Difference Between Dell IPS and Dell WVA

With the introduction of new technology in the display, LCDs became popular and multi-purpose as it was used in monitors, laptops, TV, cell phones, and various other places. LCD has two different panels of display that is IPS and WVA. The most popular manufacturing company is Dell.

Dell IPS vs Dell WVA

The main difference between Dell IPS and WVA is that Dell IPS has parallel alignment while Dell WVA has vertical alignment type in the panels. Dell IPS panels have ‘glow’ while Dell WVA panels have higher black levels, lower backlight bleed, and less glow. Dell launched IPS technology way before it launched the WVA technology in its panels.

DELL IPS vs WVA

The Dell IPS panels were first launched in the year 1993. The earlier models with IPS technology were slower and had fewer features. The color output is of superior quality. The Dell IPS models are best for users who are ready to splurge some extra bucks and want top-notch quality displays.

While Dell WVA panels were first launched in the year 2005. The color output is of comparatively lower quality than IPS. The Dell WVA models are best for customers who want superior display quality under the affordable section.

What is Dell IPS?

The full form of IPS is In-Plane Switching. It is just like other LCD monitors. It operates on voltage which controls the liquid crystals and their alignment. The name in-plane is derived from the orientation of the liquid crystals inside the monitor. The crystals are placed parallel to the substrates of glass.

Conventionally, the liquid crystals are placed in a twisted manner which allows the maximum of light to pass through. However, IPS follows a manner in which the crystals are rotated. This not only allows and modifies eyes the amount of light but also offers other benefits. The screen resolution is around 165 Hz. The panels have a high response or reaction rate.

The Dell panels of IPS have a middle ground technology. The panels are known for their best color performance and excellent view from various angles. The panels provide top-end color output, Hence it is widely used for professional work which involves excellent color gamut.

The Dell panels with IPS technology offer a moderate contrast ratio. The ratio starts from the range of 700: 1 to 1500: 1, depending upon the model type of the parent company Dell. The Dell monitors with IPS technology have the technology mentioned in its products as the technology has various features and the customers often make a choice based on the technology.

What is Dell WVA?

Dell WVA stands for Wide Viewing Angle. The manufacturing company launched the WVA technology in its panels in the year 2005. The color gamut coverage offered in Dell WVA panels is about 125% sRGB. The screen resolution is around 250 Hz in most models with WVA technology.

The viewing angle provided in WVA panels is wide. However, users experience a drop in the quality of pictures while viewing from different angles. It caters to a higher contrast ratio. The panels of Dell have a range of contrast ratio which usually starts from 2000:1 to 4500:1. The contrast ratio is about three times better and superior to the panels of Dell IPS.

Polarised light can pass through the cells that lie in a perpendicular direction to the initial blocks of light. Such a process can create a black state and result in no display. Upon application of electric current, the cells align in a horizontal manner which allows the light. This allows the picture to display on the panel. Dell WVA panels have a superior black uniformity provision.

Dell WVA panels have a lower color range comparatively. The response time is also slower. The rate of response lies in the range of 4 to 8 ms depending upon the model of the parent company. WVA panels would provide a moderate experience while gaming. The Dell WVA panels are best for customers who are on a tight budget and are looking for affordable options.

Main Differences Between Dell IPS and Dell WVA

  1. The Dell IPS panels are suited for color-critical professional work while the Dell WVA panels are not well suited for color-critical professional work.
  2. The lower range of contrast ratio of Dell IPS panels starts from 700:1 or 900:1 while the lower range of contrast ratio of Dell WVA panels starts from 2000:1.
  3. The Dell IPS panels have a bit range of 6 to 10 while the Dell WVA panels have a bit range of 8 to 10.
  4. The Dell IPS panels provide 95% sRGB gamut coverage or less while the Dell WVA panels provide around 125% sRGB gamut coverage.
  5. The reaction rate of Dell IPS panels is 3 to 7 ms while the reaction rate of Dell WVA panels is 4 to 8 ms.
  6. The panels of Dell IPS offer around 165 Hz while the panels of Dell WVA offer around 240 Hz.

Conclusion

Both the panel types have a similar refresh rate. The early panels of Dell were typically slow and had fewer features. With the introduction of IPS and WVA panels, the speed and reaction time has considerably increased. Both the panel types are best for gaming as they provide excellent color quality and the fastest transition time.

Both the panel types use different technology and have distinct strengths and weaknesses. The technology is apt to cater to different needs and demands among the customers. It is essential to evaluate all the parameters of the Dell panels before making a final choice of decision.
