When the housing 420 is in the upright mode (as shown in Figure 4a), the mercury droplets 410 are located at the bottom of the housing 420 and simultaneously contact one of the two conductive portions 422 and 424 to form a passage-like bear. Conversely, when the housing 420 is in the horizontal mode (as shown in FIG. 4b), the water droplets 410 are no longer in contact with the two conductive portions 422 and 424 at the same time, thereby forming a disconnected state. The financial bank will output the first or second switching signal according to the above-mentioned disconnection state.

Referring to FIG. 4a, the automatic switching unit 220 is, for example, a mercury switch disposed on the display unit 210 of FIGS. 3a and 3b. Wherein, the mercury switch 400 seals a mercury drop 410 in a casing 420, and the casing 42 〇 =.

More specifically, the mercury switch 400 outputs a first switching signal or a second switching signal as the display unit 210 turns. In addition, the automatic switching unit 220 of the present embodiment further adds a hysteresis switch having a function of extending the critical point switching time between the first and second display modes. If the user wants to change the display unit 210 in the straight or horizontal display mode, the automatic switching unit 220 will continuously change the rotation angle of the display unit 21 while being rotated by the user, and output at the critical point. The unstable switching signal is, for example, continuously outputting the first switching signal and the second switching signal repeatedly. Therefore, the display mode of the liquid crystal display panel 212 of the display unit 21 is constantly switched between the first display mode and the second display mode' thus forming an unstable and unreadable state. FIG. 5a and FIG. 5b are block diagrams showing the electronic switch with the screen switching function of FIG. 2 attached with a hysteresis switch. Among them, the hysteresis switch of Fig. 5a is, for example, a mechanical hysteresis switch 262, and the hysteresis switch of Fig. 5b is, for example, a late, vehicle body 264. Referring first to Fig. 5a, the mechanical hysteresis switch 262 is disposed between the paths of the automatic switching unit 220 for transmitting switching signals to the display unit 21A. Therefore, during the rotation of the display unit 21 〇 by the user, the user can turn on the mechanical hysteresis switch 262 to transmit one and have a late = sign to the display unit 21 〇, so that the display unit 21 〇 i liquid crystal; ^ ^ 12 The display mode can be maintained in a stable state. Wherein, the hysteresis is: for example, after a fixed switching signal continues for an appropriate period of time, the switching signal is regarded as valid, and the display mode of the liquid page display panel 212 of the display unit 210 can be switched, so that the liquid crystal is displayed. The display panel 212 will not have 128112 total ^wf.d〇c/g and will have an unstable and unreadable display state. In the above, the mechanical hysteresis switch 262 can set the mechanical hysteresis switch 262 on/off by pressing the input interface 230 of the electronic device or by selecting a touch button (not shown) on the screen. Features. Referring to Fig. 5b, it can be seen from the figure that the hysteresis software 264 is built into the display unit 21', wherein the function of the hysteresis software 264 is the same as that of the mechanical hysteresis switch described above, and therefore will not be described again.

Referring to FIG. 6a, the embodiment is similar to the first embodiment, except that the automatic switching unit 220 of the first embodiment is a mercury switch 4 and the automatic switching unit 22 of the embodiment is coupled by an optical coupling. The switch 5A and a gravitational structure 240 are formed. The optical coupling switch 5 is disposed on the display unit 210, and the gravity structure 240 is used to block the light source emitted by the optical coupling switch 5. In addition, one end of the gravitational structure 240 can be suspended on the display unit 210 to suspend the fixed point 25〇, and the other end appropriately shields the light source transmission of the optical coupling switch 500. The field automatic switching unit 22A is transmitted by the optical coupling switch 500, and the source is shielded by the gravity structure 240 as the first switching signal or the output of the first switching signal. Therefore, the present embodiment uses the above characteristics of the optical coupling switch 500 to be disposed in the display unit 21A. When the display unit 210 is in the straight mode (as shown in FIG. 3a), the liquid crystal display panel 212 displays a straight type. The display mode, and the light source 12 S112^Q) twf.d〇c/g emitted by the optical coupling switch 500, is blocked by the gravitational structure 240 (as shown in FIG. 6a). When the user rotates the display unit 210 to the horizontal mode (as shown in the north), the arrangement mode of the optical coupling switch 5〇〇 in the display unit 21〇 is also changed to the horizontal mode (as shown in FIG. 6b). The arrangement mode of the gravitational structure 24〇 in the display unit 21〇 does not change due to gravity, so the light source emitted by the handle closure is not obscured by the gravitational structure 24〇. Therefore, the optical coupling switch 2 can output the first switching signal or the second switching signal by the change of the above mode (steering of the display unit 210). The driving device 214 changes the display mode (the straight display mode or the horizontal display mode) of the liquid crystal display panel 212 of the display unit 21 by the first or the first switching signal. In the field of application, the screen switching device of the present invention can be applied to various electronic devices having a screen display function, such as a liquid crystal/plasma display, a digital camera, a dual screen/single screen mobile phone, Navigator and personal digital assistant for Xigong Month. As described above, in the present invention, a fluorescent device disposed on the display unit is applied: the switching device is arranged such that the screen display mode can automatically switch the display mode of the screen to a suitable use view as the user rotates the display list== It is displayed in the Ϊ-style display mode or the horizontal display mode) without manually setting the setting value of the P ^ screen player mode. In this way, when the user switches from manual switching to automatic switching mode, the system can switch to different display modes according to the steering P of the display unit, because::: the user adjusts to suit the browsing itself. The mode also eliminates the inconvenience of the user's own screen display mode setting. 13 1281 ... Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the invention, and those skilled in the art can make some modifications and refinements without departing from the spirit of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims. π [Simple description of the drawing] A drawing of La is not a conventional intention that a personal digital assistant is in a straight mode.
