Problems solved by technology

[0004] In order to solve the problem in the prior art that it is difficult to simultaneously balance the TV start-up time and system standby power consumption, the present invention provides a new type of quick start circuit for reducing TV standby power consumption, by adding a small CPU to the system The chip manages the power supply during the transition process of the main CPU standby and normal power-on states, and assists the main CPU to control other circuit parts in the system, thereby realizing the fast start-up of the TV and effectively reducing the standby power of the TV. consumption

Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] In order to solve the problem that the existing TV system has a large power loss during standby, which leads to energy waste, the present invention proposes a small CPU chip outside the main CPU of the system to make it stand by and normal to the main CPU. Manage the power supply during the transition of the boot state, and assist the main CPU to control other modules in the system. When the TV system enters the standby state, the small CPU chip controls the power switching circuit to switch the power supply to the main CPU from the main power supply to the standby power supply, thereby effectively reducing the standby power consumption of the entire TV system. At the same time, it also achieves The purpose of quickly starting the TV.

[0017] Television system of the present invention adopts HiDTV chip as main CPU chip 1, and...

Abstract

The invention comprises: a mini CPU, a main CPU, a main power supply, a standby power supply and an external instruction inputting unit. Said CPU chip is used to receive the turn-on / stand-by instructions from the external instruction inputting unit and further to control the switch between the main power supply and the standby power supply; the power switch circuit selects the main power supply to provide power for main CPU at time of starting the system, and selects the standby power supply to provide power for the main CPU at the time of system standby; the mini CPU is also connected to other control chips in TV set for providing a resetting signals.

Description

technical field [0001] The invention belongs to the technical field of television circuits, and in particular relates to a circuit design which can simultaneously reduce the standby power consumption of the television and shorten the start-up time. Background technique [0002] At present, in the existing television system, shutdown is divided into soft shutdown and hard shutdown. The so-called soft shutdown is to use the remote control or the buttons on the TV to enter the standby state. In the standby state, the TV is in a low-power working state, and the power consumed at this time is the so-called standby power. The so-called hard shutdown refers to AC shutdown. When the AC is turned off, the AC power supply is completely cut off. At this time, the power consumed by the machine is zero. Different movement designs have different power consumption during standby. Since the machine is still in the state of energy consumption in the standby state, the energy consumed in th...
