摘要： An image display device which has a stable luminous brightness among pixels. An on/off control switch 15 for stopping the driving operation of a light emitting element 13 is provided in a pixel 1. A change in the luminous brightness caused by a variation in the characteristic of the light emitting element 13 is suppressed by feeding a result measured by a current measuring circuit provided in one end of a power line 4 back to a drive signal for the light emitting element 13.

摘要： An image display device includes a black spot defect position determination circuit which determines a position of a black-spot defective pixel of a self-luminous display panel. A detection-use current source in the black spot defect position determination circuit is connected to pixels during a period separate from a display period of data signals thus determining a black spot defect. The position of the black spot defect is stored in a storing circuit and is transmitted to a display and detection control circuit. The display and detection control circuit corrects the data signals to the pixels around the defective pixel based on a black spot defect position, and drives a data line drive circuit based on the corrected data signals thus visually correcting the black spot defect.

摘要： The voltage-current property of the specific pixel is measured to store the data on a single line in a line memory. The property data of adjacent pixels are compared. A failure determination unit detects whether or not the pixel to be compared is faulty. If it is determined as being faulty, the faulty pixel is removed from the pixel group to be compared. The burn-in determination unit performs the comparison using normal pixels only to provide the correct burn-in data. The calculation unit reflects the burn-in data in the image data from the host.

摘要： There is provided a method for fabricating an image display device having an active matrix substrate including high-performance transistor circuits operating with high mobility as drive circuits for driving pixel portions which are arranged as a matrix. The portion of a polysilicon film formed in a drive circuit region DAR1 provided on the periphery of the pixel region PAR of the active matrix substrate SUB1 composing the image display device is irradiated and scanned with a pulse modulated laser beam or a pseudo CW laser beam to be reformed into a quasi-strip-like-crystal silicon film having a crystal boundary continuous in the scanning direction so that discrete reformed regions each composed of the quasi-strip-like-crystal silicon film are formed. In virtual tiles TL composed of the discrete reformed regions, drive circuits having active elements such as thin-film transistors or the like are formed such that the channel directions thereof coincide with the direction of crystal growth in the quasi-strip-like-crystal silicon film.
