Buffer amplifier included in display driver and method of generating driving voltages using the same |
摘要 |
A method of generating a driving voltage includes inputting a test gradation voltage to a first input terminal and a second input terminal of a buffer, latching the logic level of a test driving voltage output from an output terminal of the buffer, setting the buffer to a first type when the logic level of the test driving voltage is high level and setting the buffer to a second type when the logic level of the test driving voltage is low level, and operating the buffer set to the first type or the second type to generate a driving voltage corresponding to a gradation voltage.
