[Learn Display] 26. Liquid Crystal

Liquid Crystal, an essential material that composes LCDs, has properties of both fluidities of liquid and crystallinity of solid. Let’s figure out the role of liquid crystal in LCDs, the display technology that utilizes light transmission based on the modification of liquid crystal. As the name suggests, Liquid Crystal is a substance that blends the properties of liquid and crystalline solid states, serving as the essential materials of LCDs. Liquid Crystal was first discovered in 1854 and was named as ‘Liquid Crystal’ by Friedrich Reinitzer, an Austrian biologist, in 1888. Ever since liquid crystal was discovered, there has been a lot of research on modifying its state by applying electricity stimulation. After presenting the fact that liquid crystal exhibits unique optical properties in Nature in the 1960s, liquid crystal is widely used in a number of optical applications and finally commercialized. As mentioned earlier, the liquid crystal has optical properties that transmit light and property that reacts to electric current and modifies its alignment. Therefore, liquid crystal is used for passing through light or adjusting the amount of light. When…

[Learn Display] 25. Organic Layers (HIL, HTL, EML, ETL, EIL)

Organic layers in the structure of OLED display serve as a light emitter, consist of an emissive layer and ones that support light emission. The latter, supporting layers including Hole Injection Layer (HIL) and Hole Transport Layer (HTL) as well as Electron Injection Layer (EIL) and Electron Transport Layer (ETL), enable easier injection and transport of holes and electrons into Emissive Layer (EML). OLEDs are a type of display that emits light when electricity flows: Once electrons and holes are combined, it results in light emission. Electrons that migrate from the cathode and holes from the anode are transported into and combined in the Emission Material Layer (EML). To work this out, injection layers help electrons and holes quickly inject, while transport layers support fast transport of electrons and holes. With this configuration, the injection layers facilitate the injection of holes and electrons, while transport layers help them transport into the EML.

[Interview] Behind the Scenes│Interview with Samsung Foldable OLED Developers

Samsung Electronics’ Galaxy Z Fold3, Galaxy Z Flip3 have been sweeping the industry with upbeat reviews, with the most eye-catching innovation being display upgrade. With ten years worth of hard work dedicated to this innovation, this article will cover the ‘behind the scenes’ stories of developers who carefully designed foldable into reality, with the latest third attempt being Galaxy Z Fold3.   Q1. What was the key objective for foldable panel development in 2021? <Sung-Un Park, Product Development PM>We wanted to highlight the best parts about foldable devices – which is still a fairly novel and unfamiliar technology to most people – by accentuating tangible innovations. Think of low-power technology, big screens, and enhanced user experience with S-Pen support!  Q2. Tangible innovation sounds fascinating. Why do you use that specific term? <Sung-Un Park, Product Development PM>To match public expectations of foldables, we focused on realizing display technologies that consumers could see and feel the difference themselves since display is one of the key elements that affect user satisfaction for smartphones.   Q3. Tell us more about low-power technology, one of the key…

[Learn Display] 24. Holography

Holograms have been a staple of sci-fi films, but how does it work? Hologram images come to life with the combination of constructive interference principle, a wave property of light, and an LCD panel. This article introduces the principle of holography, an essential technology to create hologram images. Holography is a display technology that reconstructs stereoscopic videosžimages using the light interferences phenomenon created when light waves meet. ※ Hologram: Videos and images generated with holography technology Holography utilizes laser light sources to reconstruct 3D images. Lights from the lasers meet to create a point, and a myriad of such points are combined to form the total 3D scene. A laser with coherent light is used as a backlight source, while pixels of a display panel are calibrated and controlled to let lights meet at a given point in space to generate 3D scene points based on the constructive interference principle.   ※ Constructive interference: Constructive interference occurs when two waves in the same phase add together in superposition, creating a wave with cumulatively higher amplitude

[Learn Display] 23. Light-Field Display

Light field display reproduces a 3D image visible to viewers without the need to wear glasses. This technology uses a display and optical devices to display stereoscopic images by varying intensity and direction of light.  Unlike conventional displays, the light field display can create natural 3D images as it demonstrates the depth and sides of the projected object depending on a viewer’s perspective. The light field display is gaining traction as one of the next-generation displays as it is open to various applications by converging with AR technology.
