Introduction to LCD, OLED Character, and Numeric Displays

Display Modules are components of many electronic devices and are used to present textual and graphical information to device users. The two common types of display modules include LCD (Liquid Crystal Displays) and OLED (Organic Light Emitting Displays). LCDs harness the properties of an electrically controlled liquid crystal material to transform light into various shapes. OLEDs use the organic materials found in most transistors to create bright displays with extremely low power consumption. LCDs and OLEDs are further broken into two categories: Character and Numeric.

Applications of LCD and OLED Character Displays

LCD and OLED Character Displays are used in a variety of applications. Medical device manufacturers place a high priority on ease-of-use, which LCDS and OLED Character Displays provide through the clear, legible text. Character displays are also the display of choice for precision instruments that require the ability to read numbers of varying lengths accurately. Additionally, LCD and OLED Character Displays are used in signage and industrial control panels that require a wide viewing angle and high contrast.

Working Principle of LCD and OLED Character Displays

LCD Character Displays are constructed of liquid crystal material sandwiched between two polarizing sheets of glass. The top glass sheet is transparent while the bottom glass sheet is coated with transparent electrodes. Applying an electric voltage to the electrodes causes the liquid crystal material to “twist” and block or pass the light depending on the polarity of the voltage. By varying the polarization of the electrodes, the liquid crystal material changes shape, creating the desired text or graphics on the display.OLED Character Displays are constructed of organic compounds that give off light when exposed to electricity. When current passes through the organic compounds, they excite electrons, emit a photon and then return to their ground state. The organic compounds are arranged into pixels that turn on or off to create text and images on the display.

Applications of LCD and OLED Numeric Displays

LCD and OLED Numeric Displays are used in a wide variety of applications, particularly those that require pin point accuracy and reliability. Industrial displays, scientific instruments, GPS systems, and medical devices are just a few of the common applications of LCD and OLED Numeric Displays. Most LCD and OLED Numeric Displays also benefit from lower power consumption compared to traditional LEDs, making them ideal for battery powered applications.

Working Principle of LCD and OLED Numeric Displays

LCD Numeric Displays are similar to LCD Character Displays but are composed of larger pixels that create an individual number of the display. The pixels generally remain static and the numbers are easily read and manipulated by the user.OLED Numeric Displays are similar to OLED Character Displays in that they generate light with an electric current. However, OLED Numeric displays create larger pixels that can be used to form individual numbers. The OLED material is arranged into pixels that can be turned on or off to create the desired numbers on the display.

Conclusion

LCD and OLED Character and Numeric displays are used in a variety of applications. LCD Character displays use electrically controlled liquid crystal materials to create images. OLED Character displays use organic compounds that produce light when exposed to electric current. LCD and OLED Numeric displays use larger pixels to form individual numbers. LCD and OLED Character and Numeric displays provide precision instrument readings, high contrast, a wide viewing angle, and low power consumption.
