Display apparatus, display method and method of manufacturing a display apparatus
View Patent ↗To precisely reduce fluctuations in brightness of respective light emitters when displaying an image by having a plurality of light emitters emit light, and thereby improve image quality. A display apparatus can be made of an arrangement of a plurality of pixels respectively composed of a predetermined driving circuit and a light emitter that emits light when driven by the driving circuit. Each pixel can include a correction circuit that detects an amount of light for the light emitter using a light receiver made of the same type of material as the light emitter and implements feedback control over the driving circuit based on a detection result.
1. A display apparatus composed of an arrangement of a plurality of pixels respectively composed of a predetermined driving circuit and a light emitter that emits light when driven by the driving circuit,
each pixel including a correction circuit that detects an amount of light for the light emitter using a light receiver made of a same type of material as the light emitter and that implements feedback control over the driving circuit based on a detection result, the correction circuit being composed of a resistor and a phototransistor whose resistance changes in accordance with an amount of received light, and being a series circuit that is coupled in parallel to a data voltage holding capacitor that is a component in the driving circuit.
2. A display apparatus according to claim 1 , the correction circuit detecting an amount of external light and implementing feedback control of the driving circuit based on a detection result.
3. A display apparatus according to claim 1 , the light receiver being formed of an organic EL display material.
4. A display apparatus according to claim 1 , the light emitter being formed of an organic EL display material.
5. A display apparatus according to claim 1 , the organic EL display apparatus being composed of a plurality of the pixels arranged in two dimensions.
6. A display apparatus according to claim 1 that displays in color.
