Abstract
A self-scanning, light-emitting device comprises an array of cells or blocks each having a self-scanning transfer element and a light-emitting element. Turn-on state of the transfer element is transferred to the subsequent transfer element in synchronism with clock pulses. Each light-emitting element is connected to the corresponding transfer element so as to emit light upon supplying current under an ON state of the transfer element. The light-emitting array generates a light image in accordance with a light emission current.
Claims20
A light-emitting device comprising:
- a plurality of light-emitting cells having a common substrate electrode, each having a common gate and each aligned along a row direction, said light-emitting cell including;
- a transfer element having a current electrode and said common gate;
- coupling means in conjunction with said common gate and connected between said common gates of one cell and the next;
- a light-emitting element having said common gate and another current electrode;
- at least two transfer clock lines each connected to said current electrode of said transfer elements in every at least second fashion to provide a self-scanning function therefor;
- a signal line connected to said another current electrode of said light-emitting element for receiving a light emission control current for light emission thereof;
- a bias line;
- a plurality of pull-up means each connected between said common gate and said bias line.
A light-emitting device comprising:
- a plurality of light-emitting blocks each aligned along a row direction, said light-emitting block including;
- a transfer element having a current electrode, a gate and a common electrode extending along said row direction;
- coupling means in conjunction with said gate and connected between said gates of one transfer element and the next;
- a light-emitting element isolated from said transfer element and having another gate operatively connected to said gate of said transfer element and another current electrode;
- at least two transfer clock lines each connected to said current electrode of said transfer element in every at least second fashion to provide a self-scanning function therefor;
- a signal line connected to said another current electrode of said light-emitting element for receiving a light emission current for light emission thereof;
- a bias line;
- and
- a plurality of pull-up means each connected between said gate of said transfer element and said bias line.
