    摘要： A driving method is provided which improves the duty ratio, which presents high image quality by securing a sufficient length of sustain (lighting) period when gray scales are increased in number, and which prolongs the lifetime of a light emitting element. One frame period has m (m is a natural number equal to or larger than 2) different sub-frame periods SF1, SF2, . . . , and SFm. The m different sub-frame periods SF1, SF2, . . . , and SFm each have an address period and a sustain period. Analog data signals are inputted to their respective light emitting elements in the address period. In the sustain period, the light emitting elements emit light in response to the analog data signals at n (n is a natural number equal to or larger than 2) levels of luminance for gray scale display.

    摘要： A display device capable of displaying on both screens and switching between vertical and horizontal display, and a driving method thereof. Each pixel comprises a first region including a first light emitting element, and a second region including a second light emitting element. The first region has a bottom emission structure whereas the second region has a top emission structure. The display device comprises a source signal line driver circuit for driving the pixel, a first gate signal line driver circuit having a scan direction perpendicular to that of the source signal line driver circuit, and a second gate signal line driver circuit having a scan direction perpendicular to that of the first gate signal line driver circuit. In a normal display, the first gate signal line driver circuit performs perpendicular scanning, and when switching between vertical and horizontal display, the second gate signal line driver circuit performs perpendicular scanning.
