Description

Display device, frame module, and frame module manufacturing method

technical field

The invention relates to a frame module used for a display device, in particular to a frame module capable of easily producing different opening sizes.

Background technique

With the advancement of display technology, displays are becoming thinner and lighter with more diverse sizes. From small-sized 1-inch OLED panels to large-sized 150-inch plasma panels, there are corresponding electronic products on the market, such as Walkmans and TVs. Generally speaking, the frame for accommodating the display panel and the circuit connected to the display panel needs to be redesigned and manufactured according to the size of the display panel. In other words, display panels of different sizes correspond to frame designs of different sizes.

Generally speaking, for display panels with large size differences, it is natural to redesign and manufacture different frame mechanisms. However, in recent years, the size difference of display panels has become smaller and smaller. Taking small notebook computers as an example, there were only 12-inch designs in the early days. In recent years, 5.6-inch, 7-inch, 8.9-inch, and 10.2-inch specifications have appeared. Display panels with little difference make different frames. In addition, the early display panels were all in a 4:3 ratio (that is, the aspect ratio of the display area was 4:3), but the current display panel has a 16:9 or 16:10 ratio to meet the economic benefits and economic benefits of panel manufacturers. The golden ratio for the best vision. Therefore, the 21-inch specifications may have 21.1 inches (16:10 ratio), 21.3 inches (4:3 ratio) and 21.5 inches (16:9 ratio).

Therefore, in the case of small size differences (such as the above-mentioned multiple specifications of 21 inches), it is quite uneconomical to produce and design frames of various corresponding sizes. In the fast-changing technological field, the size requirements of display panels also change rapidly, so it is easy to cause excessive inventory of frames with existing specifications. Moreover, frames of different sizes cannot be shared, resulting in an increase in the overall production cost.

In order to diversify the products, the specifications of the same electronic products will be changed to meet different consumer demands. However, in order to save the cost of mold opening and mechanism design, usually a larger-sized mechanism design is used to install other smaller-sized display panels. Taking a notebook computer as an example, as shown in FIG. 1 , a frame 10 (or top cover) of the same size may be equipped with display panels D ₁ , D ₂ and D ₃ of three different sizes, such as 7 inches, 8.9 inches and 10.2 inches, and then can quickly manufacture three notebook computers with different specifications.

However, the opening design of the frame 10 of the notebook computer can only be matched with one of the sizes of the display panels _D1 , _D2 , and _D3 , so installing display panels of different sizes still requires additional mold opening to produce frames with different opening sizes, which is not effective. Reduce the production and design costs of the frame.

Contents of the invention

In view of this, the present invention proposes a frame module, which meets the requirements of different opening sizes by directly combining the small frame with the large frame, meets the design value of the shared display panel, and does not need to re-open the mold for the entire frame module, and then Reduce design and production costs.

An object of the present invention is to provide a frame module and a frame module manufacturing method, which can manufacture frame modules with different opening sizes at a lower cost and in a shorter time to match display panels with different display sizes.

In order to achieve the above object, the frame module provided by the present invention has a first opening for exposing the display panel, and includes a main frame and a sub frame. The main frame has a second opening, and the size of the second opening is larger than that of the display panel; the sub-frame is directly formed on the inner edge of the second opening to form the first opening, and the size of the first opening is smaller than that of the display panel. The size of the first opening is used to match display panels of different sizes.

The method of making the frame module can be that the main frame and the sub-frame are molded sequentially or together, but in both ways, the sub-frame can be directly molded on the main frame and tightly combined with each other. The main frame is made of carbon fiber material, the sub-frame is made of rubber material, and the steps of forming the two in sequence are: provide the main frame, the above-mentioned main frame has a second opening, and the size of the second opening is larger than that of the display panel; then, directly form the sub-frame The first opening is formed on the inner edge of the second opening, and the size of the first opening is smaller than that of the display panel, so that the size of the first opening can be changed to match display panels of different sizes.

The main frame is made of carbon fiber material, and the sub-frame is made of rubber material, and the steps of integral molding of the two are: stacking multiple carbon fiber layers; then, hot pressing or injecting rubber material on the multiple stacked carbon fiber layers, and making the rubber material and multiple carbon fiber layers The carbon fiber layers are molded at the same time. The above-mentioned multiple carbon fiber layers are formed into the main frame, the main frame has a second opening, and the second opening is larger than the display panel, and the rubber material is formed into a sub-frame, and the sub-frame is formed on the inner edge of the second opening to form the first opening , and the size of the first opening is smaller than that of the display panel, so that the size of the first opening can be changed to match display panels of different sizes.

Another object of the present invention is to provide a display device that can manufacture frame modules with different opening sizes at a lower cost and in a shorter time to match display panels with different display sizes.

