What is LED Like Super National 22
A light-emitting diode (LED) is a semiconductor device that emits light upon stimulation. LEDs are used in many applications where other lighting devices are unsuitable. Common uses include traffic signals, interior, and exterior house numbers, automobile taillights, flashlights, medical equipment, and indicator lights.
Led lights have been around since the early 1900s. Since then, led technology has improved, allowing them to become smaller, brighter, longer-lasting, and less expensive.
Refresh Rate
Refresh rate refers to how many times per second your screen refreshes. This is measured in hertz (Hz), and the higher the refresh rate, the smoother the image appears. 1080p displays run at 60 Hz, but some newer TVs are now running at 120 Hz.
Resolution
Resolution refers to the number of pixels per inch (PPI) on your screen. This is measured in dots per inch (DPI). A higher resolution means more details and therefore a clearer picture. Most people would agree that a high-definition (HD) display has a minimum of 720p while 4K displays are around 4000 PPI.
