The light-emitting device of a portable communication device with a projection Dlp

The invention DLP (Digital Light Processing) relates to a light emitting device of an electronic apparatus comprising a DLP projector and a display unit configured to reuse the light in the display portion backlight light generated when the projector is in operation, the electron having a DLP projector and a display unit for this purpose in the light emitting device of the machine, having a micro-mirror and the adjacent position of the flat area of ​​the projection light of the DLP projector, a flat area provided in front of the micro-mirror when the intermediate driving process in the reset of the micro-mirror is characterized in that it comprises an optical fiber to enable the optical simulation is the condenser mirror to be projected to the said flat region, the light collected by the light collecting mirror to the backlight light the display portion by passing as part the display, whereby the electron use less battery power of the device And extend between, thereby can enhance the use of electronic equipment, available DLP projector and a display unit at the same time, whereby the electronic device menu and user interface (User Interface) benefits that can improve the convenience of the switch there is. DLP projector, a display unit, the flat area, the condensing mirror, an optical fiber.
