LM220WE4-SLA1 (Alias: LM220WE4 (SL)(A1)) is a 22.0 inch diagonal a-Si TFT-LCD display screen product from LG Display, with a built-in CCFL backlight, without backlight driver, without touch screen. On the basis of latest version datasheet Ver1.0 which was released out on 3 24 2009, LM220WE4-SLA1 supports display 1680(RGB)×1050 (WSXGA+) with aspect ratio of 16:10 (W:H), whose pixels are arranged in RGB Vertical Stripe. As for mechanical detail, it features active area of 473.76(W)×296.1(H) mm, outline size of 487.7(W)×320.1(H) mm, viewing area size of 477.7(W)×300.1(H) mm, with surface treament of Antiglare, Hard coating (3H), net weight of 2.37/2.49Kgs (Typ./Max.). As a IPS, Normally Black, Transmissive LCM product, LM220WE4-SLA1 can provides 300 cd/m² display brightness 1000:1 transimissive contrast ratio, 89/89/89/89 (Typ.)(CR≥10) (L/R/U/D) viewing angle, best view direction on Symmetry , and response time of 5.5/6.5 (Typ.)(Tr/Td); 5 (Typ.)(G to G) ms. Gray scale or the brightness of the sub-pixel is determined with a 8-bit gray scale signal for each dot, thus presenting a palette of 16.7M colors. This product adopted 6 pcs CCFL as it’s backlight systerm which was placed as Direct light type and have a working life time of 40K hours, external backlight driver is additionally needed. LM220WE4-SLA1 utilizes LVDS (2 ch, 8-bit) as it’s signal inputting systerm, which connected by 30 pins Connector with power supply voltage of 5.0V (Typ.). It’s typical vertical frame rate (Fv) is 60Hz.
