A recent iSuppli study revealed the challenges encountered by companies interested in mass-producing AMOLED TVs and suggested that only a few thousand such television sets will be sold this year, with production expected to increase gradually over the next couple of years.
The following comparison chart shows the differences between AMOLED TVs and TV sets using other technologies, both when it comes to certain specs and features but also when it comes to prices:. By Chris Smith. Each pixel is activated directly: A corresponding circuit delivers voltage to the cathode and anode materials, stimulating the middle organic layer.

On a technical level, what differentiates these two prevalent screen technologies? Well, lets start with the basics. Both screens are made up of Pixels. A pixel is made up of 3 sections called sub-pixels. The three sections are red, green and blue primary colors for display tech. To make a certain color, each pixel lets certain amounts of light through each pixel at different intensities, showing the color on your screen.
Where you start seeing differences emerge, is how the light is generated in each screen. Today, premium-tier smartphones make use of flexible OLED displays. Although, there are some concerns over how many times a display can flex and bend before breaking.
Rather than using individual light-emitting components, LCD displays rely on a backlight as the sole light source. Although multiple backlights can be used across a display for local dimming and to help save on power consumption, this is more of a requirement in larger TVs.
White light is a mixture of all other visible colors in the spectrum. Therefore, LCD backlights have to create a pseudo white light as efficiently as possible, which can then be filtered into different colors in the liquid crystal element. Most LCDs rely on a blue LED backlight which is filtered through a yellow phosphor coating, producing a pseudo white light.
All combined, this allows an LCD display to control the amount of RGB light reaching the surface by culling a backlight, rather than producing colored light in each pixel. This wide variation in the way that light is produced has quite a profound difference to the user experience.
Color gamut is often the most talked-about difference between the two display types, with AMOLED providing a greater range of color options than LCD, resulting in more vibrant-looking images.
OLED displays have been known for additional green and blue saturation, as these tend to be the most powerful colors in the sub-pixel arrangement, and very little green is required for white light. Some observers find that this extra saturation produces results that they find slightly unnatural looking.
Although color accuracy has improved substantially in the past few years and tends to offer better accuracy for wider color gamuts like DCI-P3 and BT
