Problems solved by technology

However, the use of electromagnetic screen technology usually requires the electromagnetic board to be installed on the LCD screen. For side-in LED backlight displays, because the light source is installed around the LCD screen, the electromagnetic board will not affect the light source when installed on the LCD screen. The effect on the LCD screen; however, for the direct type LED backlight display, because the light source is set on the front and back of the LCD screen, when the electromagnetic board is installed on the LCD screen, it will seriously affect the effect of the light source on the LCD screen

Embodiment Construction

[0029] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] Such as figure 1 As shown, the embodiment of the present invention proposes a direct-lit backlight display module, including a backlight module 100 and a liquid crystal panel 300 corresponding to each other, and a main control circuit connected to the backlight module 100 and the liquid crystal panel 300 . By setting a main control circuit connected to the backlight module 100 and the liquid crystal panel 300, the backlight module 100 and the liquid crystal panel 300 can be controlled, so as to realize liquid crystal display or other functions.

[0031] And, if Figure 2 to Figure 4 As shown, the backlight module 100 includes a backplane 110, a light-emitting structure disposed on the backplane 110, a diffusion plate 140 facing the light-emitting structure, and a light-emitting structure disposed on the liquid crystal panel 300. The electromag...

Abstract

The invention discloses a direct type backlight display module and display equipment. The module comprises a backlight module, a liquid crystal panel corresponding to the backlight module, and a master control electric circuit connected to the backlight module and the liquid crystal panel, wherein the backlight module is composed of a backboard, a luminous structure positioned on the backboard, a diffusion plate opposite to the luminous structure and an electromagnetic input module arranged between the luminous structure and the liquid crystal panel; the electromagnetic input module comprises an electromagnetic mebrane positioned between the luminous structure and the liquid crystal panel, an electromagnetic control circuit electrically connected to the electromagnetic mebrane; the light transmittance ratio of the electromagnetic mebrane is bigger than or equal to 50%, and the electromagnetic mebrane is connected to the master control electric circuit through the electromagnetic control circuit. According to the technical scheme, the input function based on electromagnetic touch control is integrated with the direct type backlight display module, so that a great display effect of the liquid crystal display is also ensured.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a direct-lit backlight display module and a display device. Background technique [0002] In traditional technology, liquid crystal display has become the mainstream display in the market due to its characteristics of low electromagnetic radiation, low power consumption, low heat generation, and thinness. LED backlight displays have also been widely used. Currently, LED backlight displays on the market are mainly divided into two types, side-lit and direct-lit, according to the way of light incident. Among them, the side-in type is to install the LED light string as the backlight module around the LCD screen, and the direct type is to install the LED light string as the backlight module on the front and back of the LCD screen. Lower cost and wider application. [0003] However, in the conventional technology, the direct-lit backlight display can only be used as a displa...
