A display system includes a host apparatus having a video interface circuit and a display apparatus operated by feed of a video image and power from the host apparatus, and also has a communication function for receiving and transmitting data between the host apparatus and the display apparatus. In the display system, the display apparatus transmits power consumption data thereof stored in an EEPROM to the host apparatus and processes the power consumption data thereof which is received by the host apparatus, thus controlling power of the display system including the host apparatus and the display apparatus.

Display system and microdisplay apparatus

A table type display device, in which a high resolution display with an unremarkable connection is realized at the time of large screen display by using a screen with a composition having few bending is described. In a table type display device comprising plural M of projectorsL,R for projecting luminous flux to form an image, plural N of reflection mirrorsL,R for bending optical paths of luminous fluxes projected from respective plural M of projectorsL,R, screenof horizontal installation type for projecting luminous fluxes for which optical path is bent, by the plurality N of reflection mirrorsL,R onto the predetermined region, respectively, the screen comprises a transparent base memberfor reducing flexure of the screen, optical sheetsubstantially for making luminous fluxes projected respectively from the plural M of projectorsL,R uniform, and a diffusing screen for imaging the image.

Table type display device

A table type display device capable of selecting the best projector according to user's budget and mode is provided for with easy exchange of the projector. The table type display device comprises four projectorsLU,LL,RU, andRL for projecting luminous flux to form image, reflection mirrorsU andL for bending an optical path of luminance flux projected from each of these projectors, and a screenof horizontal installation type for projecting luminous flux with its optical path being bent by reflection mirrorsU andL, onto predetermined regions respectively. The screen housing portionof the main body unitaccommodates the screen, the reflection mirrorsU andL, and the light shading platesLU,LL,RU, andRL, and the projector unit housing portionof the main body unitaccommodates projectorsLU,LL,RU, andRL housed by the projector unit
