An LED display typically consists of an LCD (Liquid Crystal Display) panel and an LED (Light Emitting Diode) based backlight panel. The LED backlight panel acts as a source of light and illuminates the screen, while the LCD panel acts as a picture generating system that controls the amount of light passing through it to create pictures on the screen.

A touch screen works as both an input and an output device. You view the options available to you on the screen (output) and use your finger to touch the option you want (input).

OLED displays consists of organic semiconductor compounds that emit a bright light on the passage of electric current through them. Therefore, OLED displays are considered as self-illuminating types of displays. These displays do not require backlight panel with LEDs.

Both LED (Light Emitting Diode) and OLED (Organic Light Emitting Diode) are popular display technologies used in various electronic devices like TVs, monitors, laptop screens, etc. However, they are completely different from each other in several aspects like technology, construction, energy efficiency, thickness, and more. The most fundamental difference between LED and OLED is in their working, i.e. LED uses backlights for its operation, while OLED uses self-illuminating organic compounds that produce bright light on the passage of electric current. In this article, we will explore all the significant differences between LED and OLED. But before discussing the differences, let us first briefly discuss some basics of LED and OLED display technologies. What is LED? LED stands for Light Emitting Diode.

The two layers are kept apart by tiny bumps (or spacers) placed at regular intervals. When the screen is touched, the plastic deforms so the two conductive films meet and, by measuring the resistance of both layers at their point of contact, it's possible to get an accurate measurement of the touch position.
