| S-IPS/WCG-Panel | |
||||||||
| |||||||||
The new WCG S-IPS Panel (Wide Color Gamut) in sizes 24“, 26“, 27'' & 30'' from LG Display are offered in the aspect ratio of 16:10. They combine advantages of the IPS technology (In Plane Switching) with an all-time intense and vivid colour rendering. This is the case especially for the 24” display with a resolution of 10 bit per colour. • LM220WE4-SLB2 • LM240WU4-SLB3 • LM270WQ2-SLA1 • LM300WQ5-STA1 The additionally offered 22'' Panel (1650x1080) is a so called e-IPS Panel (economy IPS). The sizes 24'', 27'' and 30'' include the latest S-IPS (Super IPS) and WCG technology. Constructive element regarding the WCG technology is pigmented phosphor at the surface of the CCFL tubes. With this technology, the new WCG S-IPS panels from LG Display can cover a NTSC colour space of up to 102%. Compared to this, the percentage for LCD TFT panels with conventional CCFL technology is at 72%. Regarding IPS technology the liquid crystals in every pixel are arranged horizontally. Without driver they are arranged parallel to the glass substrate, the light is blocked, the pixel remains dark (normally black). If the pixel is driven by voltage application, the crystals turn horizontally about 90°. The light can pass the so called “polarisation filter”, the pixel glows. The S-IPS technology (Super In Plane Switching) offers especially compared to TN technology a clearly wider viewing angle in horizontal and vertical direction. The initial advantage of speed of TN panels compared to IPS technology when switching the crystals, could be balanced by using overdrive technologies. Typical response time is 5ms (GTG). Compared to VA technology a considerably lower colour shift (∆u´v´) of S-IPS panels with 0,018 to 0,037 can be noted (related to a standardized viewing angle of 60°) Even more significant the correspondent values of test point Gamma Shift Ratio (GSR) differ. While a S-IPS panel has a measured value of 1% (again related to a viewing angle of 60°) a VA panel falls off about more than 40% in that point of test. Another constructional advantage of S-IPS technology compared to VA technology is ruggedness against touching the surface of the display. While regarding a VA panel the so called “touch flash phenomenon” leads to a brightening of the touched area when touching the surface of the display, this phenomenon hardly occurs for panels with S-IPS technology. Further, liquid crystals return to starting position after touch 10 times faster than panels with VA technology. |
