Abstract
Description
Technical Field
[0001] This application relates to the field of electronic device technology, specifically to a laptop computer. Background Technology
[0002] Most laptops currently use a raised hinge structure. To ensure the strength and damping of the hinge, the raised part needs to be large enough, which prevents the laptop from becoming thinner. To make laptops thinner and more portable, and to enhance the visual experience of full-screen displays, the recessed hinge structure has gradually become a research hotspot. In the recessed hinge structure, the hinge is located in the inner layer at the rear of the main unit. When flipped, part of the display screen is lowered to a position below the horizontal plane of the main unit, which can compress the thickness of the laptop screen. However, in the existing recessed hinge structure, the PCBA board is located at the bottom bezel of the display screen, which increases the thickness of the bottom bezel and affects the overall thickness of the display, making it impossible to achieve an extremely narrow bezel.

[0027] In some embodiments of this application, a laptop computer 100 is provided, with reference to Figures 1-6The notebook computer 100 includes: a terminal body 110, a display screen 120, a connector 130, a circuit board 140, and a hinge 170.
[0028] Reference Figure 1 and Figure 2 The terminal body 110 includes a main casing 1101. The main casing 1101 includes a first surface 111 and a second surface 112 disposed opposite to each other along its thickness direction. The first surface 111 is the front of the main casing 1101, and a keyboard (not shown in the figure) and a touchpad (not shown in the figure) are disposed on the first surface 111. The second surface 112 is the back of the main casing 1101, and a heat dissipation vent can be disposed on the second surface 112. A control system (not shown in the figure) is disposed inside the main casing 1101. The control system includes a motherboard, a CPU (central processing unit), a GPU (graphics processing unit), etc.
[0029] Reference Figure 1 , Figure 2 and Figure 4 The display screen 120 includes a display section 1200 and a connecting section 130. The connecting section 130 is disposed at one edge of the display section. The display section 1200 includes a display shell 1201 facing the terminal body 110. The display shell 1201 includes a display window 1202 facing the terminal body 110. A display panel is disposed inside the display shell 1201. The display panel includes a display module 121 and a backlight module 123. The display module 121 is embedded in the display window 1202. The display module 121 has a display surface 1210 for displaying images. The display surface 1210 faces the first surface 111 of the main body shell 1101 of the terminal body 110.
[0030] In some embodiments, refer to Figures 1-4 The connecting part 130 is provided with a receiving cavity 131. The connecting part 130 includes a first segment 132 and a second segment 133 connected in sequence. The first segment 132 extends in a direction parallel to the plane where the display surface 1210 of the display module 121 is located. The end of the first segment 132 away from the second segment 133 is connected to one end of the display part 1200. The end of the second segment 133 away from the first segment 132 bends toward the terminal body 110. Specifically, the end of the second segment 133 away from the first segment 132 bends toward the main casing 1101 of the terminal body 110, so that the connecting part 130 presents an L-shape or J-shape as a whole.
[0031] In some embodiments, refer to Figure 3 and Figure 5The hinge 170 is located on the side of the terminal body 110 adjacent to the display screen 120. Specifically, the hinge 170 is located on the side of the main housing 1101 adjacent to the display housing 1201. In some embodiments, there are two hinges 170, arranged at intervals along the length of the main housing 1101, such as... Figure 4 In the embodiment shown, the number of second segments 133 of the connecting portion 130 is two, and the number of second segments 133 corresponds one-to-one with the number of rotating shafts 170, such as... Figure 3 In the embodiment shown, one end of the rotating shaft 170 extends out of the main housing 1101 and is rotatably connected to the second segment 133.
[0032] The connecting part 130 is rotatably connected to the pivot 170, allowing the display screen 120 to be rotatably opened and closed connected to the terminal body 110 via the connecting part 130 and the pivot 170. Specifically, the connecting part 130 is rotatably opened and closed connected to the pivot 170 via a second segment 133, enabling the display screen 120 to rotate and open relative to the terminal body 110, thereby allowing the laptop 100 to switch between a folded state and an unfolded state. In this embodiment, the folded state refers to the stacked state of the main casing 1101 and the display casing 1201; that is, in the folded state, the display surface 1210 of the display module 121 is in contact with the first surface 111 of the main casing 1101. The unfolded state refers to... Figure 1 and Figure 2 The image shows the state of the display housing 1201 when it is rotated to its maximum range relative to the main housing 1101.
