摘要： A display driving integrated circuit includes: a tone display reference voltage generating circuit for generating 64 tone display reference voltages by resistive division on the basis of a predetermined reference voltage; D/A conversion circuits each for performing an analog conversion with respect to display data on the basis of the 64 tone display reference voltages; and 64 reference voltage wires provided in parallel, via which the 64 tone display reference voltages are supplied to the D/A conversion circuits, respectively. The 64 reference voltage wires are provided so that a potential difference corresponds to two tones or more between adjacent two reference voltage wires.

摘要： In a gradation display reference voltage generating circuit, first reference voltages (VH0 to VH63) produced by resistors for positive polarity (RH0 to RH64) of a first ladder circuit in a first reference voltage producing section (LDH) are output from reference voltage output terminals (T0 to T63), respectively, at the positive polarity drive, while second reference voltages (VL0 to VL63) produced by resistors for negative polarity (RL0 to RL64) of a second ladder circuit in a second reference voltage producing section (LDL) are output from the reference voltage outputs (T0 to T63), respectively, at the negative polarity drive. A resistance ratio of the resistors for positive polarity (RH0 to RH64) is different from a resistance ratio of the resistors for negative polarity (RL0 to RL64).
