Detailed Description

To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

Fig. 1 is a schematic front view structure diagram of a terminal according to an embodiment of the present disclosure. As shown in fig. 1, the terminal includes a display 1 and a frame 2. The frame 2 surrounds and is connected to the display screen 1.

Fig. 2 is a schematic partial cross-sectional view of a terminal according to an embodiment of the present disclosure. As shown in fig. 2, the display screen 1 includes a top surface 11, side walls 12, and a frame engaging surface 13. The side wall 12 surrounds the top surface 11, and the frame engagement surface 13 is connected between the top surface 11 and the side wall 12 in a direction perpendicular to the display screen 1. The frame 2 has a display screen engaging surface 21 that matches the frame engaging surface 13.

In the embodiment of the present disclosure, the top surface 11 of the display screen 1 is a light exit surface of the display screen 1, i.e., a surface opposite to an observer.

Because the lateral wall of display screen centers on the top surface setting of display screen, the frame composition face is in the direction of perpendicular to the display screen connect in the top surface of display screen with between the lateral wall of display screen, consequently, the frame composition face is in the sunken state for the top surface of display screen, and the frame composition face of frame matches with the frame composition face on the display screen, and like this, the border region of a part of display screen can be sheltered to the frame for the non-display area of the display screen that the people can see narrows down, can't see the non-display area of display screen completely even, thereby satisfy the development trend of terminal narrow frame. Moreover, the frame can press the edge of the display screen from the top surface of the display screen, and plays a certain role in protecting and fixing the display screen.

As shown in fig. 2, the display screen further includes a bottom surface 14, the bottom surface 14 is disposed opposite to the top surface 11, the side wall 12 and the frame engaging surface 13 are both located between the top surface 11 and the bottom surface 14, and the top surface 11 and the bottom surface 14 are connected by the frame engaging surface 13 and the side wall 12. The orthographic projection of the frame engaging surface 13 on the bottom surface 14 is located between the orthographic projection of the top surface 11 on the bottom surface 14 and the orthographic projection of the side wall 12 on the bottom surface 14.

Alternatively, the side walls 12 of the display screen 1 may be planar, e.g. perpendicular to the top surface 11, in which case the outer contour shape and size of the various layer parts of the display screen in a plane parallel to the display screen are the same.

Alternatively, the side walls 12 of the display screen 1 may also be stepped or irregular surfaces, in which case at least one of the outer contour shape and size in a plane parallel to the display screen of the respective layer components of the display screen is different. For example, as shown in FIG. 2, the edge of the top half of the display screen (typically the cover glass) extends beyond the edge of the bottom half of the display screen (typically the display module) in a direction parallel to the display screen.

Alternatively, the display screen 1 may be a liquid crystal display screen or an OLED (Organic Light-Emitting Diode) display screen.

The liquid crystal display generally includes a display module and a backlight module, wherein the display module includes a first substrate and a second substrate which are arranged oppositely, and a liquid crystal layer located between the first substrate and the second substrate. The first substrate may be an array substrate, and the second substrate may be a color film substrate. The OLED display screen generally includes a display module including an array substrate and an OLED light emitting device disposed on the array substrate.

Illustratively, the display screen 1 may comprise a cover glass, the frame engaging surface 13 being located at an edge of the cover glass. For the lcd, the cover glass may be a substrate of the second substrate, i.e. the cover glass is integrated as a part of the display module, or may be a layer of glass additionally attached to the second substrate, i.e. the cover glass covers the display module. For OLED displays, the cover glass typically covers the display module. The frame joint surface is arranged on the cover plate glass, so that the processing is easy to realize, and the influence on components such as a display module can be avoided.

Optionally, when the cover glass covers on the display module, the side of the cover glass can be left with allowance, namely, in the direction parallel to the display screen, the side of the cover glass exceeds the side of the display module, so that the display module is prevented from contacting with the frame, and a certain protection effect is achieved on the display module.

In implementation, a frame joint surface can be machined on the edge of the cover glass by adopting a CNC (computer Numerical Control) machining mode.

The frame is divided into a middle frame and a front shell decorating part, so that the frame and the display screen can be assembled conveniently.

Illustratively, the lower portion of the front garnish 23 and the center frame 22 may be bonded together. For example, the adhesive can be glued together by means of glue. As shown in fig. 2, the lower portion of the garnish 23 and the center frame 22 are bonded by glue 24.

Further, the front trim 23 may include a support frame 231 and a defining edge 232 extending from one end of the support frame 231 to a middle portion of the support frame 231, the other end of the support frame 231 is fixedly connected to the middle frame 22, and the display screen engaging surface 21 is a side surface of the defining edge 321 connected to an inner wall 231a of the support frame 231 (i.e., a side wall opposite to the display screen).

In one possible implementation, the thickness of the frame as seen from the display surface of the display screen of the terminal is the sum of the maximum thickness of the support frame 231 in the direction parallel to the display screen 1 and the width of the display screen engaging surface 21 in the direction parallel to the display screen 1.

Alternatively, the outer sidewall of the support frame 231 may be provided with a ring of recesses, and the edge of the middle frame 22 may be provided with a ring of protrusions, which are located in the recesses when the front housing decoration 23 is coupled to the middle frame 22. This engagement can more securely connect the center frame 22 and the front garnish 23.

Alternatively, the outer side wall of the front cover garnish 23 may be flush with the outer side wall of the center frame 22, so that the center frame is not visible when the terminal is viewed from the display surface of the display screen of the terminal, and the width of the visible bezel can be further reduced.

Alternatively, the outer side wall of the middle frame 22 may protrude from the outer side wall of the front housing garnish 23.

Illustratively, the outer side wall of the front housing decoration 23 is a smooth curved surface to reduce damage caused by collision. For example, the junction of the defining edge 232 and the support frame 231 is rounded.

Alternatively, the front housing decoration 23 may be a plastic member to avoid scratching the display screen and protect the edge of the display screen. For example, the front garnish 23 may be made of nylon or glass fiber. In practice, the front case garnish 23 may be injection molded.

Alternatively, the middle frame 22 may be an aluminum alloy member. The aluminum alloy member is light and has a certain rigidity to support the respective parts of the terminal.

In the embodiment of the present disclosure, the top surface of the frame 2 and the top surface 11 of the display screen 1 are in the same plane, so that the wear caused by the uneven top surface of the terminal can be reduced, and the terminal has a more beautiful appearance and a better hand feeling.

Optionally, the display screen engaging surface 21 and the frame engaging surface 11 are bonded to each other to more securely couple the display screen and the frame together.

The frame joint surface 13 is at least partially located in the non-display area 1b, which means that the orthographic projection of the frame joint surface 21 on the display screen 1 completely or partially coincides with the occlusion area. Illustratively, in fig. 2, the frame engagement surface 13 is partially located in the non-display area 1 b. After the frame joint surface 13 is bonded to the display screen joint surface 21 on the frame 2, the display screen joint surface 21 can at least shield part of the peripheral area, so that the black edge of the display screen is reduced, and the black edge of the display screen is narrow or even cannot be seen.

Illustratively, the width of the display screen engaging surface 13 in a direction parallel to the display screen 1 is 0.2mm to 1mm, for example 0.4mm to 0.5 mm. The width can ensure that the display screen can be stably installed in the frame under the condition that other connection modes are not adopted between the display screen joint surface and the frame joint surface.

Illustratively, in the embodiment shown in FIG. 2, the frame engaging surface 13 is a beveled surface. The display screen engaging surface 21 is also beveled in order to match it.
