摘要:
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.

Correction data tables or look up tables (LUTs) are stored in a table memory. When an overshoot calculation section switches an active LUT, the overshoot calculation section obtains the new active LUT not out of an external memory but out of the table memory. A table managing section deletes, from the internal memory, LUTs to which the new active LUT does not switch over directly, for example non-adjacent LUTs, meanwhile the table managing section obtains a new adjacent LUT from the external memory so as to store the new adjacent LUT in the table memory. With the arrangement, it becomes possible for a drive circuit to (i) operate at the same processing speed as a drive circuit in which all tables are stored in the internal memory, and simultaneously, (ii) reduce the amount of memory.

In one embodiment of the present invention, LUTs (T3) through (T5) are stored in a table memory. When an overshoot calculation section switches over from the LUT (T4), which is being used, to the LUT (T5), the overshoot calculation section obtains the LUT (T5) not out of an external memory but out of the table memory. At this time, in order that the overshoot calculation section can switch over quickly from the LUT (T5) to an LUT (T6) at the next time, a table managing section deletes, from the internal memory, the LUT (T3) to which the LUT (T5) does not switch over directly, meanwhile the table managing section obtains the LUT from the external memory so as to store the LUT (T6) in the table memory. With the arrangement, it becomes possible for a drive circuit to (i) operate at the same processing speed as a drive circuit in which all tables are stored in the internal memory, and simultaneously, (ii) reduce the amount of memory.

The present inventors conducted dedicated studies and successfully constructed expression vectors that enable high-level production of foreign gene-derived proteins in mammalian host cells, which comprise a translation-impaired dihydrofolate reductase gene cistron whose expression has been attenuated by altering the codons to the least frequently used codons in mammals; and a gene cassette which has a cloning site for incorporation of a foreign gene between a highly transcriptionally active promoter and a highly stable polyadenylation signal.

A display system displays objects in a display region in a manner arranged in a predetermined orientation. One light-emitting element of a sensor array emits light to the objects in the predetermined orientation. The display system prestores data which associates numerical value ranges different from each other with the objects, respectively. When light reflected by a finger is received by light-receiving elements of the sensor array, the display system calculates the number of the light-receiving elements that have received the reflected light, identifies one object associated with the numerical value range including the calculated number of the light-receiving elements, from among the objects, based on the calculated number of the light-receiving elements and the stored data, and performs processing corresponding to the identified object.

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.
