摘要： To simplify a manufacturing process of a transverse electric field mode liquid crystal display device by using a non-linear resistance element such as a TFD (Thin Film Diode) as a switching element. In a liquid crystal display device having a pair of substrates with liquid crystal interposed therebetween, one of the substrates consists of an electrode substrate. On the electrode substrate, there are provided a first group of electrodes, a second group of electrodes crossing the first group of electrodes with an insulating layer interposed therebetween, non-linear resistance elements, one end of each of the non-linear resistance elements being connected to the respective one of the second group of electrodes, and pixel electrodes opposing the first group of electrodes, each pixel electrode being connected to the other end of each of the non-linear resistance elements. Since the non-linear resistance elements have a so-called TFD (MIM) structure made of metal-insulating layer-metal, the manufacturing process is simple. Therefore, it is possible to manufacture the transverse electric field mode display device at low cost.

摘要： An ON/OFF control signal 105 directive of turning ON in a transmissive display mode or turning OFF in a reflective display mode is output by an ON/OFF state controlling means 111 to a light source 115. The ON/OFF control signal 105 is also output to a data signal converting means 104, and the data signal converting means 104 converts a data signal 102 into a data signal 103 in synchronization with the switching of ON and OFF of the light source 115 so as to prevent positive-negative inversion of the display on a liquid crystal panel 114. A data signal potential supplying means 112 supplies a potential of a data signal based on the data signal 103 to a data signal line 113 so as to drive the liquid crystal panel 114.

摘要： An ejection head driving circuit that supplies a driving voltage waveform to an ejection head has ejection nozzles that cause fluid to be ejected. A target voltage waveform output unit outputs a target voltage waveform to the ejection head. Power source units generate electric power at different voltage values. Negative feedback control units supply electric power from the respective power source units to the ejection head and perform a negative feedback control of the voltage values so that the voltage value to be applied to the ejection head matches the target voltage waveform. A power source connecting unit selects one of the power source units on the basis of the voltage value applied to the ejection head or the voltage value of the target voltage waveform, connects the selected power source unit to the ejection head, and disconnects the remaining power source units from the ejection head.

摘要： The invention prevents display tearing involved with refreshing of a display memory when grayscale data corresponding to a pixel is read from the display memory and is displayed on a display panel. If a refresh has occurred during a reading and scanning operation of a display memory, a display controller skips the reading operation of the grayscale data corresponding to rows subsequent to the row which was being read and scanned when the refresh occurred. The content from a frame immediately before the frame in which the refresh occurred is maintained in the skipped pixel.
