Abstract

The invention discloses an OLED driving power supply and an OLED TV. The OLED driving power supply includes: a main power supply, an on-screen power supply and a main board, wherein the on-screen power supply and the main board are electrically connected to the main power supply, and the main board is used for outputting switching signals and controlling the OLED signal, the on-screen power supply is used to light up or extinguish the OLED screen according to the OLED control signal; the main power supply includes: a power supply circuit and a standby circuit; wherein, the first end of the standby circuit is electrically connected to the power supply circuit, and the second end of the standby circuit is connected to the main board Electrically connected, the third end of the standby circuit is electrically connected to the power supply on the screen; the power supply circuit outputs a standby signal or a working signal to the main board according to the switch signal. The invention receives the switch signal through the standby circuit, and then outputs the standby signal or the working signal to the main board to control the main board to be in standby or work. According to the switching signal, the working state of the main board can be accurately controlled to ensure the stability of the power supply output. The circuit is simple and reduces the Product Cost.

Description

technical field [0001] The invention relates to the technical field of TV power supplies, in particular to an OLED driving power supply and an OLED TV. Background technique [0002] OLED (organic light emitting diode) does not need backlight, color filter and liquid crystal, and can emit light by itself. It is superior to traditional LCD and LED in terms of image quality, response speed, thickness and viewing angle, and is widely used. application. [0003] At present, the power supply of OLED TV needs to meet the requirements of power output stability, the circuit is complicated and the cost is high. [0004] Thereby prior art still needs to improve and improve. Contents of the invention [0005] In view of the deficiencies of the above-mentioned prior art, the purpose of the present invention is to provide an OLED drive power supply and an OLED TV. The standby circuit outputs a standby signal or a working signal according to the switch signal, and the main board is con...
