The present invention relates to a liquid crystal display device, and more particularly, to a gate-in-panel (GIP) type dual gate structure liquid crystal display device for minimizing a region occupied by a gate driving unit in the GIP structure liquid crystal display device in which the gate driving unit supplying a gate driving signal is formed on a liquid crystal panel to implement a narrow-bezel, and improving image quality deterioration due to signal delay. According to the present invention, the number of stages may be reduced through the structure of alternately outputting a gate driving voltage other than the structure of simultaneously outputting a gate driving voltage from two gate driving units in a dual GIP type liquid crystal display, thereby minimizing an area occupied by the gate driving unit.

There is provided an ink jet printing apparatus in which unevenness that may occur at the edges of printing areas can be reduced also for various printing media including unspecified printing media. In the ink jet printing apparatus which uses a print head for ejecting ink and performs printing by scanning a predetermined area on a printing medium with the print head multiple times, the multiple times of scan including a forward scan and a backward scan, the apparatus comprising: a control unit that cases the print head to print patterns each of which is printed through multiple times of scan of the print head and has different portions in a time interval between the multiple times of scan, with different printing ratios for the multiple times of scan; and a setting unit that sets the printing ratios based on the test patterns.

A recording apparatus of the present invention includes a temperature detector which detects a temperature of a pulse generator, and a driver which drives the pulse generator. When the temperature detector detects a temperature equal to or higher than a predetermined maximum temperature, a stopper stops a driver after driving of the pulse generator corresponding to one or a plurality of driving units is completed. A temperature estimator estimates an increased temperature of the pulse generator based on a pulse pattern which will be generated by the pulse generator thus driven again. A restarter makes the driver restart driving the pulse generator when, after the driver is stopped, a temperature detected by the temperature detector drops to a restart temperature which is equal to or lower than a temperature value obtained by subtracting the increased temperature from the maximum temperature.

A semiconductor device includes a photoelectric conversion element outputting an electric signal in accordance with an externally input optical signal, an internal circuit processing the electric signal, a signal terminal inputting or outputting a signal to the internal circuit, a first voltage terminal supplying a first voltage to the internal circuit, and a second voltage terminal supplying a second voltage lower than the first voltage to the internal circuit. The semiconductor device further includes a first protection element connected in an electrically reverse direction between the signal terminal and the first voltage and having at least one PN junction and a second protection element connected in an electrically reverse direction between the first voltage and the second voltage and having at least one PN junction, so that immunity to electrostatic noise can be improved and electrostatic breakdown and malfunction of the photoelectric conversion element can be suppressed.

An ultraviolet-curable liquid developer containing a cationically polymerizable liquid monomer, a photoinitiator, and a toner particle, wherein the cationically polymerizable liquid monomer contains a vinyl ether compound, the molar average SP value of the cationically polymerizable liquid monomer is not more than 9.0, the molar average number of functional groups for the cationically polymerizable liquid monomer is at least 1.8, the photoinitiator contains a specified compound, and the content of the specified compound is at least 0.01 mass parts and not more than 5.00 mass parts per 100 mass parts of the cationically polymerizable liquid monomer.

A discharge unit is disposed downstream of a principal transport path of a compound machine, and a shifter function is provided in this discharge unit. By shifting the paper passage position relative to a photosensitive drum when printing the front side and the paper passage position relative to the photosensitive drum when printing the back side, the region in which the surface electric potential of the photosensitive drum increases is diminished, and the region in which photographic fog is generated is made smaller. Thus, when printing the second and subsequent sheets, even when a slight amount of displacement of the transport position of the recording paper occurs, it is possible to suppress that recording paper making contact in the photographic fog region on the photosensitive drum, and defective printing can be prevented.

A display apparatus capable of correcting an image quality change caused by long-term use is provided. The display apparatus includes: a display panel; a communicator configured to communicate with a service apparatus; and a controller configured to control the communicator to transmit operation information including a total operating time of the display apparatus and an operating temperature of the display apparatus, to the service apparatus; receive an image parameter from the service apparatus through the communicator, and based on the received image parameter data; process image data; and transmit the processed image to the display panel. The image parameter may include at least one of a brightness level, a contrast, a sharpness level, and a color density of the display panel.
