Pixel circuits for light emitting elements

A light emitting device, comprising:

• a light emitting element;
• and
• a driving circuit for driving the light emitting element, the driving circuit comprising:
• a first type transistor receiving a data signal and comprising a first gate terminal, a first source terminal, and a first drain terminal;
• a second type transistor comprising a second gate terminal receiving a first bias signal from a first bias source, a second source terminal coupled to the first drain terminal, and a second drain terminal coupled to the light emitting element;
• a first capacitor disposed between the first gate terminal and a second bias source;
• a driving sub-circuit coupled to the first gate terminal and the first source terminal to provide the data signal and a third bias signal by a third bias source;
• a data-writing sub-circuit coupled to the driving sub-circuit to provide the data signal to the driving sub-circuit;
• and
• a second capacitor disposed between the driving sub-circuit and the data-writing sub-circuit.

A method for driving a light emitting element by a pixel circuit, wherein the pixel circuit comprises a first transistor, a second transistor disposed between the first transistor and the light emitting element, a first capacitor disposed between a first gate terminal of the first transistor and a second gate terminal of the second transistor, and a second capacitor disposed between the first transistor and a data signal source, the method comprising:

• during an initialization period, initializing a first end of the first capacitor to a first initialization bias and initializing a first end of the second capacitor to a second initialization bias;
• during a compensation period, compensating the first end of the first capacitor to a compensation bias;
• during a data writing period, providing a data signal to the first end of the second capacitor;
• and
• during an emitting period, driving the light emitting element to emit based on the data signal.
