Abstract: A timing control (TCON) board and a display device are provided. The TCON board includes a TCON chip and a CB. A plurality of heat dissipating terminals are provided to commonly connect the TCON chip to the CB, increasing a total contact area of the TCON board and the CB. Therefore, heat dissipation efficiency of the TCON chip is improved. At the same time, the heat dissipating terminals greatly reduce a pseudo connection percentage. Hence, heat dissipation performance and electrical performance of the entire TCON chip are avoided to be impacted.

Abstract: A control method of a time sequential control signal and a driving circuit are provided. A main TCON chip and an assist TCON chip compute corresponding frame rates according to pixel clock signal frequencies, then call a corresponding table, and transmit the table to a first driving unit and a second driving unit respectively. The first driving unit and the second driving unit respectively perform scanning on rows and columns of pixels to allow complicated dynamic images to be displayed with smooth motions.
