b154ew04 v.b page /23 4 1. application this specification applies to a color tft-lcd module, b154ew04 vb(qd15tl0702). 2. overview this module is a color active matrix lcd module incorporating amorphous silicon tft (thin film transistor). it is composed of a color tft-lcd panel; driver ics, control circuit and power supply circuit and a backlight unit. graphics and texts can be displayed on a 1280 3 800 dots panel with 262,144 colors by using lvds (l ow v oltage d ifferential s ignaling) to interface and supplying +3.3v dc supply voltage for tft-lcd panel driving and supply voltage for backlight. the tft-lcd panel used for this module has very high aperture ratio. a low-reflection and higher-color-saturation type color filter is also used for this panel. therefore, high-brightness and high-contrast image, which is suitable for the multimedia use, can be obtained by using this module. optimum viewing direction is 6 o'clock. [features] 1) high aperture panel; high-brightness or low power consumption. 2) brilliant and high contrast image. 3) small footprint and thin shape. 4) light weight. 5) wide screen 15.4 wxga 6) rohs compliant 3. general specifications parameter specifications unit display size 390.1 (15.4 ) diagonal mm active area 331.2 207.0 mm pixel format 1280 (h) 800 (v) pixel (1 pixel = r+g+b dots) pixel pitch 0.2588(h) 0.2588 (v) mm pixel configuration r, g, b vertical stripe display mode normally white unit outline dimensions (typ.)*1 344.0(w) 222.0 (h) 6.35(t)max. mm mass 585 max. g surface treatment glare + hard coating 3h *1.note: excluding backlight cables. outline dimensions are shown in this specification. pdf created with fineprint pdffactory pro trial version www.pdffactory.com www..net

(note) the performance of the backlight, for example life time or brightness, is much influenced by the characteristics of the dc-ac inverter for the lamp. when you design or order the inverter, please make sure that a poor lighting caused by the mismatch of the backlight and the inverter (miss-lighting, flicker, etc.) never occur. when you confirm it, the module should be operated in the same condition as it is installed in your instrument. module 1 2 inverter a pdf created with fineprint pdffactory pro trial version www.pdffactory.com www..net
