Tv audio bar1/9/2023 ![]() When an OLED panel depicts black, the pixel is completely switched off which means it produces no light whatsoever for ‘true blacks’. OLED, by comparison, is capable of infinite contrast. It can be distracting and if the bright elements are close to the black bars at the top and bottom of a screen then it can ‘bleed’ into those areas. More LEDs mean more precise control over brightness and black levels, which can improve the screen’s contrast performance, enhancing the difference between the brightest and darkest part of the picture for a more striking image.īut blooming, which is a halo or cloud of light around a bright object, is still an issue, especially with screens that have a fairly low LED count. When it comes to brightness Mini LED can, and often does, blow OLED out of the water.īut while Mini LED amps up the brightness of LCD LED screens, the backlight can suffer from the same faults, though to a less extreme degree. We’ve tested Mini LED TVs that have gone past the 2000 nits mark, and in some modes even hit 4000 nits (for 8K TVs). Premium OLED and QD-OLED screens such as the LG G2 OLED and Samsung S95B QD-OLED hit just above 1000 nits, while cheaper and older models average around 500-600 nits of brightness. The same line of thinking applies to TVs whereby the brightness of a Mini LED panel copes better with brightly lit rooms than OLED where that screen is best suited to viewing in dimly lit rooms. Samsung QN94A Mini LEDįor mobile devices, being brighter means able to resist the glare caused by sunlight better, though Mini LED has only been used in tablets so far, such as some iPad models. ![]() Where is this advantage useful? Mainly with HDR content or use with mobile devices in bright sunlight.Ī higher level of brightness with HDR content allows for a wider range of colours and tones to be depicted, making for what’s arguably a more accurate and true-to-life image. LED LCD screens already go brighter than OLED, and Mini LED extends that lead further. It can control the brightness down to the individual pixel.Ī pixel that’s ‘on’ can sit next to a pixel that is ‘off’, allowing OLED screens to have exceptional control over black levels and contrast. This gives OLED what’s commonly referred to as ‘pixel level dimming’ wherein it doesn’t need a backlight to tell the screen which parts should be bright and which parts should be dark. In OLED screens each pixel is self-emissive, which means it can produce its own light when an electrical current is passed through it. OLED stands for Organic Light Emitting Diode. It depends on the size of the screen and how much control over the backlight a manufacturer wants to exert (as well as price, of course). Some TVs have hundreds of these Mini LEDs, others can have as many as thousands. The more LEDs there are, the more dimming zones there can be, which allows for greater control over brightness, contrast and black levels. The ‘mini’ part refers to the size of the LED used in the display to produce the light seen on screen.īy miniaturising the LED form factor, it allows for more LEDs to be squeezed into the display. ![]() Mini LED is an advancement of LED LCD backlighting technology. So, is one better than the other, and if so which one? Ultimately it’ll be determined by what your needs are. They’re used across various devices such as smartphones, tablets, smartwatches and TVs, but we’ll training our attention more towards TVs. ![]() These two types of panel are relatively new, and both have their advantages and disadvantages. But some knowledge will assist in making a better choice in finding the TV that will be the mainstay of your living room for years. ![]() Acronyms such as LCD LED, OLED and Mini LED may have already seeped into your consciousness.įor those who aren’t into TV tech, you’d probably take little notice of what these various technologies mean or what effect they may have on your viewing experience. If you’ve been in the market for a new TV recently, you’ve possibly come across various terms during your search. ![]()
