    • An object of the invention of the present application is to drive data signal lines accurately by pulse width modulation driving and display gradations accurately. A PWM pattern generating circuit (12) generates 2q sets of PWM patterns associated with combinations of a gradation and the polarity of a gradation voltage. A selector (15) selects one PWM pattern from among the 2p+q PWM patterns, based on gradation data and a pattern set number. A charge and discharge control circuit (16) controls a charge and discharge circuit (17) to apply a charge voltage and a discharge voltage to a data signal line in a switching manner, based on the selected PWM pattern. One correction pulse may be selected for each data signal line from among a plurality of types of generated correction pulses, and a charge voltage may be applied to the data signal line based on the correction pulse. A plurality of charging transistors may be provided, and a charging transistor to be used may be specified for each data signal line, according to the temperature.
    • 本发明的目的是通过脉宽调制驱动和显示灰度准确地驱动数据信号线。 PWM模式发生电路(12)产生与灰度级和灰度电压的极性相关联的2q组PWM模式。 选择器(15)基于灰度数据和图案集编号从2p + q个PWM模式中选择一个PWM模式。 充放电控制电路(16)基于选择的PWM模式控制充放电电路(17)以切换方式向数据信号线施加充电电压和放电电压。 可以从多种类型的所生成的校正脉冲中的每个数据信号线选择一个校正脉冲,并且可以基于校正脉冲将充电电压施加到数据信号线。 可以提供多个充电晶体管,并且可以根据温度为每个数据信号线指定要使用的充电晶体管。

    • The sub panel 100, having a plurality of gate bus lines 14, source bus lines 16, TFTs 25 and pixel electrodes, is provided with a source driver 15. The main panel 200 has a plurality of gate bus lines 24, source bus lines 16, TFTs 25 and pixel electrodes, each of the source bus lines 16 being connected to the corresponding source bus lines 16 of the first liquid crystal panel 10 through a switching TFT 17. The main panel 200, sharing the source driver 15 with the first liquid crystal panel 10, is less frequently used for display than the first liquid crystal panel 10, and is disconnected by the switching TFT 17 when only the sub panel 100 is used. This makes it possible to device a twin-panel display device low in electric power consumption.
    • 具有多个栅极总线14,源极总线16,TFT25和像素电极的子面板100设置有源极驱动器15.主面板200具有多个栅极总线24,源极总线16 ,TFT25和像素电极,每个源极总线16通过开关TFT 17连接到第一液晶面板10的对应的源极总线16.主面板200将源极驱动器15与第一液体 晶体面板10比第一液晶面板10更不频繁地用于显示,并且仅在使用子面板100时由开关TFT 17断开。 这使得可以设置低功耗的双面显示装置。
