really just an LCD display. It's just that it uses LEDs for backlighting instead of CCFLs. Now there are a few different ways that LEDs are implemented to create a backlight. One way is by placing white LEDs along the edge, usually across the top of the LCD panel, and then using a diffuser to evenly distribute the light across the surface of the display. This is known as edge-lit backlight using white LEDs, or just EL-WLED. Sometimes just shortened to WLED. And it's probably the most common implementation of LED backlighting. Another implementation is to cover the entire backsideof the LCD with an array of white LEDs. This is known as full-array WLED backlighting. The last implementation we need to talk about here also uses an array of LEDs. However, instead of using white LEDs, a special type of LED is used called an RGB LED. A single RGB LED is capable of producing red, green, and blue light. So instead of using red, green and blue filters,the LED simply changes color. And because of this, RGB LED backlighting can produce extremely accurate and very vibrant colors. But this quality comes at a cost. RGB LED backlit monitors cost a lot more than monitors that just use standard WLED backlighting. Now, at this point, it's important to remember that the backlighting only provides illumination. It doesn't actually create the images on the screen. The component responsible for creating the images is the actual LCD panel itself. OLED Display 7:29-9:20 So at this point, we're done talking about LCD and LED monitors, and now we're going to talk about OLED displays. Now OLED stands for organic light-emitting diode. OLED monitors use an organic compound that lights up in response to an electrical current. Basically, they produce their own light.Because they produce their own light, no backlight is needed. And the way they're constructed allows OLEDs to be made very, very, very, thin. Now an OLED screen consists of several layers. We have a metal cathode. We have a glass panel that contains organic emitters, the OLEDs. We have an anode layer, and then an external screen, which is typically made out of glass. When a current flows between the cathode and the anode, the OLEDs react and produce light. Now the rate at which OLED screens can switch pixels on and off is extremely fast. That's one of their key benefits. In fact, OLED screens can turn pixels off and on about a thousand times faster than the very fastest LCD. OLEDs also use a lot less energy than other display devices, and they can achieve very accurate colors. Another cool thing about OLED displays is that they're very flexible, depending upon what they're made out of, they can be made so flexible that they can even be folded. Now this quality, of course, comes at a cost. Now OLED displays, as you might guess, are a lot more expensive than other types of displays and they also have a reputation for not lasting as long as other types of displays. The organic compound that's used to create an OLED loses its luminescence a lot faster than a traditional LED does. In addition, the blue LEDs have a reputation for losing their luminescence faster than the red and the green OLEDs. So over time, the OLED display's

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
