Patent ID: 8049685

Claim:
A passive-matrix, thin-film electro-luminescent display system, comprising: a) a display including: i) a substrate; ii) a first electrode layer patterned to form lines along a first dimension of the substrate; iii) one or more thin-film electro-luminescent layers, formed on the first electrode layer; iv) a second electrode layer formed on the one or more thin-film electro-luminescent layer(s), wherein the second electrode layer is patterned to form lines along a second dimension of the substrate different from the first dimension; v) wherein the intersection of the lines of the first and second electrode layers define individual light-emitting elements comprising an electro-luminescent unit; and b) one or more display drivers that i) receives an input image signal for addressing the light-emitting elements of the display; ii) decomposes the signal into a low-resolution component signal and a high-resolution component signal, each of which consists of different addressable locations during a single frame cycle, wherein the low-resolution component signal contains one half or less of the number of the addressable locations as the high-resolution component signal, and the low-resolution component signal and the high-resolution component signal are driven alternately; and iii) provides a drive signal for driving the display wherein the low-resolution component signal and the high-resolution component signal are independently provided to the display to form a combined image.
