Similarly, when the first voltage is applied to the second-type electrode 622 and the second voltage is applied to the third-type electrode 623, the second-type electrode 622 and the corresponding common electrode make part of the internal display area 82 in a fully transparent state, and the third-type electrode 623 and the corresponding common electrode make part of the internal display area 82 in a fully display state, where the fully display state is in sharp contrast with the fully transparent state, so that the frosted glass state formed by the third-type electrode 623 and the corresponding common electrode can display information similar to weather, step number, incoming call, time and the like.
It should be noted that the second-type electrode 622 integrally receives a potential signal, and the third-type electrode 623 is to realize the display of different information on the display screen, so that the whole third-type electrode 623 does not receive the same point location at the same time, for example, as shown in fig. 7, when a phone enters a mobile phone connected to the watch 100 provided by the present application, the third-type electrode 623 corresponding to the phone shape on the display screen and the second-type electrode 622 in the internal display area receive different potentials, so that the display states of the display screen corresponding to the third-type electrode 623 and the second-type electrode 622 in the phone shape are controlled to be a full display state and a full transparent state respectively, so as to form a sharp contrast, and a user can receive a new incoming call prompt from the watch; accordingly, when there is no new call, the second-type electrode 622 and the third-type electrode 623 in the shape of a telephone receive the same potential, for example, both receive a high-frequency voltage, and at this time, the display screens corresponding to the second-type electrode 622 and the third-type electrode 623 in the shape of a telephone all display a fully transparent state.
For example, as shown in fig. 8, the three-type electrodes 623 in the shape of "88" may be formed by 7 three-type electrode sub-electrodes, and when different time needs to be displayed, the three-type electrode sub-electrodes and the two-type electrode 622 corresponding thereto may be controlled to receive the same potential or different potentials.
By enabling the display panel 20 of the mechanical watch 100 with the display screen provided by the application to comprise the edge display area 81 and the inner display area 81, the edge display area 81 and the inner display area 82 both comprise a full transparent state and a full display state, and by controlling the second-type electrode 622 and the third-type electrode 623 in the inner display area 82 to receive the same or different electric potentials, diversified information display of the inner display area 82 is realized. The display screen and the mechanical watch 100 are beneficial to achieving diversified display effects, avoiding the situation that information such as time can be acquired through the mechanical pointer 10 when the electric quantity of the display screen is exhausted, and achieving customized display effects of the watch 100 by manually controlling the display screen to be in a transparent or display state.
