Embodiment Construction

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0033] This application is mainly aimed at a display device with a rotatable display screen, and the structure, function and implementation of the display device will be described in detail below.

[0034] Currently, some split-type display devices have become a new form, for example: split TV. The split-type display device can separate the display screen from the main body of the display device and set it as a separate structure, that is to say, th...

Abstract

The invention provides a display device. A feedback circuit in the host unit of the display device can adjust the voltage output by the power supply circuit according to the feedback signal sent by the backlight control circuit in the display screen, so that the split type display device can realize voltage feedback adjustment. Meanwhile, the power supply circuit for supplying power to the feedback circuit adopts a self-powered mode of an electric signal output by the power supply circuit, and adjusts the electric signal to a voltage required by the work of the feedback circuit through a triode, so that the host unit can control the power supply circuit to output a stable voltage according to the feedback signal; and meanwhile, the problems of high cost and narrow adaptive voltage range when the power supply circuit supplies power to the feedback circuit by using an electric signal output by the power supply circuit are solved, and the reliability and compatibility of the circuit are improved.

Description

[0001] This application claims the priority of a Chinese patent application with application number 2020100747123 and application title "display device" filed with the China Patent Office on January 22, 2020, the entire contents of which are incorporated herein by reference. technical field [0002] The present invention relates to the field of electronic technology, in particular to a display device. Background technique [0003] With the continuous development of electronic technology, manufacturers of display devices such as TVs have proposed split-type design ideas. Taking split-type TVs as an example, split-type TVs separate the display screen from the main body of the TV as a separate According to the structural setting, some individually set display screens can also be rotated by motors. Therefore, by adopting the split structure, the display screen can be made lighter and thinner without being limited by the display device, and the space occupied by the TV can be red...
