Embodiment Construction

[0012] Below in conjunction with accompanying drawing and embodiment, describe the present invention in detail.

[0013] see figure 1 As shown, a wide viewing angle SMT liquid crystal display module with a Chinese character library includes a 3.5-inch LCD display screen, and the LCD display screen is connected to the SMT IC chip arranged on the PCB board through metal pins, and the inside of the SMT IC chip is Integrates LCD controller, LCD driver, DC / DC power boost circuit and LED brightness controller. There is also an FFC connector on the PCB board. The SMT IC chip is connected to the external control chip MCU through the FFC connector. The LCD display screen There is also an LED backlight underneath. LCD display, LED backlight, and PCB are assembled together from top to bottom to form a liquid crystal display module. The LED backlight adopts 4 bright wicks with side light emission, and the brightness is guaranteed to be 400cd / m 2 .

[0014] The LCD display adopts VA (V...

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 [0001] The invention relates to an LCD liquid crystal display module, in particular to an SMT liquid crystal display module with a wide viewing angle. Background technique [0002] As the main display device, LCD screens are widely used in many fields such as national defense, industry, household, public facilities, etc. The requirements for industrial control instrument displays are relatively high: they must be small in size, wide in operating temperature range, low in power consumption, and wide in viewing angle. Various numbers and characters. In the traditional instrument liquid crystal display, two control IC chips are required to control the LCD screen and the LED backlight, which results in a large volume of the instrument and complicated processing technology, especially the high power consumption current, which cannot meet the low power consumption requirements. Contents of the invention [0003] The purpose of the present invention is to provide...
