There are many versatile display technologies that fulfil the different requirements of the various applications.
FREMONT, CA:Today people are surrounded by gadgets with displays in their daily lives, and they spend a lot of time staring at screens, whether it is on smartphones, computers, or televisions. Apart from these high-resolution active-matrix displays, people are also used to looking at low-resolution displays like alarm clocks, smart thermostats, and kitchen appliances.
Even while driving, people rely on displays, from the car dashboard to the infotainment system, the amount of space dedicated to displays in cars is rapidly increasing.
These display systems have unique needs, and display device designers must choose from a wide range of display technologies. To select the best technology, they must first determine the display parameters that are most appropriate for the application in question. Here are some of the technologies that display device designers use.
Display technologies
Below is a list of some of the most crucial display technologies from which display designers can choose.
LCD
LCD displays used to be slow and lacked a decent contrast ratio and color gamut at every viewing angles. These issues have been addressed, and LCDs now account for over 90 percent of all displays sold. The color gamut of an LCD display is determined by the color filter used and is usually not as comprehensive as the OLED display. With the advent of QDOT and dual-cell technology, it is possible to achieve color and contrast efficiency like OLED.
OLED displays
OLED displays have been developing for quite some time. Their weakest point, particularly for the blue emitters, has been their lifetime. The lifetimes can get much shorter due to the high brightness. There are two kinds of OLED displays: RGB OLED and WOLED.
RGB OLED displays use a Fine Metal Mask (FMM) to pattern the red, green, and blue OLED material and emit light when necessary.
QDOT OLED displays
Many big companies are actively investing in QDOT OLED display technology for massive displays to solve the shortcomings of WOLED. On top of a blue OLED backplane, photoluminescent red and green quantum dots are printed. Two of WOLED's flaws are addressed with this method.
Flex OLED displays
Most OLED displays are built on a glass substrate because glass is an excellent low-cost oxygen and water barrier material, which is critical for OLED. The majority of flexible OLED displays are produced on a polyimide substrate, which needs installing a barrier layer, raising the cost.
