Abstract
A display comprises a relatively large plurality of picture elements in each of the vertical and horizontal directions, with which characters are displayed with a relatively less plurality of picture elements in each of the vertical and horizontal directions. In order to store the data to be displayed with the above described display, a refresh memory is employed. The refresh memory is used such that the respective areas thereof storing portions of the character are addressed in synchronism with the period of a character clock, whereby the character data to be displayed is read out therefrom. Each portion of the character data as read out from the refresh memory is latched in a latch circuit during the character clock period and is kept supplied to the display. The refresh memory serves to renew portions of the character at an arbitrary timing during the display period by the display or during the blanking period where display is not made by the display.
