    • A display device and mobile terminal are provided. The display device can narrow the pitch, able to narrower the frame, and able to further reduce power consumption, comprising a display area; a vertical drive circuit; a first horizontal drive circuit converting input first and second digital image data to analog image signals, and supplying the same to a data line selected by the vertical drive circuit; and a second horizontal drive circuit converting input third digital image data to an analog image signal, and supplying the same to a data line selected by the vertical drive circuit, wherein the first horizontal drive circuit includes a sampling latch circuit for sequentially sampling and latching the first and second digital image data, a second latch circuit for latching the latch data of the sampling latch circuit again, a digital/analog conversion circuit (DAC) for converting the digital image data latched by the second latch circuit to an analog image signal, and a line selector for selecting the first and second digital image data converted to analog data by the DAC in a time division manner in a predetermined period and outputting the same to the data line.
    • 提供了显示装置和移动终端。 显示装置可以缩小音调,能够缩小框架,并且能够进一步降低功耗,包括显示区域; 垂直驱动电路; 第一水平驱动电路,将输入的第一和第二数字图像数据转换为模拟图像信号,并将其提供给由垂直驱动电路选择的数据线; 以及第二水平驱动电路,将输入的第三数字图像数据转换为模拟图像信号,并将其提供给由垂直驱动电路选择的数据线,其中第一水平驱动电路包括采样锁存电路,用于顺序采样和锁存 第一和第二数字图像数据,用于再次锁存采样锁存电路的锁存数据的第二锁存电路,用于将由第二锁存电路锁存的数字图像数据转换为模拟图像信号的数/模转换电路(DAC) 以及线选择器,用于在预定时间段内以时分方式选择由DAC转换为模拟数据的第一和第二数字图像数据,并将其输出到数据线。
