Precaution for creating App for BT-300

This product uses a Si-OLED (Organic EL Pane) for display panel. Due to the general characteristic of the Si-OLED, you may notice burn-in or decreasing luminance on the panel. To reduce the burn-in, please note the following points to create Apps.

  • Have screen transition that the same screen does not display for long time
  • Avoid using high brightness color scheme for character display, marker display and object display that always display at same position
  • Countermeasure using sleep function or implementing screen saver process into the App to avoid no operation state for long time

1.3. Functions of SDK

By using the Epson original APIs as well as the standard Android APIs (API level 22), the BT-300 can use specific functions that are not built-in to the standard Android system.

Table 1-2 Table of each function and which API to use
