Abstract
The invention relates to a wide-angle SMT (surface mounted technology) liquid crystal display module, which comprises an LCD (liquid crystal display) display screen, an LED (light-emitting diode) backlight source, a PCB (printed circuit board), an SMT IC (integrated circuit) chip and an FFC (flexible flat cable) connector. The LCD display screen is connected with the PCB through metal pins, the LED backlight source is arranged under the LCD display screen, the SMT IC chip and the FFC connector are arranged on the PCB, the SMT IC chip is connected with an external control chip MCU (micro control unit) through the FFC connector, and the LCD display screen adopts a VA (vertical alignment) liquid crystal display technology for wide-angle display. The invention has the advantages that the driving of the LCD display screen and the control of the brightness of the LED backlight source can be achieved only through one SMT IC chip, and the wide-angle SMT liquid crystal display module has a small size, can be installed conveniently and has ultra-low consumption.
Description
Technical field
The present invention relates to a kind of LCD LCD MODULE, relate in particular to a kind of SMT LCD MODULE of wide visual angle.
Background technology
The LCD screen is as main display device; Be widely used in numerous areas such as national defence, industry, family expenses, communal facility, industrial control instrument display requires than higher: must be that volume is little, the operating temperature range of broad, low-power consumption, wide visual angle show various numerals and character.Traditional instrument LCD, control LCD screen needs two control IC chips with the LED-backlit source, and this has just caused the instrument volume big, and processing technology is complicated, and especially static current of lcd is high, can not satisfy the low-power consumption requirement.
Summary of the invention
The SMT LCD MODULE that the purpose of this invention is to provide a kind of wide visual angle adopts a SMT IC chip can realize driving LCD display and control LED-backlit source brightness, and volume is little, be convenient to super low-power consumption is installed.
For realizing above-mentioned purpose, the present invention realizes through following technical scheme:
A kind of SMT LCD MODULE of wide visual angle comprises LCD display, LED-backlit source, pcb board, SMT IC chip, FFC connector; LCD display is connected with pcb board through metal pin; The LED-backlit source is arranged on the LCD display below, and SMT IC chip and FFC connector are arranged on the pcb board, and SMT IC chip is connected with external control chip MCU through the FFC connector; Said LCD display adopts the vertical orientated lcd technology of VA, realizes that wide visual angle shows.
The metal pin material of said LCD display is that copper plating nickel on surface or tin are formed.
Luminous 4 the SMT wicks of sidepiece are adopted in said LED-backlit source, and brightness guarantees at 400cd/m
2
Compared with prior art, the invention has the beneficial effects as follows:
The present invention adopts a SMT IC to realize driving LCD screen and the source brightness of control LED-backlit, compact conformation, and volume is little, super low-power consumption; Use the LED-backlit source working at night, use wide temperature liquid crystal under subzero 30 degree, to work; Use VA technology, make LCD realize that wide visual angle shows.

Embodiment
Below in conjunction with accompanying drawing and embodiment, be described in detail the present invention.
Referring to shown in Figure 1; A kind of wide visual angle SMT LCD MODULE with Chinese character base; Comprise 3.5 inches LCD display; LCD display is connected with SMT IC chip on being arranged on pcb board through metal pin, and described SMT IC chip internal integrated LCD controller, lcd driver, DC/DC power supply booster circuit and LED brightness controller also are provided with the FFC connector on the pcb board; SMT IC chip is connected with external control chip MCU through the FFC connector, and said LCD display below also is provided with the LED-backlit source.LCD display, LED-backlit source, pcb board are assembled together from top to bottom successively, constitute LCD MODULE.Luminous 4 the high bright wicks of sidepiece are adopted in said LED-backlit source, and brightness guarantees at 400cd/m
2
Said LCD display adopts VA (Vertical Alignment) technology, realizes that wide visual angle shows; Said metal pin material is copper, plating nickel on surface and tin.
External control chip MCU to SMT IC chip input data, realizes control and driving to LCD display and LED-backlit source by SMT IC chip through 3 line serial line interfaces, can be implemented in the brightness that shows required content and adjustment LED-backlit source on the LCD screen thus.
The present invention adopts a SMT IC chip can realize driving LCD display and control LED-backlit source brightness, adopts SMT surface mounting technology (Surface Mounted Technology), and volume is little, be convenient to super low-power consumption is installed.
