A display device includes detection sections each of which is arranged in an associated one of a plurality of pixels, and is configured to detect a pressed position; scan lines and detection lines formed on a first substrate; and a detection driver connected to the detection lines. When the first substrate or a second substrate is pressed, and the detection section in the pressed area is scanned with the scan line, the detection driver detects a voltage applied to the detection section via the detection line. An inspection line to which at least the scan lines or the detection lines are connected in parallel is further formed on the first substrate.

In one embodiment of the present application, a memory stores a lookup table storing, in accordance with a combination of a value of a video signal of a current frame and a value of a video signal of a previous frame, each of correction values, the correction values in each of which a temporal change of a video signal is enhanced. A correcting circuit carries out, with respect to a correction value selected from the lookup table, a predetermined correcting operation in accordance with a polarity of a voltage to be applied to each of data signal lines S1 through Sm, with the use of a correction coefficient which is set based on properties of liquid crystal. Thus found is a corrected video signal in accordance with a positive or negative polarity. This makes it possible to find, with less memory capacity, an optimum corrected video signal in accordance with a polarity of a voltage to be applied to a data signal line.

The present invention provides a highly accurate oscillation circuit. For example, the oscillation circuit includes plural ring oscillator units RO1 and RO2 including inverter circuits IV of an odd number of stages, and an adding unit ADD that adds signals of output nodes RO—01 and RO—02 of the RO1 and RO2. It outputs an addition result of the ADD from an output node OSC_O as a clock signal, and feeds the output node OSC_O back to input nodes RO_I1 and RO_I2 of the RO1 and RO2. Thereby, for example, when each of delay times of the RO1 and RO2 disperses based on a normal distribution of standard deviation σ, the dispersion of a clock signal obtained from the OSC_O can be confined to σ/√{square root over (2)}.

A method, apparatus, and computer program instructions for automatically performing test builds of natural language translated files for a software product. When a translated file is received from a translator, a test build of the translated file is executed in a translation test build environment, wherein the translation test build environment is separate from the main software product build environment. A determination is made as to whether the test build of the translated file is successful. If the test build is successful, the translated file is submitted to the main software product build environment. If the test build is unsuccessful, a log file containing error information is sent to the translator to allow the translator to fix compile errors identified in the translated file and resubmit the translated file to the translation test build environment.
