According to the illustration of FIG. 9, there are three course touch buttons displayed on the screen, but the number of course touch buttons to be displayed can be set to two or one according to the user's preference. . Thereby, the user can perform a quicker operation.

  However, according to experience, the displayed course touch buttons are usually set to about three so that the user can feel the inconvenience of using different driving courses. The touch button can be visually recognized accurately and is easy to operate.

  In this way, by extracting and displaying the course touch button displayed on the first screen after the power is turned on, the user can operate many times to display the course touch button of the driving course that the user wants to select on the screen. There is no need to do it. It is possible to arrange so that the control means extracts and displays the driving course that is frequently used by the user and can easily operate the first screen. Therefore, even when the washing machine is multifunctional and there are various driving courses, the operation can be started with a small number of operations, and the operability is greatly improved.

  As described above, the operation display device of the washing machine according to the present invention makes it easy for the user to find a touch button that the user wants to touch, reduces the number of operations, and greatly improves operability. It can also be applied to household electrical equipment.