[0033] In some embodiments, refer to Figure 3 The circuit board 140 is disposed in the receiving cavity 131 of the connecting part 130. The circuit board 140 is electrically connected to the display screen 120. Specifically, the circuit board 140 is electrically connected to the display module 121 and is used to drive the display screen 120 to display images. When the laptop 100 is in the unfolded state, along the thickness direction of the terminal body 110, the circuit board 140 is located below the side of the terminal body 110 away from the display screen 120. Specifically, the circuit board 140 is located below the second surface 112 of the main body shell 1101 of the terminal body 110, forming a sunken hinge structure of the laptop 100.
[0034] In conventional laptops, the circuit board is located inside the bottom bezel of the display screen. Specifically, when the laptop is unfolded, the circuit board is located on the side of the main body closer to the main body in the thickness direction. This results in a relatively wide bottom bezel of the display screen, making it impossible to achieve a narrow bezel.
[0035] The laptop computer provided in this application embodiment adds a connecting part 130 to the edge of the display screen 120 near the terminal body 110. The first segment 132 of the connecting part 130 is connected to the display part 1200 of the display screen 120, and the second segment 133 is connected to the terminal body 110 through a pivot 170. The circuit board 140 is placed in the receiving cavity 131 of the connecting part 130. When the laptop computer 100 is in the unfolded state, the circuit board 140 is located below the side of the terminal body 110 away from the display screen 120 in its thickness direction, forming a sunken pivot structure. As a result, when the laptop computer 100 is in the unfolded state, along the thickness direction of the terminal body 110, the lower bezel of the display surface 1210 of the display part 1200 near the terminal body 110 can be infinitely close to the first surface 111 of the main body shell 1101 of the terminal body 110, thus achieving an extremely narrow bezel of the display part 1200. Furthermore, because the connection point of the recessed hinge, namely the connection point between the second segment 133 and the hinge 170, is located in the relatively thicker part of the terminal body 110, the display screen 120 of the laptop 100 will not be forced to increase in thickness due to the hinge 170. At the same time, when the recessed hinge is open, the display surface 1210 of the display screen 120 will sink downward along the thickness direction of the terminal body 110, which saves more space from the perspective of space occupation and gives a lighter feeling, thus concealing the visual thickness and the visual narrow bezel, giving a visually thin and light feeling.
[0036] In some embodiments of this application, circuit board 140 is a printed circuit board (PCBA). Circuit board 140 has a narrow design.
[0037] In some embodiments of this application, reference is made to Figure 6 The display panel is disposed in the accommodating cavity 120c. The display shell 1201 has a thickness direction. The display module 121 includes an array substrate 1211 and a color filter substrate 1212 disposed opposite to each other. The array substrate 1211 and the color filter substrate 1212 are disposed opposite to each other along the thickness direction of the display shell. A liquid crystal layer (not shown in the figure) is disposed between the array substrate 1211 and the color filter substrate 1212. The display module 121 is a liquid crystal display module, and the display panel is a liquid crystal display panel. The array substrate 1211 is close to the terminal body 110 in the thickness direction of the display shell 1201, and the color filter substrate 1212 is far away from the terminal body 110 in the thickness direction of the display shell 1201. The circuit board 140 is electrically connected to the array substrate 1211. The array substrate 1211 and the color filter substrate 1212 form an inverted structure along the thickness direction of the display shell 1201, thereby making the display module 121 form an array / CF inverted cell structure.
[0038] In a conventional laptop display module, the color filter substrate is close to the main body of the terminal in the thickness direction of the display shell, while the array substrate 1211 is far away from the main body of the terminal in the thickness direction of the display shell. A protective cover glass needs to be added to the side of the color filter substrate facing the main body of the terminal and attached to the color filter substrate with optical adhesive (OCA) as a protective structure, resulting in a relatively thick display module overall.
