In color GLCDs, each individual pixel is divided into three cells, or subpixels, which are colored red (R<\/span>), green (G<\/span>), and blue (B<\/span>).<\/p>\n

In GLCDs, the most important thing in interfacing color GLCD is to know how color is defined to a given pixel. Available formats depends on the brand and type of GLCD controller built in the choosen module :<\/p>\n

12 bit per pixel pixel format (12bpp)
\nRRRR<\/span>GGGG<\/span><\/strong>\u00a0 4 bits red and 4 bits green 1st\u00a0pixel BBBB<\/span>RRRR<\/span>\u00a0\u00a0<\/strong> 4 bits blue 1st pixel and 4 bits red 2nd\u00a0\u00a0pixel GGGG<\/span>BBBB\u00a0 4 bits\u00a0 green and 4 bits blue 2nd pixel<\/p>\n

8 bit per pixel pixel format (8bpp)
\nRRR<\/span>GGG<\/span>BB<\/span><\/strong>\u00a0 3 bits red, 3 bits green and 2 bits blue<\/p>\n

16 bit per pixel pixel format (16bpp)
\nRRRRR<\/span>GGG<\/span><\/strong>\u00a0 5 bits red and 3 bits green 1st pixel GGG<\/span>BBBBB<\/span><\/strong>\u00a0 3 bits red and 5 bits blue 1st pixel<\/p>\n

The Bitmap2LCD programming tool\u00a0supports these GLCD color formats from V2.0.<\/p>\n\t
