摘要： An object of the present invention is to realize the gray shading through PWM in the MLS drive method while minimizing increase of the number of voltage levels and degradation of the display characteristics. A given calculation is performed out by using a gray shades data, a virtual data generated by the gray shades data and an orthogonal function. The resulting data is then used to perform the pulse width modulation to realize the pulse width modulation of binary level in the MLS drive method. The virtual data is generated so that the sum of the number of 1 in the gray shades data and the number of 1 in the virtual data is even number. The gray shades data and virtual data are converted into data symmetrical about 0. The converted data is used with an orthogonal function to perform a matrix calculation with the result thereof being then converted into a positive integer. Alternatively, the gray shades data, virtual data and orthogonal function are used to perform a matrix calculation. An addition is performed based on the result of the matrix calculation together with a constant corresponding to the sum of row elements in the orthogonal function. A display controller may generate PWM data or a segment driver including a memory may generate PWM data.

摘要： In a period T1 (positive polarity) in which a voltage level of a counter electrode VCOM becomes VC1, a data line is driven using P-type operational amplifier OP1 having P-type driving transistor, while in a period T2 (negative polarity) in which VCOM becomes VC2, the data line is driven using N-type operational amplifier OP2 having N-type driving transistor. An output of a selection circuit for the operational amplifiers OP1, OP2 is set to the high impedance state when VCOM is changed over. At the time of driving the operational amplifier OP1, a current which flows in current sources of the operational amplifier OP2 is cut off, while at the time of driving the operational amplifier OP2, a current which flows in current sources of the operational amplifier OP1 is cut off. In the period before the operational amplifiers OP1, OP2 are driven, the driving transistors of the operational amplifiers OP1, OP2 are turned off. The voltage level of the data line can be changed before driving by positively utilizing the parasitic capacitance between the counter electrode and data line.

摘要： A display driver, a display unit, and an electronic instrument that enables the simultaneous display of a still image and a moving image on the same scan line. An X driver IC includes at least display data RAM, in which is stored still-image data for one frame, and a line memory, in which is stored moving-image data for one scan line. A selector circuit selects one of still-image data for one scan line in the horizontal direction, which is read from the display data RAM, or moving-image data for one scan line, which is read from the line memory, based on image determination data, and outputs it as composite data of a still image and a moving image, for each column position. After the composite data has been latched by an output latch circuit, a liquid crystal panel is driven based on the latched data by a liquid crystal drive circuit.

摘要： An output of an operational amplifier circuit is set to the high impedance state in a given period including a transition between a period T1 (positive polarity) in which a voltage level of a counter electrode VCOM becomes VC1 and a period T2 (negative polarity) in which VCOM becomes VC2. In the period T1, data line is driven by a P-type operational amplifier OP1 having a P-type driving transistor, while in the period T2, the data line is driven by an N-type operational amplifier OP2 having an N-type driving transistor. By positively using a parasitic capacitance between the counter electrode and the data line, the voltage level of the data line is changed before driving. The excess charge is returned to the power source side by clamping the output of the operational amplifier circuit to a voltage range equal to or wider than a voltage range of power sources VDD and VSS. The voltage range of power sources VDD′ and VSS′ of a clamp circuit are set to be narrower than that of the power sources VDD and VSS of the operational amplifier circuit.

摘要： A liquid crystal display panel is driven by scan line inversion driving. Here, a virtual scanning period is provided between an Mth scanning period and a first scanning period which constitutes a frame next to the Mth scanning period. In the virtual period, the display panel is driven by setting a voltage level of a counter electrode VCOM to a voltage level different from VCOM during the Mth and the first scanning periods. During the period T1 in which VCOM becomes VC1, data line is driven using a P-type operational amplifier OP1 having a P-type driving transistor, while during the period T2 in which VCOM becomes VC2, the data line is driven using an N-type operational amplifier OP2 having an N-type driving transistor. The data line is set to the high impedance state when the periods T1, T2 are changed over and the voltage level of the data line is preliminarily changed to the VDD side or the VSS side before driving by positively utilizing the parasitic capacitance between the counter electrode and the data line.
