Definitions

  • the present invention generally relates to a light emitting device display techniques, and more particularly, to a technique for driving light emitting elements that uses a feedback architecture during programming to compensate for instability and non-uniformity of the pixels .
  • OLED organic light-emitting diode
  • the present invention provides several driving circuits having a feedback control-system architecture that can be used for driving a column of the light emitting devices and are suitable for use in AMOLED displays.
  • a feedback voltage is generated by an on-pixel feedback circuit or element. This voltage is used to adjust the programming voltage of the pixel.
  • FIG. 4 is a circuit diagram of a modification of the embodiment of FIG. ' 3 A;
  • Fig. 10 is a circuit diagram of a modification of the embodiment of Fig. 9;
  • FIG. 12 is a circuit diagram of a pixel circuit, column control unit and a reference cell with implemented luminance feedback according to an embodiment of the invention
  • the anode of OLED 51 is connected to the source terminal of transistor 56.
  • the feedback resistor 32 is connected between the drain terminal of transistor 56 and ground node.
  • the voltage level of the select line during the writing mode should be high enough to guarantee that transistor 54 is in "on" state for the entire output current range.
  • the feedback line in this configuration is connected to the non-inverting input of the difference amplifier 33 to provide a negative feedback.
  • the circuit is balanced when the input cunent passing through the resistor Rl is equal to a feedback cunent generated by the photodiode 125.
  • the cunent flowing through OLED 124 via transistor 122 and resistor 42 is an input signal for next stage of the device, which is the same as the embodiment of FIG.4.
