Compared with the existing panels of contact, which are coated with a transparent film, prototyped uses of display panel to crystals liquid any film thus coating the brightness of screen is not shortened by lower transparency and the report/ratio of contrast is not due affected to the reflexion of the external light, whereas the costs can also be due tiny room to the reduction in the component count, praised TMD. TMD envisages to advance the marketing of the display panel to liquid crystals, but there are challenges coming from the two methods various employees to identify contacts of finger during day and night. Two applications different of software are required for the night and the day, just as a method to determine if it is night or day and commutation between feeling methods. TMD indicated that it will address these challenges by presenting a new method which makes it possible the panel to identify contacts of finger if it is night or day by using the rays of infra-red which radiate back-light, between other measurements.
