LG Display unveils 23-inch 240 Hz IPS panel

24 Nov 2010 | Rasmus Larsen |

LG Display today announced that they have developed a 23-inch 240Hz IPS panel for PC monitors and HDTV. The IPS panel utilizes 120 Hz and scanning backlights to improve response time significantly.

The industry have been engaged in a heated race to improve the motion picture response time (MPRT) for many years. Now LG has a new, innovative IPS panel ready.

It’s a new 23-inch IPS LCD panel with “240 Hz”, combining 120 Hz technology (refreshes 120 images per second) and scanning backlights where a scanning line scrolls from the top of the panel to the bottom; unnoticeable to the human eye. Scanning backlights is utilized in most new high-end LCD-TVs and reduces the visual perception of blurring from a LCD panel because the sample-and-hold effect is nullified.

Even though LG mentions a 120 Hz frequency it’s not clear if LG is talking about a frame interpolation technology that calculates new image frames or a true 120 Hz processing panel, similar to the 120 Hz TN panels. No 3D support is mentioned in the press material either which could support the theory that it's a frame interpolation technology.

LG Display says that the panel is in mass production now and sees it as a big step in the PC monitor industry, claiming:
- “In the past, monitors in the 20-inch range were mainly used for word processing, but expansion of the multimedia environment has extended their application to games, videos, and even second TV sets. The 23-inch 240Hz LCD panel from LG Display should allow consumers to enjoy vibrant images and picture quality they expect from a large-size TV on their monitor or a smaller, second TV.”

Mr. Ha Hyun Hwoi, LG Display’s Vice President and head of the IT Business Unit, noted,
- “This product was designed to meet expectations of consumers who are already used to superior picture quality and high motion picture response time. LG Display will continue with efforts to introduce products that deliver new value to our customers and consumers.”

LG has given no indication of coming PC monitors with the new 240 Hz panel yet. We will keep you updated with more information as soon as possible.
