A seat frame includes: a plate member; and a bar member joined to the plate member, the bar member including a planar portion on at least part of a side surface of the bar member, wherein the plate member and the bar member are joined to each other by a welded portion including a base portion configured to: extend in a longitudinal direction of the bar member; and have a central line positioned closer to a position at which a load from a user is applied upon use of the seat frame than a central portion of the bar member, the central portion being at a center of a length of the bar member, the length being orthogonal to the longitudinal direction of the bar member, the position being in an area of contact between the plate member and the planar portion.

Seat frame

There is provided a liquid crystal display device having a liquid crystal panel including a plurality of gate lines to select a pixel and a plurality of data lines to supply pixel data, and a drive circuit dividing one frame into a plurality of fields, converting the frame data to field data, and supplying the field data to the data line.

Liquid crystal display device and driving method of the same

A liquid crystal display device including a liquid crystal panel provided with plural gate lines to select a pixel and plural data lines to supply pixel data and a data driver dividing a single frame into plural fields and converting frame data into field data to supply the field data to the data line is provided. When the frame data has a tone change, the data driver performs correction to data of an odd-number field of the frame in a same direction as an increase/decrease direction of the tone change of the frame data, and performs correction to data of an even-number field of the frame in an opposite direction to the increase/decrease direction of the tone change of the frame data.

Liquid crystal display device having a plurality of subfields

A liquid crystal display aimed at improving response speed, movie characteristics and viewing angle dependence of gradation is provided as having a liquid crystal panel including a plurality of gate lined selecting pixels and a plurality of data lines supplying pixel data, and a data driver dividing one frame into a plurality of fields to thereby convert a frame data into a field data, and supplying the field data to the data line, wherein in the last field out of the plurality of fields, the data line is applied with a first constant voltage, for the frame data ranging from the minimum gradation value to a first gradation value, and in the top field out of the plurality of fields, the data line is applied with a second constant voltage larger than the first constant voltage, for the frame data ranging from a second gradation value to the maximum gradation value.
