Abstract
Abstract A display device includes: a light-emitting block including a plurality of light-emitting elements for emitting N number of different basic colors; an input circuit for receiving an input data representing a first color, a second color and a third color; a converter for converting the input data into an output data representing N number of basic colors; and a controller for controlling ON/OFF states of the plurality of light-emitting elements according to the output data. N is an integer of 4 or higher.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
121 words
A display device, comprising: a light-emitting block including a plurality of light-emitting elements for emitting N number of different basic colors; an input circuit for receiving an input data representing a first color, a second color and a third color; a converter for converting the input data into an output data representing N number of basic colors; a controller for controlling ON/OFF states of the plurality of light-emitting elements according to the output data, wherein N is an integer of 4 or higher, the N number of light-emitting elements are at least four light-emitting diodes which emit light of red, blue, yellow-green and blue-green, respectively, and an arrangement of said yellow-green and said blue-green light-emitting diodes provides a pure green color.
Claim 2
Dependent Claim
121 words
A display device, comprising: a light-emitting block including a plurality of light-emitting elements for emitting N number of different basic colors; an input circuit for receiving an input data representing a first color, a second color and a third color; a converter for converting the input data into an output data representing N number of basic colors; a controller for controlling ON/OFF states of the plurality of light-emitting elements according to the output data, wherein N is an integer of 4 or higher, the N number of light-emitting elements are at least four light-emitting diodes which emit light of red, blue, yellow-green and blue-green, respectively, and an arrangement of said yellow-green and said blue-green light-emitting diodes provides a pure green color.
Claim 3
Dependent Claim
117 words
A display device according to claim 1, wherein: a color production region within a region described by N number of vertices of the light-emitting block on a chromaticity diagram has a plurality of regions defined by M number of reference colors; each of the M number of reference colors are obtained based on at least one of the N number of basic colors; and the converter includes a circuit for selecting one of the plurality of regions in accordance with the input data and a circuit for generating the output data based on at least one of the M number of reference colors corresponding to a selected region within the region described by N number of vertices.
