Abstract: An organic electroluminescent display panel and a display apparatus are disclosed. At a first detection phase, aging of the light-emitting device in each sub-pixel is detected one by one. At a display phase, an initial grayscale value for a corresponding sub-pixel is compensated in accordance with the aging of the light-emitting device in each sub-pixel. Moreover, in the display panel the plurality of sub-pixels that belong to the same pixel group share a sense line, such that the number of the wirings in the display panel can be reduced and the number of the signal channels of the driving chip can thus be reduced, leading to a reduced area of the driving chip and a reduced manufacture cost.

Abstract: The present application discloses an analog-to-digital conversion (ADC) circuit. The circuit includes an integral circuit including an operational amplifier and an integral capacitor. The circuit further includes a comparator and a timer. The operational amplifier includes a positive input terminal configured to receive a first voltage, a negative input terminal coupled to a signal-collection line configured to collect an analog current signal, and an output terminal configured to output a first output signal. The comparator is configured to compare the first output signal with a second voltage to generate a second output signal to the timer. The timer is configured to start a timing operation when the operational amplifier receives the analog current signal and end the timing operation when the second output signal changes. A binary data resulted from the timing operation characterizes a digital signal corresponding to the analog current signal.
