Electric storage type LED display system and display module group structure thereof

Abstract

The invention relates to the LED display screen technology field and especially relates to an electric storage type LED display system and a display module group structure thereof. The electric storage type LED display system comprises a control unit and at least one display unit controlled by the control unit. Each display unit comprises a display module group, a first energy storage battery, a first charge protection module and a first discharge protection module, wherein the first energy storage battery, the first charge protection module and the first discharge protection module are assembled with the display module group into one body. The first charge protection module, the first discharge protection module and the display module group are controlled by the control unit. The system and the structure are provided with an energy storage component. Through dispersing a battery pack in the form of a plurality of energy storage batteries to each display unit of an LED display screen,the power supply mode of the existing LED display screen can be changed. From the aspects of energy conversion efficiency and display screen configuration cost, the power supply mode of the inventionis better than the power supply mode of using the battery pack as secondary voltage conversion. The system and the structure are easy to implement and popularize, social resource optimization utilization can be achieved and economic benefits are increased.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to a power storage LED display system and a display module structure thereof. Background technique [0002] As we all know, the LED display module is the basic unit of the LED display screen. The existing LED display modules generally use the AC→DC power supply module installed in the LED display screen to convert the mains power (ie: AC power) into DC power. For driving, usually one AC→DC power supply module can drive multiple LED display modules connected in parallel. The energy conversion efficiency of this kind of power supply driving mode is low (generally lower than 85%), and the failure rate is high, and once the mains (ie: alternating current) power failure occurs, the LED screen will not display due to power failure. [0003] In order to solve the problem that the LED screen cannot be displayed after the mains power failure, the industry has proposed a method o...

Problems solved by technology

However, the battery pack is not suitable as an energy storage application. First, the efficiency of the output current of the battery pack is very low (the overall efficiency is lower than 50%) after two conversions, which greatly causes a waste of electric energy; secondly , when facing the LED display screen of tens to hundreds of square meters, it is equivalent to facing the electric load of tens to hundreds of kilowatts, it is necessary to store and convert the battery pack, which greatly increases the LED display capacity. The configuration cost of the display screen is low, and the economic benefit is low
