Electro-optical device and method of driving the same, organic electroluminescent display device, and electronic apparatus

Abstract

To reduce the power consumption of an organic electroluminescent display device. The organic electroluminescent display device includes organic electroluminescent elements corresponding to R, G, and B colors, holding capacitance, etc., which are disposed at intersections of data lines X1 to X12 and scan lines Y1 to Y7 which are arranged in a matrix manner, a data line driving circuit 40, and a scan line driving circuit 30. The scan line driving circuit 30 includes a decoder 33. An auxiliary data line driving circuit 50 is provided in addition to the data line driving circuit 40. The auxiliary data line driving circuit 50 includes a decoder 51, and a plurality of switching elements 52. First ends of the switching elements 52 are selectively connected to only the data lines X2, X5, and X8, of the data lines X1 to X12, which correspond to the organic electroluminescent elements capable of emitting green (G). Second ends of the switching elements 52 are connected to a power supply line 53 on which a character display voltage VCHR for causing the organic electroluminescent elements to emit light is fed.

Problems solved by technology

[0013] In short, in the above-mentioned existing structure, when displaying characters such as letters or symbols, as when displaying images, it is necessary to perform work with high power consumption. In addition, the scanning lines Y1 to Ym must also be driven for areas where characters are not displayed. So it is a structure that consumes power in vain

[0014] In addition, not only when display control is performed, but also when disconnection checks and pre-charging are performed, power is consumed in vain.
