摘要:
An electrooptic device includes first and second substrates that are disposed opposing each other with an electrooptic material layer therebetween, a sealing material that bonds the first and second substrates, a pixel area, and an ion trap portion between the pixel area and the sealing material. The ion trap portion includes first and second electrodes that are formed in a comb-tooth shape and are disposed so that branch electrodes of the first electrode and branch electrodes of the second electrode are engaged with each other. A direction of the branch electrodes intersects with an orientation direction of the electrooptic material at an interface between the electrooptic material layer and the first substrate.
摘要:
A CPU perform the steps of: (a) causing a compression/decompression processor to decompress the compressed data of one of three bands in the data area except for the first block in the band, and storing decompressed bitmap data in the data area; (b) rasterizing each of the intermediate data blocks in the band and synthesizing the rasterized data and the decompressed bitmap data in the band; and (c) causing the compression/decompression processor to compress the synthesized bitmap data and storing the compressed data in the data area. The CPU performs the steps (a) to (c) in different respective tasks in parallel, and performs the steps (a) to (c) along the order of (a), (b), (c) for each of the intermediate code blocks in each of the bands while using the 1st to the 3rd bitmap data area in turn for each of the steps (a) to (c).
