What makes lcd better

It has the best contrast ratio of any modern display. Contrast ratio is the most important aspect of picture quality. A high contrast-ratio display will look more realistic than one with a lower contrast ratio. For more info, check out the basics of contrast ratio and why it's important to understand contrast ratio.

This one's easy. There are also small, inexpensive p and even p resolution LCDs. There are no p or lower resolution OLEDs currently on the market. Refresh rate is important in reducing motion blur , or the blurring of anything on screen that moves including the whole image if the camera pans. Cheaper LCDs are 60Hz. Keep in mind, most companies use numbers that are higher than their "true" refresh rate. One of the main downsides of LCD TVs is a change in picture quality if you sit away from dead center as in, off to the sides.

How much this matters to you certainly depends on your seating arrangement, but also on how much you love your loved ones. So if you have a wide seating area, OLED is the better option.

It has brighter highlights and typically a wider color gamut. Its superior contrast and lack of blooming win the day despite LCD's brightness advantage. The smallest triangle circles at corners is what your current HDTV can do. The next largest squares is P3 color. The largest triangle edges is Rec It's an expansion of the colors possible on "standard" TVs. Think richer, deeper and more vibrant colors.

Uniformity refers to the consistency of brightness across the screen. Many LCDs are pretty terrible with this, "leaking" light from their edges. This can be distracting, especially during darker movies. OLED's energy consumption is directly related to screen brightness.

The brighter the screen, the more power it draws. It even varies with content. The LED part just refers to the lighting source, not the display itself. The light of an OLED display can be controlled on a pixel-by-pixel basis. The light from these LEDs is then fired through a matrix that feeds it through the red, green and blue pixels and into our eyes. Brightness is important when viewing content in ambient light or sunlight, but also for high dynamic range video. This applies more to TVs, but phones are increasingly boasting of video performance, and so it matters in that market too.

The higher the level of brightness, the greater the visual impact, which is half the point of HDR. A decent LCD screen might have a contrast ratio of 1,, which means the whites are a thousand times brighter than the blacks.

Contrast on an OLED display is far higher. When an OLED screen goes black, its pixels produce no light whatsoever. OLED panels enjoy excellent viewing angles, primarily because the technology is so thin and the pixels are so close to the surface. Viewing angles are generally worse in LCDs, but this does vary hugely depending on the display technology used.

And there are lots of different kinds of LCD panel. Perhaps the most basic is twisted nematic TN. This is the type used in budget computer monitors, cheaper laptops and some very low-cost phones.

It offers poor angled viewing. IPS is used in the vast majority of smartphones and tablets, plenty of computer monitors and lots of TVs. There are many factors to consider, but the process often begins with one major question: What kind of TV should you get?

These panels are typically composed of two sheets of polarizing material with a liquid crystal solution between them. Think of it as a shutter, either allowing light to pass through or blocking it out. Each of these illumination technologies is different from one another in important ways. CCFL backlighting is an older, now-abandoned form of display technology in which a series of cold cathode lamps sit across the inside of the TV behind the LCD.

The lights illuminate the crystals fairly evenly, which means all regions of the picture will have similar brightness levels. This affects some aspects of picture quality, which we discuss in more detail below. Full-array backlighting swaps the outdated CCFLs for an array of LEDs spanning the back of the screen, comprising zones of LEDs that can be lit or dimmed in a process called local dimming.

While there are some drawbacks to edge lighting compared to full-array or direct backlight displays, the upshot is edge lighting that allows manufacturers to make thinner TVs that cost less to manufacture.

To better close the local-dimming quality gap between edge-lit TVs and full-array back-lit TVs, manufacturers like Sony and Samsung developed their own advanced edge lighting forms. These keep the slim form factor achievable through edge-lit design and local dimming quality more on par with full-array backlighting.

This is accomplished by selectively dimming the LEDs when that particular part of the picture — or region — is intended to be dark. The quality of local dimming varies depending on which type of backlighting your LCD uses, how many individual zones of backlighting are employed, and the quality of the processing.
