[0002] At present, most display products on the market, including monitors, electronic signs, and TVs, are designed with remote control receiving modules and key modules to control product functions. The remote control receiving module is usually installed in or under the face frame, and the key module is usually installed under, on the side or at the back of the rear shell. With the expansion of demand for display products in outdoor, commercial and retail industries, the original traditional design can no longer meet customers' appearance requirements, and some customers no longer need remote control modules and key modules. However, some of the functions they cover still need to be retained, such as brightness adjustment, volume adjustment and other functions.

This design is more beautiful. The application scenarios and environments of this type of display signage products are relatively wide and messy. Customers have different requirements for brightness and volume, and the corresponding adjustment devices cannot achieve 360-degree multi-angle placement, which makes it impossible for end customers to flexibly adjust the basic volume and backlight functions, and at the same time leads to the inability to meet the different needs of different scenarios.

[0036] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The methods described in the following exemplary embodiments do not represent all methods consistent with the present application. Instead, they are merely examples of devices consistent with some aspects of the present application as detailed in the appended claims.

[0037] A display device includes a housing 10, a circuit board component 20, and a potentiometer assembly. The circuit board component 20 is located in the housing 10 and connected to the housing 10. The potentiometer assembly includes a resistor 30 and an adjustment portion, wherein the resistor 30 is disposed on the circuit board component 20 and is electrically connected to the circuit board component 20. One end of the adjustment portion abuts against a side of the resistor 30 away from the circuit board component 20, and an adjustment hole 60 is provided on the housing 10, through which the other end of the adjustment portion extends out of the housing 10.

[0038] Reference Figure 1-2 The resistor 30 and the adjustment part are located between the circuit board component 20 and the housing 10. The resistor 30 is fixed in the housing 10 by connecting the circuit board component 20 with the housing 10. An adjustment hole 60 is provided on the side of the housing 10 close to the operating part, so that the adjustment part can partially extend out of the housing 10 through the adjustment hole 60. The part extending out of the housing 10 can facilitate the end customer to directly apply external force to it, drive the operating part to slide on the resistor 30, change the resistance value of the resistor 30, and then change the current or voltage in the circuit of the display device to adjust the volume, brightness and other parameters of the display device.

[0039] In actual application, due to the wide range of application scenarios and environments of commercial retail display signs without remote control and buttons, different customers have different requirements for the volume and brightness of the display device. In addition, when displaying the display device, the display device needs to be placed at 360° multiple angles. The traditional remote control and button adjustment method greatly increases the adjustment difficulty for end customers.

[0040] The present application can change the position of the adjustment hole 60 to meet the placement of different display devices at multiple angles and in multiple complex terrains during actual application, so as to adapt to different application scenarios and meet different customer needs. Secondly, due to the exposure of the operating part, the end user can simply adjust the volume or brightness of the display device by pushing the operating part, which greatly reduces the adjustment time and improves the customer's experience. Finally, customer products such as commercial retail display signs without remote control and buttons tend to be four-sided designs. A layer of tempered glass is attached to the face frame of the display device, and the back shell uses a small rectangular backpack or an integrated all-inclusive metal back shell. The present application does not need to make a remote control receiver inlay on the face frame of the display device, and the back shell does not need to reserve button holes, so that the appearance of the display device can achieve a true four-sided design, which can improve the aesthetics of the product while also flexibly adjusting the volume and brightness of the display device.

[0041] Furthermore, according to the product application scenario and customer needs, the size and opening position of the adjustment hole 60 are determined at the beginning of the design of the shell 10 of the display device, and the displacement hole is processed when the shell 10 is opened, and the circuit board component 20 can be installed according to the position of the displacement hole. This setting can reduce the installation time of the display device and improve the production efficiency of the display device.

[0042] In some embodiments, the length of the adjustment hole 60 in the first direction X is less than or equal to the length of the resistor 30 in the first direction X.

[0043] The adjustment hole 60 is used to accommodate the displacement of the adjustment part in the first direction X, and the displacement range of the adjustment part only needs to be within the adjustment range of the resistor 30 to adjust the resistance value. This arrangement can ensure that the size of the adjustment range corresponds to the size of the required adjustment hole 60. While achieving the resistance value adjustment, it can also avoid the pollution of the display device by the external environment caused by the excessive size of the adjustment hole 60.

[0044] In some embodiments, the adjustment portion includes a sliding member 50 and an operating member, the sliding member 50 is in contact with the resistor 30, and the operating member partially extends out of the adjustment hole 60. When the operating member is subjected to an external force, it can drive the sliding member 50 to move in the first direction X of the resistor 30 to adjust the resistance value.