The display device of the present invention includes a display panel and a frame module, and the frame module includes a main frame and a sub-frame. The main frame has a second opening, and the size of the second opening is larger than that of the display panel; the sub-frame is directly molded on the inner edge of the second opening to form a first opening, and the size of the first opening is smaller than that of the display panel. A size of the opening to match display panels of different sizes.

To sum up, according to the size of the display panel, the present invention designs a sub-frame with an appropriate size (the first opening) and directly forms it on the inner edge of the main frame with a fixed size (the second opening). Through the rapid change of the opening size and the direct molding method of production (such as heat pressing, thermosetting or injection molding), after the main frame of the same opening size is matched with different sub-frames, frame modules with different opening sizes can be formed. In addition, the present invention can reduce the steps of assembling or bonding the frame modules, and has the advantages of fast manufacturing and cost saving. In addition, the present invention joins the main frame and the sub-frame in a one-time combination without using adhesive substances (such as glue) or locking elements (such as screws), thereby avoiding the decrease in viscosity or locking elements after long-term use. Disadvantages such as looseness.

The advantages and spirit of the present invention can be further understood by using the following detailed description of the invention and the accompanying drawings.

Detailed ways

In order to utilize the original mechanism design of the display device, simplify the production process and reduce the design and production costs, the present invention proposes a display device and its frame module, which is directly molded on the main frame with a relatively large opening size. subframe. Therefore, the present invention can design different opening sizes only by changing the opening size when the sub-frame is formed, so as to match display panels of different sizes. For example, when the purchased panel and its matched frame are both used for a 10-inch display, but if you want to develop a 7-inch display panel in the future, you can use the original 10-inch main frame to match another sub-frame, and adjust the sub-frame when forming That is to say, the opening size of the sub-frame can be adjusted according to the size of the viewing area of the 7-inch display panel without having to purchase an additional frame suitable for the 7-inch display panel, which shows that the present invention can effectively reduce the production cost.

Please refer to FIG. 2A , which is a schematic diagram of a display device 3 according to an embodiment of the present invention. As shown in FIG. 2A , the display device 3 includes a display panel 34 and a frame module, and the frame module includes a main frame 30 and a sub-frame 32 . The frame module has a first opening O ₁ to expose the visible area of the display panel 34 . The main frame 30 has a second opening _O2 (the space surrounded by the main frame 30), and the sub-frame 32 is directly formed on the inner edge of the second opening _O2 to form the first opening _O1 (the space surrounded by the sub-frame 32) .

Wherein, the size of the second opening _O2 is greater than the size of the display panel 34 in order to match the design value of the display panel to be shared, and the size of the first opening _O1 is smaller than the size of the display panel 34, but slightly larger than that of the display panel 34. The size of the viewing area. In the present invention, the sub-frame 32 can be used to fill the size difference between the display panel 34 and the second opening _O2 of the main frame 30, forming a size smaller than the first opening _O1 of the display panel, so that the display panel 34 can be firmly placed in the frame module Inside.

As shown in FIG. 2B , the structure of the main frame 30 can extend a protruding structure toward the space it surrounds, and the sub-frame is formed on the protruding structure to completely cover the protruding structure, so as to strengthen the connection between the main frame 30 and the sub-frame 32. Bond strength. In addition, the main frame 30 can be made of materials such as metal, plastic or carbon fiber, and the sub-frame 32 can be made of materials such as plastic or rubber. The following process of manufacturing the frame module of the present invention will take the carbon fiber main frame and the rubber sub-frame as examples.

Please refer to FIG. 3A to FIG. 3C . FIG. 3A to FIG. 3C are schematic diagrams showing a manufacturing method of a frame module according to a specific embodiment of the present invention. As shown in FIG. 3A to FIG. 3C , the manufacturing process of the frame module is described in detail as follows.

First, as shown in FIG. 3A, the formed main frame 30 is placed in the first mold _M1 . In practical applications, multiple carbon fiber layers can be stacked first, and then the stacked carbon fiber layers can be formed into the main frame 30 by hot pressing or thermosetting process. During the thermoforming process, the carbon fiber layer can be cut out to form the second opening O ₂ . Alternatively, the formed and solidified carbon fiber layer is then cut to form the second opening O ₂ . The material of the main frame 30 can be metal or plastic besides carbon fiber. For example, the metal sheet is formed into a metal main frame by a stamping process, and the metal sheet is punched out to form a second opening during the stamping process. Alternatively, the plastic is molded into a plastic main frame in an injection molding process.

Next, as shown in FIG. 3B , the rubber material 320 is placed inside the main frame 30 . A piece of rubber material 320 is placed on each of the four inner sides of the main frame 30 to facilitate the subsequent heat-pressing process. These rubber materials can be fused together to form the sub-frame 32 shown in FIG. 2A . In another embodiment, a piece of rubber material can also be placed on only one of the inner sides of the main frame, so that the rubber material is only molded on one of the inner sides of the main frame.

