An explanation of LCD Panel Technology

Several different types of paneling techniques are used to produce LCD monitors. These include the budget TN paneling to more expensive and professional panels, such as the S-PVA and S-IPS panels. Generally, a common person is unaware of the paneling technique used in his or her LCD.

Most individuals choose the monitor based on its size and cost. Although, cost is an important consideration, it is important to know the pros and cons of the various types of panels. Moreover, users must be able to distinguish between the different types of panels before making their purchase.

 

IPS Paneling Technique

The S or H In Plane Switching paneling is commonly assumed to be of the highest quality in the LCD technology. These provide high image qualities, accurate colors, and view angles, but are very expensive. These monitors are appropriate for graphical designers and other application users who need consistent and accurate colors. S-IPS paneling provides the best view angles amongst all the numerous LCDs, which can go up to 178 degrees. The time taken for responding by the S-IPS monitors is satisfactory that ranges from six ms and sixteen ms along with the control paneling. This speed is a little lower than the TN paneling, which is an important consideration for game lovers. The fast games may blur or provide ghost-like appearance in case the responding time is more than eight ms. These types of monitors should suffice until such a time when the OLED monitors become commercially feasible.

The S-IPS paneling is identifiable through the slight purplish color when users glance through wider angles. Only limited manufacturing companies produce this type of panels when compared to the other types available, which make these LCDs very expensive. A new variety within the S-IPS paneling is the H-IPS paneling. This provides a distinct pixel architecture providing an improvement in the contrast ratio and lowering of the pixel patches enabling a higher picture quality.

 

VA Paneling Technique

The vertical alignment technique, which include S-PVA and MVA are mid-segment LCD paneling. When compared to TN panels, these provide better color quality and wider view angles; however, these are marked with reduced responding time. Although, these are similar to the S-IPS panels, and provide a wider viewing angle and better color representation, these features lack in comparison to S-IPS. The responding time is significantly lower than the S-IPS or TN panels with several complaints on input lags, which does not make the VA paneling an appropriate option for fast games.

These types of panels are benefited with higher contrasting ratio in comparison to other types, which provided improved black levels. However, the major drawback of the VA panel is the shifting of colors. This implies that the color varies when the same image is viewed from two different angles, which creates uneven brightness across the screen. This drawback prohibits several users from even considering a VA panel monitor while other users may be indifferent to this color variation. The color shifting leads to losing shadow details in dark settings when viewed from the middle. Several companies manufacture these types of panels, which makes these easier to buy. The panels provide a higher image quality in comparison to TN panels at an affordable price that is lower than the IPS panels.

 

TN Paneling Technique

The twisted nematic paneling technology is the commonest technology used to produce LCD monitors. These panels are competitively priced with faster responding time that makes it appropriate for fast games. The responding time ranges between two ms and five ms. However, the reproduction of the colors, angle viewing, and contrasting ratio are one of the worst in these types of panels. Because the TN panels are six-bit, these cannot display the more than sixteen million colors provided by the 24-bit true colors. The panels are able to provide a mimic of the 16.7 million colors in the eight-bit panels with the use of dithering; however, the results leave much to be desired. These panels are very popular with the regular computer users due to their lower prices and are one of the most widely used LCD monitors available in the market.

 

Summarizing LCD Paneling Technology

The S/H-IPS paneling is assumed to be the best types of panels though these are extremely costly and are manufactured in limited quantities. These are high-end but expensive.

The S-PVA and MVS paneling provide higher reproductions of colors and view angles in comparison to the TN paneling. However, the responding time is minutely lower than the TN and S-IPS paneling, providing better contrasting ratio, but have color moving problems, and a lag in the input. However, these are easily available in compared to the S-IPS paneling, which makes it mid-ranged at a fair cost.

The TN paneling is the cheapest with the quickest responding time. However, these panels provide inferior reproduction of colors, contrasting ratio, and view angles. The TN panels are lower end but cheap.
