§ ‘Transflective’ Displays
A reflective LCD relies on ambient light to read out displayed informations. When the ambient light is dim, the display isn’t readable whether built-in light is available or not.
We must develop a trans-flective display to overcome such a problem.
In a trans-flective LCD, each pixel is split into reflective sub-pixels ( R ) and transmissive sub-pixels ( T ). Usually, the R & T area ratio is 4 : 1 in favor of reflection.
The backlight is used for dark ambient only for conserving power.
