The fixed line function is used to implement the partial scroll function by dividing the screen into scroll and
fixed area. Set Fixed Lines command will define the fixed area, which will not be affected by the SL scroll
function. The fixed area covers the top 2xFL rows for mirror Y (MY) is 0 and bottom 2xFL rows for MY=1.
One example of the visual effect on LCD is illustrated in the figure below.
When partial display mode is activated, the display of these 2xFL lines is also controlled by LC[0]. ]. Before
turning on LC[0], please make sure
(15) S
Program LC [4:3] for line rate setting (Frame-Rate = Line-Rate / Mux-Rate). The line rate is automatically
scaled down by 1/2 and 1/3 at Mux-Rate = 38 and 24.
The following are line rates at Mux Rate = 39 ~ 80.
(16) S
Set DC[1] to force all SEG drivers to output ON signals. This function has no effect on the existing data
stored in display RAM.
(17) S
Set DC[0] to force all SEG drivers to output the inverse of the data (bit-wise) stored in display RAM. This
function has no effect on the existing data stored in display RAM.