[0039] The laptop computer 100 provided in this application embodiment reverses the array substrate 1211 and the color filter substrate 1212 along the thickness direction of the display shell 1201. The array substrate 1211 replaces the protective cover in a conventional laptop computer. The array substrate 1211 overlaps with the display shell 1201, reducing the overall thickness of the display module 121 and saving high-cost materials such as the cover glass and optical adhesive (OCA) at the cell level.
[0040] Additionally, refer to Figure 6 The backlight module 123 is disposed on the outer side of the color filter substrate 1212 away from the array substrate 1211 in the thickness direction of the display shell 1201, and the side of the backlight module 123 away from the color filter substrate 1212 in the thickness direction of the display shell 1201 abuts against the display shell 1201.
[0041] In conventional laptops, the circuit board is located at the bottom bezel of the display. The display features an inverted array / CF cell structure. Although the backlight module is located on the side of the color filter substrate facing away from the array substrate, a metal frame needs to be added inside the display housing to house the backlight module. Furthermore, the circuit board uses a bent structure; that is, the circuit board is located on the side of the metal frame facing away from the color filter substrate, and the circuit board needs to be bent and extended through a flexible printed circuit board (FPC) to connect to the array substrate. This significantly increases the overall thickness of the display, hindering the pursuit of thinner and lighter designs. To address this, existing laptops place the circuit board on the outer side of the display module along its length, achieving a flat circuit. The circuit board no longer needs to be behind the metal frame and can be electrically connected to the array substrate via a flexible printed circuit board (FPC). While this reduces the thickness of the display, it increases the length of the display bezel, making it difficult to achieve a narrow bezel structure.
[0042] The laptop computer 100 provided in this application embodiment refers to... Figure 6By placing the backlight module 123 on the outer side of the color filter substrate 1212 facing away from the array substrate 1211 in the thickness direction of the display shell 1201, and with the side of the backlight module 123 facing away from the color filter substrate 1212 abutting against the display shell 1201 in the thickness direction of the display shell 1201, there is no gap between the backlight module 123 and the display shell 1201. This changes the structural design of the iron frame in conventional laptops, forming a frameless (hinge-up) structural design for the laptop 100. It eliminates the gap between the iron frame and the display shell in conventional laptops, making the backlight module 123 and the display shell 1201 an integrated design. During manufacturing, the display shell 1201 and the backlight module 123 are integrally die-cast, achieving a thinner and lighter display screen 120 in the thickness direction of the display shell 1201.
[0043] In addition, by adding a connecting part 130 to the display section 1200 of the display screen 120, the connecting part 130 extends the display section 1200 and is L-shaped or J-shaped in general. The receiving cavity 131 of the connecting part 130 reserves space for the circuit board 140, forming a sunken hinge structure of the notebook computer 100. This allows the circuit board 140 to not occupy the space of the display section 1200. The circuit board 140 is electrically connected to the array substrate 1211 in a flat state, which covers the problem of the increased bezel of the display shell 1201 caused by the array / CF reversal, the flat design of the circuit board 140 and the removal of the metal frame, thus realizing the narrow bezel design of the display screen. The J-shaped hinge design, while making the backlight thinner and lighter, helps to hide the flexible circuit board and circuit board 140 from a visual perspective, and conceals the defects of the flexible circuit board and circuit board 140 increasing the lower side space of the display shell 1201 in its thickness direction. At the same time, the integrated J-shaped hinge design makes the assembly of the notebook computer 100 more convenient.
[0044] In some embodiments, refer to Figures 1-4 as well as Figure 6 The display housing 1201 includes a front frame 120a (also known as the B housing) and a rear cover 120b (also known as the A housing) covering one side surface of the front frame 120a, as shown in the figure. Figure 6 The front frame 120a and the rear cover 120b together define the accommodating cavity 120c. Specifically, the front frame 120a is square in shape, and the rear cover 120b covers one side surface of the front frame 120a to define the accommodating cavity 120c between the two. The display module 121 and the backlight module 123 are both disposed in the accommodating cavity 120c. The array substrate 1211 is close to the front frame 120a in the thickness direction of the display shell 1201, and the color filter substrate 1212 is close to the rear cover 120b in the thickness direction of the display shell 1201.
