What is LCD or LED display? And Types of display....

A liquid display (LCD) display is a flat-flat display or another electronic device that uses fluorescent illumination properties of liquid crystals combined with polarizers. Liquid crystals do not emit direct light, instead of using a backlight or signal to produce images in color or monochrome. LCDs are available to display conflicting images (as in the case of a typical computer objective) or edited images with low-resolution content, which may be displayed or hidden. For example, pre-set words, digits, and displays of seven components, such as a digital clock, are all good examples of display devices. They use the same basic technology, except that the irresistible images are made with a matrix of small pixels, while other displays have larger features. LCDs may be (positive) or closed (negative), depending on the configuration of the polarizer. For example, a characteristic LCD with background light will have black backlight color, while a negative LCD character will have a dark b...

What is an LED used for? And who invented it

Led stands for light-emitting diode which concentrates photons particles in a semiconductor and releases them in a beam of light form . Then we called it Light rays or light beam. Now in this blog, we will try to understand how it works, what it is used for it, and at last how it produces such different colors and a lot more in this blog 1st of all let's try to understand. What is an LED used for? LED, with a diode full of light, electronic, a semiconductor device that emits infrared or visible light when charged with electrical power . Visible LEDs are used on many electronic devices such as indicator lights, in cars such as rear windows and brake lights, and on billboards and signs such as alphanumeric displays or in full-color posters . Infrared LEDs are used in autofocus cameras and television remote controls and also as illuminating sources in fiber-optic communication systems . A conventional lamp emits light with incandescence, a substance in which electr...
