Sanyo 42LM4WPTC, 42LM5RTC, 42LM4RTC Using Edge Enhancement, Delayed Starting Of The Driver Output

USING EDGE ENHANCEMENT

1.To allow easy access to the sliders and buttons at the edge of the display, the cursor can be positioned nearer the edge of the screen. The amount of enhancement can be adjusted via the screen shown.

Fig 13

2.Each of the sliders represents one edge of the sensor; the default position is as illustrated above (Fig 13).

3.Edge Gain can also be used to counteract the effects of nearby metalwork that surrounds the display area.

4.The further the sliders are away from the centre, the greater enhancement is given to the appropriate edge.

Too much edge enhancement will force the cursor to the edge of the display where it may not have the desired effect.

DELAYED STARTING OF THE DRIVER OUTPUT

1.When starting a touchscreen computer system, it is sometime desirable to be able to prevent users from interfering with the start-up procedures from the touchscreen. Delaying the action from the touchscreen driver to the application can do this.

2.This can be done by editing the MA7.ini file. This is found in the same directory as the MA7_Control_En and MA7_Driver_En programs. There is a line, StartDelayInt1=0. By changing the 0 to a number between 1 and 120 adds a delay of up to 120 seconds between the time when the driver is loaded and when it can be used to control an application program.
