[Learn Display] 30. Substrate

Display substrate refers to a material that forms the necessary basis for manufacturing in each display process, such as LCD and OLED. To compare the substrate to the construction process, it is similar to compacting a construction site in advance before groundwork is done. Most display substrates are made of glass, and have a very thin and flat shape of less than 1mm. Taking production efficiency into account, the large-sized substrate is put into the manufacturing process as it is. After passing through such a process, the fabricated substrate is cut into the appropriate size required for the final product. In case of LCDs, a glass substrate is used to build on a TFT (Thin Film Transistor) layer that controls liquid crystals and a color filter layer. Similar to the LCDs, OLEDs also use a glass substrate to fabricate TFT and the encapsulation glass to protect the self-emissive organic layer from contacting external air and moisture. While such ‘Rigid OLEDs’ use glass to produce substrate, ‘Flexible OLEDs’, which have lately been in the spotlight, utilize polyimide (PI) material for the…

[Learn Display] 29. Backlight Unit

Backlight Unit is one of the essential components of the LCDs. There are two types of Display: One is an emissive type that can be self-luminous, and the other is a non-emissive type operated utilizing an external light source. LCDs, unlike OLEDs, do not have an illuminant source, so they require the help of separate light to generate an image on the screen. In a nutshell, the backlight unit is the part that illuminates light evenly in the entire panel area for the display screen to be turned on. Backlight unit, also known as the acronym ‘BLU,’ is located on the very bottom side of an LCD panel. In the LCD structure, when the light comes out from the backlight unit, it passes through a liquid crystal and is tilted to the desired alignment to adjust the amount of light. Which color will be produced is determined after passing through a color filter composed of Red, Green, and Blue. For example, if the tilted liquid crystal completely blocks the passage of light, the display will show black color. However, if…
