LK162-12-IY-V-E is a widely used numerical LCD display module that features a wide variety of features for various applications such as Automotive, Industrial, Medical, and Military. This article introduces the application field and working principle of the LCD module.

Application Field

With its LEDs, LK162-12-IY-V-E provides dual color display capabilities. This module is typically used in applications like instrument panels and field indicators where special dual mode operation is required. The display module is also used in automotive accessories like light, audio and power equipment where quick response time and low power consumption is needed.

The module is also used in medical LCD displays for applications like patient monitoring systems and medical equipment which require a large number of characters. LK162-12-IY-V-E is also used in industrial applications such as factory machine control panels and remote display units.

Working Principle

LK162-12-IY-V-E can display up to 8 groups of 8-segment characters, a total of 64 decimal characters. It is made up of 4 pieces of conventional CCFL, 2 pieces of LED back light and 4 pieces of FPC drivers. The driver chips have multiplex scan logic; they are connected to the LED and LED anodeFPC drivers supporting the multiplex scan of CCFL and LED.

A typical LCD working principle is based on the electric field between special liquid crystal molecules. An electrostatic field is generated between the two sides of the LCD cell and caused a twist in the liquid crystal molecules which in turn, affects the polarization of the light passing through it. The light then passes through the polarizer which filters out the light with a polarization other than the one filtered out by the analyzer. As a result, the analyzer, which determines the amount of light that passes through, provides the effect of creating different levels of intensity between on pixel and the next.

An LCD display works in principle by creating patterns of electric forces which controllably twist the liquid crystals. Depending on their compounds, some of these crystals are twisted depending on the imposed voltage, while some require an alternating current to be applied between the common electrode and every single pixel. The pixels act as a switch that is turned on or off by the imposed voltage.

The LK162-12-IY-V-E uses a technique called multiplexing where all the LED and LED anode pins are connected to the controller in a multiplexed arrangement. As the LED and LED anode pins are continually switched, the voltage is only applied to the LED and LED anode pins relative to each segment. This means that all the segments can be lit simultaneously using one common voltage supply.

Conclusion

The LK162-12-IY-V-E is a widely-used numerical LCD display module with a wide range of features and an efficient working principle. Its multiplex scan technique allows for dual color display and low power consumption, making it perfect for many industrial applications. With its cost-effective design, it is an ideal choice for those looking for a reliable, versatile display module.
