  • Patent number: 10163392
    Abstract: The present invention provides an active matrix display device capable of producing a favorable display on a non-rectangular display unit, such as a circular display unit. In an active matrix liquid crystal display device with a circular display unit, a control signal Sck is generated so as to reduce a decrease amount ?Vsl of a data signal line voltage Vsl due to a parasitic capacitance Cgd, as a control signal of an Nch transistor (SWk) that is a switching element of a sample-and-hold circuit for sampling a video signal Svi and holding the sampled signal in a data signal line capacitance. That is, at the time of turning off the Nch transistor (SWk), a connection switch control signal Sck is generated such that the control signal Sck changes from an H-level connection control voltage VCH as an on-voltage to an L-level connection control voltage VCL as an off-voltage through a period TCI for an intermediate level voltage VCI.
