    • A display driver circuit for driving a flat panel display including circuitry for detecting integrity of bonding of outputs of the driver circuit to the display. The bond integrity detecting circuitry includes a test mode current source which applies current to the output being tested to raise its voltage to a threshold level. At a defined sampling time following initiation of application of the test mode current, the voltage on the output being tested is compared to the threshold level, and the result of the comparison is stored and output from the driver circuit. If the voltage of the output has not reached the threshold level at the defined sampling time, the output connection is determined to be good.
    • 一种用于驱动平板显示器的显示驱动器电路,包括用于检测驱动器电路的输出到显示器的结合的完整性的电路。 键合完整性检测电路包括测试模式电流源,其将电流施加到被测试的输出以将其电压升高到阈值水平。 在开始施加测试模式电流之后的定义的采样时间,将被测试的输出上的电压与阈值电平进行比较,并将比较结果存储并从驱动器电路输出。 如果在定义的采样时间输出的电压没有达到阈值电平,则输出连接被确定为良好。

    • A column-driver integrated circuit, and related method, for driving the columns of LCD displays uses paired digital-to-analog converters to provide analog signals in an upper voltage range and in a lower voltage range. During a first drive cycle, first and second digital data words are provided to the first and second digital-to-analog converters; the first and second digital data words represent the magnitudes, within the upper voltage range and lower voltage range, respectively, of the analog signals to be driven onto first and second columns of the LCD display. The analog signal generated by the first D/A converter is selected, as by a multiplexer, onto the first column of the display, and the analog signal generated by the second D/A converter is selected onto the second column of the display. During a second subsequent drive cycle, first and second digital data words are again provided to the first and second D/A converters, but now the first and second digital data word represent the magnitudes, within the upper voltage range and lower voltage range, respectively, of the analog signals to be driven onto the second and first columns, respectively, of the LCD display. The analog signal generated by the first D/A converter during the second drive cycle is selected onto the second column of the display, and the analog signal generated by the second D/A converter is selected onto the first column of the display.
    • 用于驱动LCD显示器列的列驱动器集成电路和相关方法使用成对的数模转换器来提供在较高电压范围和较低电压范围内的模拟信号。 在第一驱动周期期间,将第一和第二数字数据字提供给第一和第二数模转换器; 第一和第二数字数据字分别表示要驱动到LCD显示器的第一和第二列上的模拟信号的上限电压范围和较低电压范围内的幅度。 由第一D / A转换器产生的模拟信号通过多路复用器被选择在​​显示器的第一列上,并且由第二D / A转换器产生的模拟信号被选择到显示器的第二列上。 在第二个随后的驱动周期期间,第一和第二数字数据字再次提供给第一和第二D / A转换器,但是现在第一和第二数字数据字分别表示在上限电压范围和较低电压范围内的幅度 ,分别驱动到LCD显示器的第二列和第一列上的模拟信号。 在第二驱动周期期间由第一D / A转换器产生的模拟信号被选择在显示器的第二列上,并且由第二D / A转换器产生的模拟信号被选择到显示器的第一列。
