Function Specifications 4.1 Power Circuit Example For providing bias voltage to the LCD module, an external bias circuit should be set up as follow. Note, adjusting the VLCD value will result the change of the LCD display contrast. C1 = 1.0uF ~ 4.7uF (25V or above) R1 = 4.7k (1/8W) R2 = 39k (1/8W) R3 = 4R7 (1/8W) U1 = LM324 (or equivalent) 4.2 Display Pixel Map 1,1 (D3) 2,1 (D2) 3,1 (D1) 4,1 (D0) 5,1 (D3) - - - - - - 316,1 (D0) 317,1 (D3) 318,1 (D2) 319,1 (D1) 320,1 (D0) 1,2 (D3) 2,2 (D2) 3,2 (D1) 4,2 (D0) 5,2 (D3) - - - - - - 316,2 (D0) 317,2 (D3) 318,2 (D2) 319,2 (D1) 320,2 (D0) 1,3 (D3) 2,3 (D2) 3,3 (D1) 4,3 (D0) 5,3 (D3) - - - - - - 316,3 (D0) 317,3 (D3) 318,3 (D2) 319,3 (D1) 320,3 (D0) : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : 1,238 (D3) 2,238 (D2) 3,238 (D1) 4,238 (D0) 5,238 (D3) - - - - - - 316,238 (D0) 317,238 (D3) 318,238 (D2) 319,238 (D1) 320,238 (D0) 1,239 (D3) 2,239 (D2) 3,239 (D1) 4,239 (D0) 5,239 (D3) - - - - - - 316,239 (D0) 317,239 (D3) 318,239 (D2) 319,239 (D1) 320,239 (D0) 1,240 (D3) 2,240 (D2) 3,240 (D1) 4,240 (D0) 5,240 (D3) - - - - - - 316,240 (D0) 317,240 (D3) 318,240 (D2) 319,240 (D1) 320,240 (D0) Pixel mapping (Top View) Based on the top view of the LCD module, the 1, 1 (x, y) pixel is the upper-left pixel; the 320, 240 (x, y) pixel is the lower-right pixel. |
