What is True Black?
Before jumping into whether IPS LCD can achieve true black, it’s crucial to understand what “true black” actually means. True black is often described as the darkest shade of black, where no light is emitted from the display. In practical terms, true black results in a stark contrast against lighter colors, enhancing the overall depth and vibrancy of an image.
How Does True Black Differ Across Technologies?
To appreciate the limitations and capabilities of IPS LCD technology, it’s essential to compare it with other display types such as OLED (Organic Light Emitting Diodes).
OLED vs. IPS LCD: The Black Levels Showdown
In OLED technology, each pixel emits its own light. When an OLED pixel is turned off, it doesn’t emit any light, resulting in true black levels. This fundamental characteristic makes OLED displays outstanding for contrast performance.
On the other hand, IPS LCDs utilize a backlight that is always on, even when displaying black hues. As a result, the black levels in IPS LCDs are never truly black but are instead shades of dark gray, constrained by the brightness of the backlight.
The Science Behind Black Levels in IPS LCDs
The black levels in IPS LCD can be influenced by multiple factors, including:
Backlight Technology
The type of backlight used can significantly affect the black levels of an IPS LCD panel. Traditional LCDs rely on cold cathode fluorescent lamps (CCFL), while modern displays predominantly use LED backlighting.
Types of Backlighting
- Full-Array Local Dimming: This technology allows certain areas of the backlight to dim independently. While it provides better control over black levels, it’s still unable to reach true black as achieved by OLED.
- Edge-Lit LED: This is where LEDs are positioned along the edges of the display. It usually results in less effective black levels compared to full-array backlighting.
Even with advanced technologies, IPS LCDs can only achieve a deep gray, not a true black.
Contrast Ratio: A Key Indicator
The contrast ratio is a critical metric when evaluating display performance. It’s the ratio between the luminance of the brightest white and the darkest black the display can produce.
Most IPS LCDs have a contrast ratio around 1000:1, which, while respectable, simply doesn’t match the infinite contrast ratio available in OLED displays. This disparity is significant when it comes to displaying darker scenes, where the IPS display may struggle to differentiate between very dark shades.
Pros and Cons of IPS LCDs
As with any technology, IPS LCDs come with their own set of advantages and disadvantages. Here’s a closer look:
| Advantages | Disadvantages |

What is IPS LCD technology?
IPS LCD (In-Plane Switching Liquid Crystal Display) is a type of display technology commonly used in televisions, computer monitors, and mobile devices. It is known for its ability to provide wider viewing angles and more accurate color reproduction compared to traditional LCD technologies. In an IPS LCD panel, liquid crystals are aligned in parallel, allowing light to pass through more effectively and providing a more consistent image regardless of the angle from which it is viewed.
Additionally, IPS displays typically have better color consistency and higher color fidelity, making them a favorite among photographers, graphic designers, and anyone who values accurate color representation. However, one downside of IPS technology is that it has limitations in achieving true black levels, which leads to the common misconception about its performance in displaying deep blacks compared to other technologies like OLED.
Does IPS LCD display true black?
No, IPS LCDs do not display true black in the same way that OLED displays do. The reason for this is that IPS LCDs use a backlight to illuminate the liquid crystals, which means that even when the pixels are supposed to be displaying black, some light is still emitted from the backlight. This results in a dark gray instead of a true black, leading to less contrast in dark scenes.
The inability to achieve true black can affect the overall viewing experience, particularly in darker environments or when consuming media with high contrast. While IPS LCDs have improved over the years and can produce reasonably deep blacks, they still cannot match the performance of OLED technology, which is capable of turning off individual pixels to achieve true black.
