  • Patent number: 7319453
    Abstract: In a partial display mode, a source IC outputs a start signal at an “H” level designating the start of vertical scanning by a vertical scanning circuit, over a plurality of cycles from before a time T1 to after a time T8. A plurality of shift registers sequentially shift the start signal in synchronization with a clock signal to sequentially drive a plurality of activation enable signals, respectively, to an “H” level. Then, after time T8 when first to fourth activation enable signals simultaneously attain an “H” level, the source IC outputs an enabling signal at an “H” level to the vertical scanning circuit. In response, the vertical scanning circuit simultaneously activates first to fourth gate lines corresponding to the first to the fourth activation enable signals, respectively.

  • Patent number: 6985340
    Abstract: A protection circuit described herein protects an LCD module from static electricity generated at a first positive power supply terminal in a process of manufacturing the LCD module. The protection circuit includes four diodes connected in series between a first node connected to the first positive power supply terminal and a second node receiving a reference potential, and a diode connected between the second and first nodes. When a first positive power supply voltage (10V) is applied to the first positive power supply terminal, the four diodes do not conduct. Therefore, a current consumption of the LCD module can accurately be measured.

  • Patent number: 6982568
    Abstract: An LCD module includes: an odd-numbered data terminal for applying an odd-numbered data signal to each odd-numbered set of data lines through a first N-type TFT and a demultiplexer at inspection; an even-numbered data terminal for applying an even-numbered data signal to each even-numbered set of data lines through a second N-type TFT and the demultiplexer at inspection; and a control terminal for applying a control signal to gates of the first and second N-type TFTs at inspection. It is therefore possible to reduce the number of terminals to be used at inspection, thereby achieving a inspection device at low cost.

  • Patent number: 6611468
    Abstract: In a non-volatile semiconductor memory device, a constant current circuit is arranged in parallel with an NMOS diode converting a detected current on the array cell side to a voltage, and a constant current circuit is arranged in parallel with an NMOS diode converting a detected current on the reference cell side to a voltage. Constant current circuits supply an offset current. Thus, a difference between two input voltages of a differential amplifier increases.
