Patent ID: 8334859

Claim:
An electroluminescent (EL) display device, comprising: a. a plurality of pixels spatially arranged in a form of a matrix with a plurality of rows and a plurality of columns, each pixel comprising a first EL element operably emitting light of a first color, a second EL element operably emitting light of a second color, a third EL element operably emitting light of a third color, and a fourth EL element operably emitting light of a fourth color; b. a plurality of gate lines, each gate line coupled to the respective matrix of pixels; c. a plurality of first data lines, each first data line coupled to the first EL elements of a respective column of pixels; d. a plurality of second data lines, each second data line coupled to the second EL elements of a respective column of pixels; e. a plurality of first switches, each first switch coupled to a respective third EL element, wherein the first switches coupled to the third EL elements of a respective column of pixels are configured to be cooperatively in an ON state or an OFF state; f. a plurality of second switches, each second switch coupled to a respective fourth EL element, wherein the second switches coupled to the fourth EL elements of a respective column of pixels are configured to be cooperatively in an ON state or an OFF state; g. a plurality of switch control lines, each switch control line coupled to the first switches and the second switches corresponding to a respective column of pixels for transmitting a switching control signal to set the first switches and the second switches to be in the ON state or the OFF state, such that when the first switches are cooperatively in the ON state, the second switches are cooperatively in the OFF state, and vice versus; and h. a plurality of third data lines, each third data line coupled to the first switches and the second switches corresponding to a respective column of pixels for transmitting a data signal, such that when the first switches are cooperatively in the ON state, the data signal is provided to the third EL elements of the respective column of pixels, and when the second switches are cooperatively in the ON state, the data signal is provided to the fourth EL elements of the respective column of pixels.
