Abstract

The utility model relates to the field of displays, in particular to the field of liquid crystal displays. The four-in-one liquid crystal display module comprises liquid crystal screens, a backlight source and a control circuit, wherein the liquid crystal screens are arranged on a PCB circuit board. Further, four liquid crystal screens are sequentially horizontally distributed on the PCB circuit board, the control circuit comprises three LCD control drive modules and two LCD drive modules, and the three LCD control drive modules and the two LCD drive modules are connected by means of bus connection. By adopting the technical scheme, the four-in-one liquid crystal display module has the advantages of simplifying control lines, narrowing the overall volume of the display module and leading instruments to miniaturization development.

Description

A kind of LCD MODULE of four unifications

Technical field

The utility model relates to field of display, relates in particular to field of liquid crystal.

Background technology

It is thin that LCDs has a fuselage, saves the space: compare with relatively heavier CRT monitor, as long as LCD is the former 1/3rd space; Power saving does not produce high temperature: it belongs to the low power consumption product, can accomplish not generate heat fully (main power consumption and heating part are present in backlight lamp tube or LED), and CRT monitor, because of imaging technique unavoidably produces high temperature; Radiationless, benefit is healthy: LCD is radiationless fully, and this is for Gospel of the people Lai Shuoshi that works before computer all day; The soft eye of not hindering of picture: be different from the CRT technology, LCD picture can not glimmer, and can reduce the injury of display to eyes, and eyes are not easy fatigue.The display intellectualized operation, digital control, digital demonstration is the necessary condition of following display.Along with the arriving of digital Age, digital technology will replace analogue technique comprehensively, and the little advantage of these volumes of liquid crystal is easier to integrated advantage and causes LCD will replace present simulation CRT monitor soon comprehensively.In many instrument display systems in the past, often need complicated line to connect and expend many spaces and furnish a plurality of CRT monitor and carry out muti-display functionality.In addition, present liquid crystal display systems is that a table is joined a LCD MODULE mostly, causes the on the high side of the specification of instrument and module.

The utility model content

At the problems referred to above, need be made in a plurality of display parts on the LCD module, select mode to control each display part respectively by MCU with sheet, simplified operation circuit, dwindled the overall volume of display module, instrument is developed to miniaturization.

Concrete technical scheme of the present utility model is:

The LCD MODULE of four unifications of the present utility model comprises the liquid crystal display, backlight and the control circuit that are arranged on the PCB circuit board.Further, described liquid crystal display is 4, and cross direction profiles is arranged on the PCB circuit board successively, and described control circuit comprises 3 LCD control and driving module and 2 LCD driver modules, and couples together with the bus ways of connecting.

Further, the both sides of described PCB circuit board are equipped with the wiring through hole that plural number is vertically arranged, and the output port of described wiring through hole and control circuit electrically connects.

Further, described backlight is the white light backlight, and drives by backlight module, and the port of described backlight module is connected on the described wiring through hole.

The utility model adopts as above technical scheme, has to have simplified operation circuit, has dwindled the overall volume of display module, makes the advantage of instrument to the miniaturization development.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an electrical block diagram of the present utility model.

Embodiment

Now with embodiment the utility model is further specified in conjunction with the accompanying drawings.

Consult shown in Figure 1, of the present utility model four the unification LCD MODULE, comprise the liquid crystal display, backlight and the control circuit that are arranged on the PCB circuit board 1.Described liquid crystal display is 4, is respectively a LCD module 11, the 2nd LCD module 12, the 3rd LCD module 13, the 4th LCD module 14, and cross direction profiles is arranged on the PCB circuit board 1 successively.LCD module 11 among the embodiment of the present utility model is LCD modules of 8*1, and the 2nd LCD module 12 also is the LCD module of 8*1, and the 3rd LCD module 13 is LCD modules of 16*3, and the 4th LCD module 14 is LCD modules of 16*3.Described 4 LCD modules each other be spaced apart 5mm, be arranged in together closely.

The both sides of described PCB circuit board 1 are equipped with the wiring through hole 10 that plural number is vertically arranged, and the output port of the control circuit on described wiring through hole 10 and the PCB circuit board 1 electrically connects.Insert in the instrument system by wiring through hole 10 again.

Consult shown in Figure 2ly, described control circuit comprises 3 LCD control and driving module and 2 LCD driver modules, and couples together with the bus ways of connecting.Wherein, the COM port of LCD control and driving module 21 and SEC port are connected to a LCD module 11, the 2nd LCD module 12 is carried out drive controlling; LCD control and driving module 22 and LCD driver module 23 be drive controlling the 3rd LCD module 13 together, and the SEC port of the COM port of LCD control and driving module 22 and SEC port, LCD driver module 23 inserts LCD panel controlling and driving; LCD control and driving module 24 and LCD driver module 25 be drive controlling the 4th LCD module 14 together.Control circuit connects altogether/the CS1 port ,/the CS2 port ,/CS3 port, VO port, RS port, SI port, SCL port.Adopt 4 line SPI interfaces, each display part selects CS control to show by sheet, selects mode to control each display part respectively by MCU with sheet.Described backlight is the white light backlight, and drives by backlight module 3, and the LED+ port of described backlight module 3, vdd terminal mouth, LED-port, VSS port are connected on the described wiring through hole 10.

Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in the spirit and scope of the present utility model that do not break away from appended claims and limited; can make various variations to the utility model in the form and details, be protection domain of the present utility model.