[0045] In some embodiments, refer to Figure 6 The front frame 120a of the display housing 1201 is an annular square frame. A mounting groove 122 is provided on the side of the front frame 120a near the display module 121. The mounting groove 122 is annular in shape. The array substrate 1211 in the display module 121 is embedded in the mounting groove 122 to achieve the overlap between the array substrate 1211 and the front frame 120a, and to ensure the stability of the installation between the array substrate 1211 and the front frame 120a.
[0046] In some embodiments, refer to Figure 6 The display module 121 also includes an upper polarizer 1213 and a lower polarizer 1214. The upper polarizer 1213 is stacked on the side of the array substrate 1211 facing away from the color filter substrate 1212 in the thickness direction of the display shell 1201, and the lower polarizer 1214 is stacked on the side of the color filter substrate 1212 facing away from the array substrate 1211 in the thickness direction of the display shell 1201.
[0047] In some embodiments, refer to Figure 6 The backlight module 123 is disposed on the inner surface of the back cover 120b. Specifically, the backlight module 123 includes a first film 1231, a second film 1232, a light guide plate 1233, and a lamp plate 1234 stacked along the thickness direction of the display shell 1201. The lamp plate 1234 abuts against the side of the back cover 120b facing the front frame 120a. The first film 1231 and the color filter substrate 1212 are disposed opposite each other along the thickness direction of the display shell 1201. Both the first film 1231 and the second film 1232 are optical films.
[0048] In some embodiments, the backlight module 123 is a side-emitting backlight module, and the backlight module 123 is selected from one of EL (electroluminescent), LED (light-emitting diode) backlight module and CCFL (cold cathode fluorescent lamp) backlight module. In some embodiments, the backlight module 123 is a CCFL backlight module.
[0049] In some embodiments, refer to Figure 6The rear cover 120b has a support frame 124 protruding from the side of the display shell 1201 facing the front frame 120a in the thickness direction. The support frame 124 includes a first support segment 1241 and a second support segment 1242 connected in sequence. The first support segment 1241 protrudes from the inner surface of the rear cover 120b along the thickness direction of the display shell 1201. The second support segment 1242 extends along the length direction of the display shell 1201 and is parallel to the plane where the display surface 1210 of the display module 121 is located. The second support segment 1242 is connected to the end of the first support segment 1241 away from the rear cover 120b in the thickness direction of the display shell 1201. Specifically, the shape of the first support segment 1241 is... The first support section 1241 is a circular tube, and the second support section 1242 is annular. The second support section 1242 covers the end of the first support section 1241 that is away from the back cover 120b in the thickness direction of the display shell 1201. The first support section 1241 and the second support section 1242 together define a cavity 1243. The backlight module 123 is disposed in the cavity 1243. The lamp plate 1234 of the backlight module 123 abuts against the back cover 120b of the display shell 1201. There is no gap between the lamp plate 1234 and the back cover 120b. The second support section 1242 supports the display module 121 through the support member 125. Specifically, the second support section 1242 supports the color filter substrate 1212 through the support member 125. This allows for the integration of the front frame 120a, back cover 120b, backlight module 123, and display module 121 into the overall design of the laptop 100, resulting in a beautiful, thin, and visually narrow bezel design.
[0050] In some embodiments, refer to Figure 1 , Figure 2 and Figure 6 When the laptop 100 is unfolded, the end where the first segment 132 and the second segment 133 are connected extends to the lower part of the second surface 112 of the main body casing 1101. This allows the laptop 100 to be placed on a horizontal surface, with the end where the first segment 132 and the second segment 133 are connected to the horizontal surface. Furthermore, since the end where the first segment 132 and the second segment 133 are connected extends to the lower part of the second surface 112, it lifts the end where the main body casing 1101 is connected to the second segment 133, creating a gap between the second surface 112 and the horizontal surface. This allows the heat generated by the main body casing 1101 to be dissipated from the second surface 112, improving the performance of the laptop 100.
