Projection device and control method thereof

Abstract

A projection device comprises a light source module, a light source driving circuit and a control circuit. The light source module comprises at least one light source. The light source driving circuit is coupled to the light source module. The light source driving circuit is used for controlling at least one light source of the light source module to be turned on according to the enable signal. The control circuit is coupled to the light source driving circuit. The control circuit is used for providing an enable signal to the light source driving circuit. The control circuit is used for controlling the number of times of generating the enable signal in a frame period according to the frame rate of the first image signal. In a frame period, the product of the number of times that at least one light source of the light source module receives the enable signal and the frame rate of the first image signal is greater than or equal to a reference value. The invention further provides a control method of the projection device. The projection device and the control method thereof provided by the invention can have better image quality.
