2. Description of Related Art

Through the improvements of semi-conductor components and display technology, electronic devices are now being developed to be smaller, multi-functioned, portable, and convenient. Common portable electronic devices include personal digital assistants, mobile phones, and notebook computers. Portable electronic devices can use a foldable method to save area, in order to achieve the objective of compactness.

Using the notebook computer as an example, a common notebook computer is assembled with a main body and a display, wherein the main body and the display are pivoted relatively. The user can shut together the main body and the display of the notebook computer through the relative pivoting between the main body and the display in order to be conveniently portable. When use of the notebook computer is desired, the display can be opened up and operated conveniently. In detail, the display includes a back cover, a bezel and a display panel. The display panel is assembled between the back cover and the bezel, and is exposed by an opening in the bezel, so the user can see the display images. Besides the surface of the display facing the user having a display panel, the display further includes bezel parts surrounding the display panel. If a light emitting element can be disposed on the bezel parts to display scene light, then the user can see the display images with better visual comfort.

FIG. 1andFIG. 2are three-dimensional schematic views of a display according to an embodiment of the invention. Please refer toFIG. 1andFIG. 2. The display100of the embodiment is suitable to assemble on a main body50of a portable electronic device. The display100includes a back cover110, a bezel120, and a display panel130. The portable electronic device is for example, a notebook computer.FIG. 3is a partial schematic cross-sectional view of the bezel inFIG. 1. Please refer toFIG. 1andFIG. 3. The bezel120includes a frame122and an electroluminescent light (EL) source layer124. The frame122is assembled to the back cover110and includes an opening122a. The electroluminescent light source layer124is attached to the frame122and surrounds the opening122a. The display panel130is assembled between the back cover110and the frame122and is exposed by the opening122a.

The electroluminescent light source layer124is electrically connected to the main body50. The main body50is suitable to control the electroluminescent light source124to emit light, which is used to display scene light, letting the user see the displayed images with more visual comfort. Since the electroluminescent light source layer124is flexible, it can undergo cutting or bending without affecting the luminescence performance and can achieve a uniform lighting effect without a light guide plate or other optical elements. Furthermore, the electroluminescent light source layer124is a cold light source, and can avoid the display100from overheating while displaying scene light. Also, the electroluminescent light source layer124is a low power consumption light emitting element, and thus has a power saving advantage.
