  • Patent number: 11967294
    Abstract: A common electrode driver includes an inverting amplifier including a first resistor, a second resistor, and an operational amplifier, and a resistance ratio adjustment circuit that adjusts, in accordance with a length of one horizontal scan period, a resistance ratio being a ratio of a resistance value of the second resistor to a resistance value of the first resistor. A feedback voltage is provided to one end of the first resistor. The resistance ratio adjustment circuit sets the resistance ratio when second driving is performed, in which a length of one horizontal scan period is a second time longer than a first time, to be smaller than the resistance ratio when first driving is performed, in which a length of one horizontal scan period is the first time.

  • Patent number: 11874210
    Abstract: A sample analysis substrate capable of holding a plurality of liquids. The sample analysis substrate has a microchannel structure for transferring a liquid through rotary motion, the sample analysis substrate including: a substrate body having a rotation axis; a first and a second container holding a first and a second liquid therein; a first and a second accommodating section accommodating the first and the second container; and a cap having a first and second projection and movably supported on the substrate body. As the cap moves, the first drive projection and the second drive projection move the first container and the second container with staggered timing, thereby releasing the first and the second liquid accommodated therein.

  • Patent number: 10896650
    Abstract: A short-circuiting circuit short-circuits source bus lines such that a sum of numbers assigned to two source bus lines forming each set in each group is equal for all sets when it is assumed that K consecutive source bus lines (K is an even number greater than or equal to 4) form one group and numbers from 1 to K are assigned to the K source bus lines. For example, with four consecutive source bus lines forming one group, in each group, the short-circuiting circuit short-circuits the first and fourth source bus lines and short-circuits the second and third source bus lines.
