RAM Address and Display Position on the Panel

The R61509V has memory to store display data of 240RGB x 432 lines. The R61509V incorporates a circuit to control partial display, which allows switching driving method between full-screen display mode and partial display mode.

The R61509V makes display arrangement setting and panel driving position control setting separately and specifies RAM area for each image displayed on the panel.

The following is the sequence of setting full-screen and partial display.

1.Set (PTSA, PTEA) to specify the RAM area for each partial image

2.Set the display position of each partial image on the base image by setting PTDP.

3.Set NL to specify the number of lines to drive the liquid crystal panel to display the base image

4.After display ON, set display enable bits (BASEE, PTDE) to display respective images

Normal display

BASEE = 1, PTDE = 0

Partial display

BASEE = 0, PTDE = 1

5.Changes BASEE, PTDE settings when turning on and off the full and partial displays 1/2.

In driving the liquid crystal panel, the clock signal for gate line scan is supplied consecutively via interface in accordance with the number of lines to drive the liquid crystal panel (NL setting).

When switching the display position in horizontal direction, set SS bit when writing RAM data.
