摘要： An image display apparatus includes a light-source driving circuit that drives a light source to cyclically change brightness. A control unit controls a pixel to turn on and off over a plurality of subfields in a field so that transmittance or reflectance in the pixel over the plurality of subfields in the field corresponds to a gray level specified for the pixel. The control unit also arranges the plurality of subfields such that two or more gray-level defining subfields maintain a predetermined relationship with respect to the cyclical change in brightness of the light source caused by drive of a light-source driving circuit.

摘要： Some embodiments provide a system for displaying cells of a table. During operation, the system can receive a sort-and-merge request for sorting the rows of the table using a sort column. Next, the system can sort the rows of the table based at least on cell values in the sort column to obtain a sorted table. The system can then merge a set of consecutive cells in a merge column of the sorted table to obtain a merged cell, wherein the set of consecutive cells are associated with the same cell value. Note that the sort column and the merge column can be the same column, or they can be different columns. Next, the system can display the merged cell and other cells in the sorted-and-merged table. Displaying a cell can involve positioning the cell's value in a visible area of the cell.
