    • A digital pixel driver that operates in response to an M-bit digital input value defining the apparent brightness of the pixel. The pixel driver generates a pixel drive signal having a duty cycle that sets the apparent brightness of the pixel. The pixel driver comprises a memory, a digital sequence generator and a comparator. The memory receives and stores an N-bit word that represents the digital input value. The digital sequence generator generates a digital sequence of P-bit digital values that defines the temporal duration of the pixel drive signal and includes a first P-bit word that represents at least part of the digital input value at a location temporally corresponding to the duty cycle of the pixel drive signal as defined by the at least part of the digital input value. The comparator is connected to receive the digital sequence from the digital sequence generator and a second P-bit word from the memory. The second P-bit word constitutes at least part of the N-bit word. The comparator includes an output that provides the pixel drive signal and that changes state in response to correspondence between the first P-bit word and the second P-bit word.
    • 数字像素驱动器,响应于定义像素的表观亮度的M位数字输入值而工作。 像素驱动器产生具有设置像素的表观亮度的占空比的像素驱动信号。 像素驱动器包括存储器,数字序列发生器和比较器。 存储器接收并存储表示数字输入值的N位字。 数字序列发生器产生定义像素驱动信号的时间持续时间的P位数字值的数字序列,并且包括在时间上对应于占空比的位置处表示数字输入值的至少一部分的第一P位字 由数字输入值的至少一部分定义的像素驱动信号的周期。 连接比较器以从数字序列发生器接收数字序列,并从存储器接收第二个P位字。 第二P位字构成N位字的至少一部分。 比较器包括提供像素驱动信号并且响应于第一P位字和第二P位字之间的对应关系而改变状态的输出。
