The signal is used to perform the image test on the tested LC Μ 8 3. However, the existing standard signal format 8 3 of the built-in LC LM signal generator 8 2 is limited to the large-scale LC Μ, and it does not support 8 ◦ / 6 8. The mobile industry processor interface (ΜPI) data transmission and RG Β interface (Interface) data transmission are not applicable to small and medium-sized LC LCs. Because the color medium and small size LC MU has a variety of module models, and the input signal, control register, and address area of the drive IC (D ri ν er IC) of different vendors or models of LC MU are different, The required driver must be loaded in the LC Μ signal generator 8 2 before testing.
