Abstract

A light-emitting diode (LED) strip (10) for a double-sided display screen (200) comprises a circuit substrate (11), two groups of LED lamps (12), and a protective piece (13). The two groups of LED lamps (12) are disposed on the circuit substrate (11). The protective piece (13) is disposed on the circuit substrate (11), and is used to protect the two groups of LED lamps (12) from being struck by a light-guide plate (40) during assembly. The LED strip (10) for the double-sided display screen (200) of the present invention can reduce the temperature at a light-entering part of a quantum dot (QD) fluorescent film, thereby effectively mitigating the phenomenon of blue banding.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a double-sided display screen and an LED light bar thereof. Background technique [0002] Double-sided display refers to a new type of display device with two display screens, which is more and more widely used in various service counters and windows for its upright appearance and excellent performance, such as communication industry, government window, financial It is used in business halls of window industries such as industry and transportation industry. [0003] see figure 1 , figure 1 It is a structural schematic diagram of a double-sided display screen in the prior art. [0004] Such as figure 1 As shown, the current double-sided display screen 100 is only a simple combination of two liquid crystal modules, which saves a metal back plate 60 compared with two independent liquid crystal modules, and the other parts are two LED light bars 10 and two liquid c...
