1.3 LCD panel Specification Technical Specification Item LCD panel Specification Unit Panel Model M190E5-L0A LCD panel Active Area 376.32 (H) x 301.056 (V) (19.0” diagonal) Driver Element a-si TFT Active Matrix Pixel Number 1280 x R.G.B. x 1024 Pixel Pitch 0.294 (H) x 0.294 (V) Pixel Arrangement RGB Vertical Stripe Display Color 16.
(1) Definition of Viewing Angle (θx, θy): Normal θx = θy = 0º θyθX- = 90º θy+ x- y+ θx- 6 o’clock θy- = 90º 12 o’clock direction θy+ = 90º θx+ Y- x+ 10 θX+ = 90º
Definition of Contrast Ratio (CR): The contrast ratio can be calculated by the following expression and figure below. Contrast Ratio (CR) = L255 / L0 L255: Luminance of gray level 255 L 0: Luminance of gray level 0 CR = CR (5) CR (X) is corresponding to the Contrast Ratio of the point X at Figure in Note (5). Definition of luminance measured points and Brightness Uniformity: Horizontal Line Number [pixel] Vertical Line Number [pixel] (2) X : Test point Active area Delta X=17.0mm;Delta Y=17.
(3) Definition of Response Time (TR , TF ) and Measurement Method: Gray Level 255 Gray Level 255 100% 90% Optical Response Gray Level 0 10% 0% Time TF TR (4) Luminance, Chromaticity and CCT Measurement Measurement System Setup: The LCD module should be stabilized at given temperature for 15 minutes to avoid abrupt temperature change during measuring. In order to stabilize the luminance, the measurement should be executed after lighting Backlight for 15 minutes in a windless room.
