Abstract
A method for controlling spacer (108) visibility in a field emission display (100) includes the steps of modifying pixel data for transmission to a plurality of pixels (110) in a first region (112) adjacent to a spacer (108) to render the spacer (108) invisible to a viewer of the field emission display (100). A field emission display (100) with a spacer visibility correction circuit (104) that modifies pixel data for transmission to a plurality of pixels (110) in a first region (112) adjacent to a spacer (108).

A method for controlling spacer visibility in a field emission display (100) comprising the steps of:
- providing a display (106) having a plurality of pixels (110) in a first region (112) and a plurality of pixels (110) in a second region (114), wherein the first region (112) is adjacent to a spacer (108) and the second region (114) is not adjacent to the spacer (108);
- providing a memory (152) having memory data (153);
- receiving a video signal (102) having pixel data indicating an intensity level of light to be generated by each of the plurality of pixels (110) in the first and second regions (112, 114) of the display (106);
- comparing the pixel data to the memory data (153) to determine the pixel data to be transmitted to the plurality of pixels (110) in the first and second regions (112, 114) of the display (106), wherein the pixel data to be transmitted to the second region (114) defines a second region pixel data (180);
- transmitting the second region pixel data (180) to the second region (114) of the display (106);
- and
- modifying the pixel data for transmission to the first region (112) of the display (106) to correspond to the intensity level of light generated by the plurality of pixels (110) in the first region (112) in order to render the spacer (108) invisible to a viewer of the field emission display (100), wherein the pixel data to be transmitted to the first region defines a first region pixel data (178).
A field emission display (100) comprising:
- a plurality of pixels (110) in a first region (112) and a plurality of pixels (110) in a second region (114), wherein the first region (112) is adjacent to a spacer (108) and the second region (114) is not adjacent to the spacer (108);
- a video signal (102) having pixel data indicating an intensity level of light to be generated by each of the plurality of pixels (110) in the first and second regions (112, 114) of the field emission display (100);
- and
- a spacer visibility correction circuit (104) having an input (101) and an output (103), wherein the input (101) is coupled for receiving the video signal (102) having pixel data and the output (103) is coupled for transmitting a first region pixel data (178) to the plurality of pixels (110) in the first region (112) and a second region pixel data (180) to the plurality of pixels (110) in the second region (114) of the field emission display (100) in order to render the spacer (108) invisible to a viewer of the field emission display (100).
