Abstract

See full text

A serial driving device for driving a passive module according to a number of digital pixel data is provided. The serial driving device includes a digital-to-analog converting unit, an analog buffer, a shift register, and an output buffer unit. The digital-to-analog converting unit is used for outputting a number of analog pixel data in series according to the digital pixel data. The pixel data output from the digital-to-analog converting unit is then processed by the analog buffer, the shift register, and the output buffer. The output buffer unit includes a number of driving sub-units for receiving the analog pixel data from the analog buffer in parallel. Each driving sub-units includes an output buffer, a primary switch, and a secondary switch. The primary switch is first turned on to drive the output terminal of the driving sub-unit toward an output voltage corresponding to the analog pixel data received by the driving sub-unit, and if the analog pixel data received by the driving sub-units are corresponding to the same gray level, the secondary switch is then turned on to drive the output terminal of the driving sub-units toward an average voltage.
