摘要:
In an information recording medium in which storage capacity per recording layer has increased so much that the size of an SBM varies with those of spare areas, there is mutual dependence between a DDS and an SBM and it is difficult to retrieve disc management information as intended. In an information recording medium according to the present invention, if the largest space is allocated to an user data area, the number of blocks to store a space bitmap is Ni (where Ni≧2). But if the smallest space is allocated to the user data area, the number of blocks to use is smaller than Ni. In such an information recording medium, if the number of blocks to store the space bitmap of a recording layer is Mi (where 1≦Mi≦Ni) and if Mi is equal to or greater than two, the space bitmap is divided into the 1st through Mith space bitmaps, each of which has a size that is still equal to or smaller than one block even when combined with a DDS, and each space bitmap is stored in an associated one of Mi blocks in a disc management area.

There is provided a display device capable of preventing a malfunction and a display defect due to an off-leak from occurring even when a circuit in a shift register is configured utilizing thin film transistors of relatively large off-leaks. In at least one embodiment, each of bistable circuits that constitute the shift register includes: a thin film transistor for increasing a potential of an output terminal based on a first clock; a thin film transistor for decreasing the potential of the output terminal; a thin film transistor for increasing a potential of a range netA connected to a gate terminal of the thin film transistor based on a start signal; thin film transistors for decreasing the potential of the range netA; a capacitor for increasing the potential of a range netB connected to a gate terminal of the thin film transistor; and a thin film transistor for decreasing the potential of the range netB.

If a defective cluster in a spare area is managed with a defect entry, the size of a DFL will increase as the size of the spare area increases with an increase in the number of recording layers stacked in a disc. An information recording medium according to the present invention has pointer information indicating the location of the next available cluster in each spare area, and restricts the direction in which the spare area is used. Also, a defect entry indicating a defective cluster in the spare area is registered with the DFL. Thus, even if the size of the spare area 15 increases, the size of the DFL 21 can be kept relatively small. Furthermore, even after physical reformatting is done, a defective cluster, if any, in the spare area 15 can still be recognized as a defect and the control operation can be performed so that a replacement cluster is not re-allocated to that defective cluster (i.e., the defective cluster is not used).

Stability of a circuit operation in a monolithic gate driver is improved. A bistable circuit is provided with a charge replenishment circuit (71) including: a capacitor (CAP2); a thin-film transistor (MA) having a first electrode supplied with a first clock for charge replenishment (CKA), a second electrode connected to a third-node (N3) connected to one end of the capacitor (CAP2), and a third electrode connected to a second-node (N2) to be maintained at the high level during a normal operation period; and a thin-film transistor (MB) having a first electrode supplied with a second clock for charge replenishment (CKB), a second electrode supplied with a high-level DC power supply potential (VDD), and a third electrode connected to the third-node (N3). The first clock for charge replenishment (CKA) and the second clock for charge replenishment (CKB) are alternately driven to the high level so as to eliminate a period in which “the first clock for charge replenishment (CKA) is at the high level and the second clock for charge replenishment (CKB) is at the high level”.

According to the present invention, multiple space bitmaps (SBMs #0 and #1 30) are provided for the user data area of each recording layer. A disc management structure update unit including one of those space bitmaps and a disc definition structure (TDDS 32) and having a size of one block is written on a management information area (TDMA 17). As a result, data including the disc definition structure (TDDS 32) can always be arranged in the first block at the top of the management information area (TDMA 17).

A peripheral region of a display panel includes a signal distribution device (4) for time-dividing and distributing, to output terminals (7), an output signal from a source driver. The signal distribution device (4) includes switching elements (20) for the output terminals (7). Each switching element (20) is controlled by a selection signal supplied to a control line (9) connected with a gate electrode. Each switching element (20) includes a source electrode and the drain electrode each having a comb-like shape having a stem part and branch parts extending therefrom. In at least one switching element (20), only all of or part of the branch parts overlap the control line (9) and a semiconductor layer (10). This suppresses abnormal heat generation of a source driver in a display device including the signal distribution circuit by which an output signal from the source driver is distributed to pixels in time series.

摘要:
To achieve more appropriate interpolation of a missing pixel, an image is input to a processing section for interpolation. The interpolation is applied utilizing image data of pixels located around the pixel to be interpolated. Specifically, correlations between the image data of the pixels to be interpolated, and pixel data in a horizontal direction, vertical direction, and diagonal direction, are compared to one another; pixel data having stronger correlation is used for the interpolation. Correlation between the image data of the pixels to be interpolated and which direction is strong is determined, so that different weighting for interpolation is used accordingly.
