Embodiment Construction

[0057] Figure 1A and Figure 1B It is a schematic side view of an electronic device according to an embodiment of the present invention. Please refer to Figure 1A and Figure 1B , the electronic device 100 of this embodiment includes a display 120 disposed on the operation plane A for illuminating the operation plane A. Furthermore, the display 120 has a first light outlet area A1 and a second light outlet area A2, wherein the illuminance of the first light outlet area A1 to the operation plane A is smaller than the illuminance of the second light outlet area to the operation plane A. The electronic device 100 of this embodiment is illustrated by taking a notebook computer as an example, but the present invention is not limited thereto. In addition, the display 120 is, for example, rotatably connected to the base 110, and the display 120 can turn the electronic device 100 into a folded state by rotating relative to the base 110 (such as Figure 1A the state shown) and the ...

Abstract

An electronic device including a display is provided. The display is disposed above a being illuminated surface to illuminate the being illuminated surface. The display has a first light exiting area and a second light exiting area, wherein illumination of the being illuminated surface contributed by the first light exiting area is smaller than illumination of the being illuminated surface contributed by the second light exiting area.

Description

technical field [0001] The invention relates to an electronic device. Background technique [0002] In general, an electronic device (such as a notebook computer) has a display and a base, and the base may include a keyboard of the notebook computer, wherein the keyboard is usually illuminated by an external ambient light source so that the user can clearly Accurately identify the words on the keyboard and the position of each key. In order to allow the user to recognize the keys for operation in a dark environment, the current technology is to arrange a backlight under the keyboard, for example, a backlight using light emitting diodes. [0003] The light emitted by the backlight can shine upwards on the bottom of the key, and the light can be transmitted through the translucent symbols or characters on the key, so that the user can still recognize the key for operation in a dark environment. Since this method needs to configure an additional backlight under the keyboard, ...