[0045] In this embodiment, the contact point between the sliding member 50 and the resistor 30 is a moving contact. The moving contact contacts and slides on the resistor 30, and the surface of the resistor 30 has a low resistivity, so that the contact resistance between it and the moving contact is correspondingly small. At the same time, the surface resistivity is evenly distributed, which can ensure that the contact resistance change and the track resistance change are small within the effective electrical stroke, thereby obtaining an ideal resistance regularity characteristic.

[0046] Furthermore, in actual applications, the display device needs to adjust the volume, brightness and other parameters many times, which requires the sliding member 50 and the resistor 30 to rub back and forth. Therefore, in the present application, the surface of the resistor 30 has appropriate smoothness, hardness and wear resistance, so as to improve the durability of the adjustment part and the resistor 30, reduce the frequency of maintenance or repair, and reduce the cost of use.

[0047] In some embodiments, reference Figure 4-5 The sliding member 50 includes a first sliding arm 501 and a second sliding arm 502. The first sliding arm 501 and the second sliding arm 502 are both arc-shaped. The first sliding arm 501 and the second sliding arm 502 are connected to form a semicircle. The operating member is located at the connection between the first sliding arm 501 and the second sliding arm 502. The diameter of the semicircle is greater than the diameter of the adjustment hole 60.

[0048] Specifically, a carbon film region and a copper skin region are provided on the surface of the resistor 30. The first sliding arm 501 contacts the carbon film region, and the second sliding arm 502 contacts the copper skin region.

[0049] In this embodiment, continue to refer to Figure 4-5 The first sliding arm 501 and the second sliding arm 502 are connected to form a semicircle, which can be understood as an arch. The arch-shaped sliding member 50 is located in the housing 10, and the operating member located at the connection between the first sliding arm 501 and the second sliding arm 502 extends out of the housing 10 through the displacement hole. The diameter of the semicircle formed by the first sliding arm 501 and the second sliding arm 502 in the present application is larger than the diameter of the displacement hole, which can ensure that the sliding member 50 will not fall off outside the housing 10. In this way, the stability of the device is ensured.

[0050] In some embodiments, the adjusting portion further includes a protective member, which is mounted on an end of the operating member extending out of the housing 10 .

[0051] The setting of the protective member can not only ensure that the operating member is not damaged and reduce the replacement frequency of the operating member, but also help the customer to adjust the display device and improve the user experience.

[0052] In this embodiment, the operating member can be configured as a paddle, a slider, or a round handle. The protective member and the operating member can be connected by plugging, snapping, socketing, welding, or other connection methods.

[0053] Preferably, refer to Figure 5 , the operating part uses a sliding paddle 40, refer to Figure 6-7 The protective member is configured as a sliding cover cap 70. The sliding cover cap 70 is snap-connected to the sliding paddle 40.

[0054] In some embodiments, a first connection portion is disposed on the housing 10 , and a second connection portion is disposed on the circuit board component 20 . The first connection portion cooperates with the second connection portion to fix the resistor 30 in the housing 10 .

[0055] The cooperation of the first connection part and the second connection part can fix the circuit board component 20 and the resistor 30 on the circuit board component 20 in the housing 10. This movable connection method can change the position of the potentiometer assembly according to the position of the displacement hole. This can meet the placement of different display devices in multiple angles and complex terrains during actual application, adapt to different application scenarios and meet different customer needs. That is, no matter how the display device is placed, the position can be changed by disassembling the potentiometer assembly for adjustment by the end customer.

[0056] In some embodiments, adjacent first connection parts and adjacent second connection parts are arranged at intervals along the first direction X, the adjustment hole 60 is located between adjacent first connection parts, and the resistor body 30 is located between adjacent second connection parts. The length of the adjustment hole 60 in the first direction X is less than the spacing between adjacent first connection parts, and the length of the resistor body 30 in the first direction X is less than the spacing between adjacent second connection parts.

[0057] Reference Figure 1 The length of the adjustment hole 60 in the first direction X is smaller than the spacing between adjacent first connecting parts, and the length of the resistor 30 in the first direction X is smaller than the spacing between adjacent second connecting parts. The connection position of the first connecting part and the second connecting part can play a certain limiting role, ensuring the correspondence between the resistor 30 and the strip hole, and then ensuring that the operating part extends out of the displacement hole to achieve adjustment.

[0058] In some embodiments, one of the first connection portion and the second connection portion is configured as a protrusion, and the other is configured as a groove, and the protrusion is located in the groove. Figure 1 The first connection portion is configured as a rivet column 101, referring to Figure 3 , the second connection portion is configured as a threaded hole 201.

