Abstract

The invention discloses a source electrode driven integrated circuit framework of display, comprising a shift cache for temporarily storing a data signal, a linear buffer coupled to the shift cache and used for latching the data signal, a standard potential shifter coupled to the linear buffer and used for lifting output electric potential, a digital analogue converter for converting data and analogue signal, an output buffer coupled to the digital analogue converter and outputting the converted data, and an output control circuit coupled to the output buffer. The output control circuit comprises a positive edge trigger flip-flop and a complementary metal-oxide semiconductor switch component, and can output an LP output signal to control the data signal output of the source electrode driven integrated circuit, so as to avoid the noise generated in the process of turning on a display.

Description

technical field [0001] The invention relates to an output control circuit and method for a source drive of a flat panel display, especially a source drive integrated circuit architecture capable of eliminating startup noise of a flat panel display. Background technique [0002] In recent years, due to the breakthrough progress and vigorous development of image display technology, the traditional cathode ray display (CRT, cathode ray tube) has been mostly replaced by the so-called panel display (panel displayer), which is attributed to the panel The display has the advantages of small size, thin thickness, light weight, low power consumption, and low radiation, so it can become the mainstream of today's video display. Currently, a common panel display is a thin-film transistor liquid crystal display (TFT-LCD, thin-film transistor liquid crystal display). In addition, panel displays using light emitting diode (LED, Light Emitting Diode) components or plasma (plasma) principle...
