  • Luminescence brightness compensation structure of field-emission display
    Patent number: 7242139
    Abstract: A luminescent brightness compensation of sub-pixels of tri-electrode based field-emission display. The cathode conductive layers corresponding to sub-pixels constituting a pixel are arranged at various levels according to the respective luminescent efficiencies thereof. Thereby, the color with lower or higher luminescent efficiency obtains a stronger or weaker electric field between anode and cathode, respectively. Therefore, the different luminescent efficiency of three sub-pixels with primary color is compensated.

  • Radio interference indicator
    Publication number: 20070123169
    Abstract: The present invention provides a radio interference indicator comprising a controller for processing an instruction and a radio signal receiver coupled to the controller to receive or detect a radio signal. An indicating element is coupled to the controller to indicate the level of the radio signal to allow the user knows the quality of the background the radio signal.

  • Luminescence brightness compensation structure of field-emission display
    Publication number: 20050231099
    Abstract: A luminescent brightness compensator of a field-emission display has three primary colors cathode conductive layers arranged at various levels according to the respective luminescent efficiencies thereof. Thereby, the color (blue) has the lowest luminescent efficiency gains a strong electric field to the anode electrode, such that more electrons are drained to generate this color light. Therefore, the different luminescent efficiency of three primary colors is compensated, and a better color image can be obtained.
