Konka rear projection color TV power circuit

MOS power IC full range

As shown in the figure, the power supply circuit diagram of the rear projection color TV. The rear projection is the TV behind the projection. It is a TV visualization system that combines the screen and the projection system by means of projection and reflection. In the projection display device, the projection display is divided into orthographic projections according to its projection mode (Front Projection) and back projection. The most direct application of orthographic projection is the projector, which refers to the projection of light onto the front of the screen. The principle of rear projection is simply to install the projector on the bottom of the fuselage, the signal After reflection, it is projected onto the translucent screen back. The rear projection TV is the product of this principle. According to the type of projector used internally, it can be mainly divided into LCD (liquid crystal) and DLP (digital optical path processor). Because of the integration of the projector and the screen, the rear projection TV user does not need to optically adjust the system, making it more convenient to use than the front projector.
