Abstract
Systems and methods for controlling a display apparatus are provided. In one example, an apparatus comprises a display comprising a plurality of light emitting diodes (LED), a display control circuit configured to generate display control signals, and a test module configured to generate test control signals. In a test operation mode, at least one LED of the plurality of LEDs is configured to be controlled by the test control signals from the test module to conduct at least one test output current. The test module can determine electrical characteristics of the at least one LED based on the at least one test output current. The display control circuit can adjust the display control signals based on the electrical characteristics of the at least one LED.
