LCD technology issues

LCD displays survive challenges and adversity

LCD is a display that has survived through hardships, ups and downs, and battles.
Although it had established itself to some extent, its weaknesses were easily seen by latecomers, such as displays that could not produce their own light, slow displays due to slow and poorly balanced liquid crystals, and displays that appeared different depending on the viewing angle.
However, despite the challenges of these displays, they survived and continued to develop and establish themselves.
The slow response time was overcome by developing faster liquid crystal displays, and the viewing angle issue was resolved by improving the liquid crystal display's operating mode.
Color and image quality have been improved with LED backlighting and the application of quantum dots, while resolution has reached its peak through the active adoption of semiconductor processes. In the evolution of LCD, we witness the culmination of dedicated efforts and proactive outsourcing.
The upcoming showdown with OLED and the evolution to true QLED are exciting, and the competition between these displays is exciting.

LCD, a display that embodies the colors of nature

No matter how advanced displays become, they cannot perfectly reproduce the natural colors God gave us.
Just getting closer.
In fact, the reason LCD was able to revive its competition with OLED was the improvement in color reproducibility through quantum dots.
Quantum dots are semiconductor particles measuring a few nanometers in diameter. Their emission wavelength varies depending on particle size, and they possess high color purity and stability. Based on this, LCDs have achieved color reproducibility exceeding that of OLEDs.
Controversially called QLED, it competes fiercely with the near-perfect OLED technology.

The third story, "Understanding Liquid Crystal Displays"

This book explains in detail the liquid crystal display (LCD), which has been the mainstream until now.
Even as the era of OLED, QLED, and micro LED arrives, LCD will remain. This is because LCD possesses its own unique history, characteristics, applicability, and economic feasibility.
This book introduces the development of liquid crystals, starting from their discovery in the 1800s, through their application as displays, and from electronic calculators to TVs.
This course explains the classification of liquid crystal molecules, their electro-optical properties, and the principles applied to displays. It also discusses the basic structure and operating mechanisms of LCDs, as well as the backplane and thin-film transistors used for driving them. It also provides an easy and engaging explanation of the components that make up an LCD, including polarizing plates, alignment layers, color filters, backlights, and drivers.
Terminology and descriptions of operating characteristics and performance continue to revolve around liquid crystal displays and operating modes, and the LCD manufacturing process is also evolving into a thin-film transistor substrate, color substrate, liquid crystal cell, and module configuration. The LCD era is reaching its peak.
But LCD still survives and is targeting future displays.
This book contains interesting stories about these LCDs in an easy and fun way.

"Display Story" to be published in five volumes

The 'Display Story' series will be published in a total of 5 volumes.
Volume 1, "Understanding Displays," covers the origins, evolution, history, and classification of displays, and provides an easy-to-understand, core explanation of display technologies.
Volume 2, titled 'Understanding Display Common Sense and Knowledge', covers basic theories and terminology common to all displays.
Volume 3, titled 'Understanding Liquid Crystal Displays', describes in detail the LCD, which has been the mainstream until now.
Volume 4, titled 'Understanding Organic Light-Emitting Diodes', details OLED, which is establishing itself as a new mainstream technology.
Volume 5, titled 'Learning about Organic Light-Emitting Diodes and Quantum Dot Displays', describes OLED in more detail and explains QLED, the next-generation display.
