Patent ID: 8525757

Claim:
A display device comprising: horizontal scan lines disposed in parallel in the column direction of a matrix to supply a video signal; vertical scan lines disposed in parallel in the row direction of the matrix to supply a vertical scan signal; an electro-optical element disposed at each of positions where the horizontal scan lines and the vertical scan lines intersect and selectively turned on based on the video signal and the vertical scan signal; a defect information storing section that stores defect information indicating whether each of the electro-optical elements has a defect or not; a video signal generating section that generates the video signal to be supplied to the electro-optical element in each position based on an outside video signal supplied from outside and the defect information stored in the defect information storing section and; a defect information accepting section that accepts the defect information from a defect information generating section that generates the defect information provided externally, wherein the defect information obtained from the defect information generating section through the defect information accepting section is stored in the defect information storing section, wherein the defect information accepting section accepts bright dot defect information from a bright dot defect determining section provided externally for determining whether the electro-optical elements are emitting light with high brightness out of the normal range or not, wherein the video signal generating section supplies the video signal to the electro-optical elements, wherein the video signal supplied to the electro-optical element having at least one of the defect information and the bright dot defect information is set to a black level, and wherein the video signal supplied to the electro-optical element having no defect is set to a level of the outside video signal.
