User Interface

NHL-2NA user interface appearance is described below in fig.1. It comprises LG4 module and assembly parts.

UI Module features

16-gray scale by PWM, 4096-color is available.
Backlight unit is provided, so the display can be used in both reflective mode and transmissive mode.
Direct data display by display data RAM (normally-white LCD)
RAM bit data "1111" . . . OFF (minimum voltage) Red, green, blue "0000" . . . ON (maximum voltage) Black (in the normal display mode)
Partial display function
power saving by pausing display process on part of the screen.
Built-in RAM capacity 4 x 648 x 240 = 622,080 bits.
•MPU interface.
Directly connectable to an 8-bit parallel MPU, both 80 and 68 series
A host of command functions (area scrolling, automatic page & column incre­menting, and power controlling functions).
Embedded oscillating circuit.
User interface keys are provided.

AC Characteristics of the Display
Signal timings are shown in Figure 7. Read/write characteristics and Table 10. AC charac­teristics. All the characteristics in this chapter are specified for the whole UI module, including the UI-FPC.
Notes: Rise and fall time must be within 20 ns. Timings of T
ACC8
and T
are according
OH8
to 20% and 80% VDDI-GND. Other timings are according to 30% and 70% of VDDI-GND. t
CCLW
and t
are specified according to overlapping of low level periods of CSX and
CCLR
WRX (RDX).
Definitions to rise and fall times as described in Figure 8. Rise and fall time in input and output and Rise and fall times in input and output of display driver.

Displayed Data
Pixel and dot ordering in parallel transfer from engine to display is shown in Figure 9. Pixel and dot order in transfer. Three bytes (RG, BR and BG) are needed to send data of two pixels, as data of one pixel is 12 bits. Corresponding order in panel is shown in Figure
10. Pixel data order in display panel.
