Patent ID: 8913212

Claim:
A display device comprising: a plurality of display circuits arranged in M rows (M is a natural number of 2 or more) and N columns (N is a natural number), wherein the M rows include a first group of consecutive rows of the M rows, and a second group of consecutive rows of the M rows, and wherein the first group does not overlap with the second group; and a light unit overlapping with the plurality of display circuits, the light unit comprising: a plurality of light-emitting diode groups arranged in X rows (X is a natural number of 2 or more), wherein the plurality of light-emitting diode groups arranged in one of the X rows overlaps with one row of the first group of the plurality of display circuits, the plurality of light-emitting diode groups arranged in another one of the X rows overlaps with one row of the second group of the plurality of display circuits, and each of the light-emitting diode groups includes a light-emitting diode emitting red light, a light-emitting diode emitting green light, and a light-emitting diode emitting blue light; and a light guide plate formed between the plurality of display circuits and the plurality of light-emitting diode groups and in contact with the plurality of light-emitting diode groups, the light guide plate comprising X light guide members arranged in a column direction of the light-emitting diode groups so that each member corresponds to one of the rows of light-emitting diodes, the display device being configured so that the one row of the first group of the plurality of display circuits is in a writing state to be input with first display data signals corresponding to a first color or combination of colors at the same time as the one row of the second group of the plurality of display circuits is in the writing state to be input with second display data signals corresponding to a second color or combination of colors different from the first color or combination of colors, and during the writing state, the light-emitting diodes arranged in the one row of the X rows and the light-emitting diodes arranged in the another row of the X rows are in an off state, wherein each of the X light guide members overlaps a corresponding one of the X rows of light-emitting diodes, wherein side surfaces of the X light guide members have light-reflective properties, and wherein top and bottom surfaces of the X light guide members have light-transmitting properties.
