Make full screen logo :

• I suggest you first create your logo in the actual size of your screen in Paint or Photoshop. If this size is too small to view, you can make it at X rate of screen size. For example, if your LCD/OLED screen size is 128 dots by 64 dots, you can create 10x with a size of 1280 x 640. Then it is better to save it with the lowest(8 or 16) bit and in .BMP or .JPG format and use it in OLEDH software.
• Change with and height in the software to your lcd/oled resolution .

• Click on Load Image button and select your logo image file.
• Do not worry if the photo turns black after loading. You have two very valuable contrast and brightness settings that help you create the right logo in a single color from this image. Adjust the contrast first and then the brightness. You will often have to adjust the brightness.

• your new logo is ready now. please click on Image to HEX button. the binary and hex will generate in their tabs