In other words, the sub-frame of the present invention is not limited to the closed shape shown in FIG. 2A, and can also be formed only on the left and right sides or the top and bottom sides of the second opening _O2 of the main frame 30. For example, the ratio of the second opening is 16: 9. After the sub-frame is formed on the left and right sides of the second opening, the first opening with a ratio of 4:3 can be formed. Even, the sub-frame can only be formed on one of the inner sides of the second opening _O2 of the main frame 30, for example, the size of the second opening is 21.5 inches (16:9 ratio), and the sub-frame is formed on the left side of the second opening After that, the first opening with a size of 21.1 inches (16:10 ratio) can be formed. In a word, according to the size of the display panel and the overall design of the display, the sub-frame can be formed on different inner sides of the main frame to meet the design requirements of the actual product.

Next, as shown in FIG. 3C , the second mold M ₂ is pressed against the first mold M ₁ to extrude the rubber material 320 to form the sub-frame 32 on the main frame 30 . There is a space with a specific shape and size between the second mold _M2 and the first mold _M1 . When the second mold _M2 is pressed toward the first mold _M1 , the rubber material 320 will be squeezed into these spaces. While extruding, parameters such as temperature, time and pressure can be controlled, so that after the rubber material 320 is solidified, a sub-frame 32 of a specific size and shape can be directly formed on the main frame 30 . Therefore, the sub-frame 32 is directly combined with the main frame 30, and there is no need for a locking element to provide a fixing force for combining the two. After that, the second mold M ₂ is separated from the first mold M ₁ to complete the frame module shown in FIG. 2 .

The above describes the manufacturing process of first forming the main frame 30 and then hot pressing the sub-frame 32 . The manufacturing method of the frame module of the present invention also includes other methods, please refer to the following description.

The main frame and the sub-frame are hot-pressed at the same time:

First, a plurality of uncured carbon fiber layers are stacked on the first mold. Next, a rubber compound is placed over the layers of carbon fiber. Then, press the second mold towards the first mold, and control parameters such as temperature, time and pressure, so that multiple carbon fiber layers are hot-pressed into the main frame, and rubber materials are hot-pressed into the sub-frame. Afterwards, the second mold is separated from the first mold to take out the frame modules that have been combined. It should be added that in order to make the extruded rubber material more smoothly combined with the side of the second opening of the main frame, the second opening can be cut out for the carbon fiber layer during the hot pressing process, or the The uncured carbon fiber layers are cut to form the second opening before being placed on the first mold.

The main frame is formed first, and the sub-frame is then injection molded:

Firstly, the formed main frame is placed on the first mold. The forming method can be seen from the above description, and will not be repeated here. Next, press the second mold towards the first mold, and there is a gap of a specific shape between the second mold and the first mold as a space for rubber injection. Moreover, the second mold includes an injection hole for introducing rubber material into the injection space. Next, the rubber material is injected into the injection space through the injection hole and parameters such as temperature, time and pressure are controlled, so that the rubber material is directly molded on the main frame to form a sub-frame. Afterwards, the second mold is separated from the first mold to take out the frame modules that have been combined.

The sub-frame is injection molded while the main frame is thermoset:

First, a plurality of uncured carbon fiber layers are stacked on the first mold. Next, press the second mold towards the first mold, and there is a gap of a specific shape between the second mold and the first mold as a space for rubber injection. Moreover, the second mold includes an injection hole for introducing rubber material into the injection space. Next, the rubber material is injected into the injection space through the injection hole, and parameters such as temperature, time and pressure are controlled, so that the main frame and the sub-frame are formed simultaneously. In other words, through the pressure and heat of the injection material, the carbon fiber layer contacting the injected rubber material is thermoset to the main frame, and the rubber material is also cured to form the sub-frame. Afterwards, the second mold is separated from the first mold to take out the frame modules that have been combined.

The above two sequential molding methods and the two simultaneous molding methods all take carbon fiber and rubber materials as examples. If the main frame is made of metal and the sub-frame is made of plastic, it can be applied to the above-mentioned sequential molding and simultaneous molding processes. If the main frame is made of plastic material and the sub-frame is made of rubber material, it is a better choice to apply the above sequential molding process.

To sum up, according to the size of the display panel, the present invention designs a sub-frame with an appropriate size (the first opening) and directly forms it on the inner edge of the main frame with a fixed size (the second opening). Through the rapid change of the opening size and the direct molding method of production (such as heat pressing, thermosetting or injection molding), after the main frame of the same opening size is matched with different sub-frames, frame modules with different opening sizes can be formed. In addition, the present invention can reduce the steps of assembling or bonding the frame modules, and has the advantages of fast manufacturing and cost saving. In addition, the present invention joins the main frame and the sub-frame through a one-time combination without using adhesive substances (such as glue) or locking elements (such as screws), thereby avoiding the reduction of viscosity or locking elements after long-term use. Disadvantages such as looseness.
