Light emitting device control circuit and control method thereof

Abstract

The present invention discloses a light emitting device control circuit and a control method thereof, for controlling a light emitting device array display. The present invention controls not only the conduction timing and duration of one or more selected light emitting devices in the light emitting device array display, but also controls the current flowing through the selected light emitting devices by a variable current source, such that in one frame of a given length, the resolution of the brightness of the light emitting devices is increased.

Description

technical field [0001] The present invention relates to a light-emitting element control circuit and a control method, in particular to a light-emitting element control circuit and a control method capable of accelerating the refresh rate. Background technique [0002] Figure 1A A schematic diagram of a light emitting element control circuit 110 in the prior art is shown, wherein the light emitting element control circuit 110 is used to control the image and brightness of the light emitting element array display circuit 10 . like Figure 1A As shown, the power supply circuit 120 supplies power to the light-emitting element array display circuit 10, and the light-emitting element control circuit 110 determines which light-emitting elements in the light-emitting element array display circuit 10 should be turned on and illuminated, and what kind of light-emitting elements should be illuminated. brightness. To simplify the drawing, only the light-emitting element control circu...