[0059] Reference Figure 1 , rivet posts 101 are arranged on the housing 10, threaded holes 201 are opened on the circuit board 20, and the spacing between the rivet posts 101 is consistent with the spacing between the threaded holes 201. The circuit board is fixed in the housing 10 by threading the rivet posts 101 and the threaded holes 201.

[0060] Furthermore, the rivet stud 101 can be reserved when the shell 10 is opened according to the product application scenario and customer needs. The circuit board component 20 can be installed according to the position of the rivet stud 101. This setting can reduce the installation time of the display device and improve the production efficiency of the display device.

[0061] It should be noted that the rivet stud 101 and the displacement hole can be processed simultaneously when the housing 10 is opened, or the position of the rivet stud 101 can be processed first, and the position of the displacement hole can be processed later according to the size of the paired resistor 30. Alternatively, the position of the displacement hole can be processed first, and the rivet stud 101 can be welded, clamped or plugged into the housing 10 according to the position of the threaded hole 201 on the circuit board component 20.

[0062] In some embodiments, the processing position of the rivet stud 101 can be set on the back side of the housing 10, or on any one of the four sides of the display device.

[0063] In some embodiments, the resistor 30 is configured as one of a wirewound potentiometer, a membrane potentiometer, and a synthetic solid core potentiometer.

[0064] The wirewound potentiometer is a resistor body 30 made by winding a resistor wire around a frame to form a circular ring or spiral shape. The membrane potentiometer includes a thin film potentiometer or a thick film potentiometer, which is a resistor film formed on a public substrate, and the shape is mostly horseshoe-shaped, arc-shaped or long strip. The synthetic solid core potentiometer is a horseshoe-shaped or long strip resistor track molded on a base. The above-mentioned resistor body 30 and its application are common knowledge in the field, and no further elaboration is made.

[0065] It should be specially noted that the potentiometer assembly in the present application can be understood as a straight-sliding limiter.

[0066] In some embodiments, the shape of the adjustment hole 60 is configured as a rectangle or a shape with two ends of the rectangle being semicircles.

[0067] With the development of technology, users prefer to choose thinner display devices. In order to meet the adjustment function of the display device, displacement holes need to be opened around or on the back of the display device to adjust the resistance value, thereby achieving the adjustment of the parameters such as sound and brightness of the display device.

[0068] In this embodiment, refer to Figure 6-7 The adjustment hole 60 is preferably a strip hole with a longer length and a shorter width, or a rectangular hole, which can not only meet the adjustment requirements of the adjustment part (ie, the position requirements of moving back and forth in the first direction X), but also adapt to the size requirements of the display device.

[0069] In some embodiments, reference Figure 1-2 A connector 80 is provided on one side of the circuit board component 20 away from the resistor 30 , and the connector 80 is connected to different ports of the power supply mainboard to adjust the volume and backlight of the display device.

[0070] The following embodiment describes a process for adjusting the brightness of a display device.

[0071] It should be noted that display backlight adjustment products are mainly divided into adjustable (ADJ) DC dimming and pulse width modulation (PWM) AC dimming. The potentiometer can be the wirewound potentiometer, membrane potentiometer, synthetic solid potentiometer and the direct slide potentiometer described in this article.

[0072] In this embodiment, the combination of ADJ DC dimming and a direct-slide potentiometer is used as an example for illustration.

[0073] The connector 80 may preferably be a terminal block. The three pins on the terminal block are connected to the three pins on the circuit board 20, namely VCC (positive circuit voltage) / GND (ground wire) / OUT (output terminal), and then connected to the 5V (or 3.3V) / GND / ADJ of the product power board through wires for regulation and control.

[0074] When the direct-slide potentiometer is powered on, a voltage drop (understood as a voltage difference) is generated between the OUT pin of the direct-slide potentiometer and GND (ground wire). This voltage drop changes with the position of the sliding member 50 (the first sliding arm 501 and the second sliding arm 502). The output voltage value is the ratio of the resistance value at the current position to the total resistance value of the entire direct-slide potentiometer.

[0075] After the ADJ pin of the power board receives the voltage output by the potentiometer OUT pin, it adjusts the backlight. When the voltage is 0, the backlight output is the lowest, and when the voltage is 5V (3.3V), the backlight output is the highest. During the entire sliding process, the voltage and the backlight current output are linearly related. (The principle of this software is roughly the same as the brightness control of the menu of our conventional monitor or TV product remote control). Similarly, this application can also be used for volume adjustment.