[0051] In some embodiments, refer to Figure 2When the laptop 100 is unfolded, the angle between the second surface 112 and the horizontal plane is θ1, where 0° < θ1 < 30°. When θ1 is within the above range, a gap exists between the second surface 112 and the horizontal plane to improve heat dissipation, prevent the display shell 1201 from flipping back too much and affecting the viewing experience, and provide a more comfortable input experience for people who work for long periods of time.
[0052] In some embodiments, refer to Figure 2 When the laptop 100 is in its unfolded state, the angle between the first surface 111 of the main casing 1101 and the plane containing the display surface 1210 of the display module 121 is θ2, where 0° ≤ θ2 ≤ 160°. When θ2 is within this range, the display casing 1201 can rotate the connecting part 130 to create a gap between the second surface 112 and the horizontal plane, and this also prevents the display casing 1201 from flipping back too much, which would affect the viewing experience. When θ2 is 0°, the laptop 100 is in a folded state; when θ2 is 160°, the laptop 100 is in an unfolded state (i.e., fully unfolded).
[0053] In some embodiments, refer to Figure 3 The receiving cavity 131 of the connecting part 130 includes a first receiving cavity 1311 and a second receiving cavity 1312. Specifically, the first receiving cavity 1311 is provided in the first segment 132, and the second receiving cavity 1312 is provided in the second segment 133. The first receiving cavity 1311 and the second receiving cavity 1312 are in communication with each other. The circuit board 140 is disposed in the second receiving cavity 1312. (Refer to...) Figure 3 When the laptop 100 is in the unfolded state, the angle between the plane of the circuit board 140 and the plane of the display surface 1210 of the display module 121 is θ3, where 45°≤θ3<160°. When θ3 is within the above range, the stability of the electrical connection between the circuit board 140 and the array substrate 1211 of the display module 121 can be guaranteed.
[0054] In some embodiments, refer to Figure 3 and Figure 6 A flexible circuit board 150 is disposed within the cavity 131. One end of the flexible circuit board 150 is electrically connected to the array substrate 1211 of the display module 121, and the other end of the flexible circuit board 150 is electrically connected to the circuit board 140. Specifically, as follows... Figure 3In the illustrated embodiment, the flexible circuit board 150 is disposed in the first receiving cavity 1311. Since the circuit board 140 is disposed in the second receiving cavity 1312, the end of the flexible circuit board 150 away from the array substrate 1211 of the display module 121 is bent and electrically connected to the circuit board 140, thereby making full use of the space within the receiving cavity 131 and ensuring the stability of the electrical connection between the circuit board 140 and the array substrate 1211 of the display module 121. The bent portion of the flexible circuit board 150 corresponds to the connection point between the first segment 132 and the second segment 133.
[0055] In some embodiments, refer to Figure 3 A mounting member 160 is provided on the inner wall of the second receiving cavity 1312, and the circuit board 140 is fixedly mounted on the inner wall of the second receiving cavity 1312 through the mounting member 160. The design of the mounting member 160 can ensure the installation stability of the circuit board 140 in the second receiving cavity 1312, thereby ensuring the stability of the electrical connection between the circuit board 140 and the array substrate 1211 of the display module 121, and also facilitates the disassembly and maintenance of the circuit board 140.
[0056] In some embodiments, the circuit board 140 is fixedly mounted to the inner wall of the second receiving cavity 1312 using thermal adhesive. The thermal adhesive fixes the circuit board 140 to the inner wall of the second receiving cavity 1312, ensuring the stability of the circuit board 140 within the cavity and also dissipating heat, thus extending its service life.
[0057] In some embodiments, the circuit board 140 and the second segment 133 are integrally formed, thus eliminating the need for components that fix the circuit board 140, thereby reducing the processing and manufacturing cost of the connection portion 130.
[0058] In some embodiments, refer to Figures 1-3 When the laptop 100 is in the unfolded state, the outer surface of the end of the connecting part 130 where the first segment 132 and the second segment 133 are connected can be any of the following shapes: arc-shaped, pointed, and polygonal.
