Description

Technical Field

[0001] This application relates to the field of air conditioning application technology, and in particular to a screen assembly and an air conditioner. Background Technology

[0002] The display module is composed of a matrix of LED beads (light-emitting diodes). The on and off of the LED beads are used to display text, patterns, animations and other effects. The screen switching is achieved by dynamic scanning of the dot matrix. It is usually composed of a modular LED bead matrix module, a control system and a power supply system.

[0003] To improve the display effect, the display module can also be used with other auxiliary lighting components. Generally speaking, because the display module and auxiliary lighting components have different control methods, the air conditioner's display adapter board (used to control various types of peripheral loads of the air conditioner) needs to transmit different display signals to the display module and auxiliary lighting components respectively. This is not conducive to the linkage between the display module and auxiliary lighting components and relies entirely on the control accuracy of the display adapter board. Utility Model Content

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various implementations. Simultaneously, the steps or actions described in the method description can be rearranged or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various orders in the specification and drawings are merely for the clear description of a particular embodiment and do not imply a mandatory order, unless otherwise stated that a particular order must be followed.

[0027] In the description of this application, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0028] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0029] In existing technologies, two different display components typically require different control modules. If it's necessary to control the two display components to display in tandem, a main control chip is needed to send control signals to both control modules separately, making the two display components appear to be displaying in tandem. This requires the main control chip to correctly determine the current tandem display mode and send the correct two control signals at the correct time, placing high demands on control precision and logic. In air conditioners, as air conditioners become increasingly feature-rich, the peripheral load connected to the display adapter board also increases, including displays, radar modules, voice modules, camera modules, etc. The control logic of the display adapter board becomes increasingly complex. Controlling the tandem display of two display components under these conditions significantly increases the difficulty of control and easily leads to asynchronous display issues.

[0030] Based on this, this application provides a screen assembly and an air conditioner. The screen assembly includes a display module and an auxiliary lighting assembly. The display module includes a matrix of display units, a display driving circuit, and a main control chip. The auxiliary lighting assembly includes a lighting driving circuit. The main control chip is connected to the display adapter board of the air conditioner to receive display signals sent by the display adapter board. It is also connected to the display driving circuit and the lighting driving circuit. The main control chip controls the display content of the display module and the auxiliary lighting assembly according to the display signals. In the above solution, the auxiliary lighting assembly does not directly receive the display signals from the display adapter board. During operation, the display adapter board only needs to connect to the display module. The main control chip determines the display of both the display module and the auxiliary lighting assembly, which simplifies the connection method between various electronic control boards and facilitates the linkage between the display module and the auxiliary lighting assembly controlled by the main control chip.

Figure 2 As shown, Figure 2 This is a front structural diagram of the display component provided in an embodiment of this application, with reference to... Figure 3 As shown, Figure 3 This is a schematic diagram of the rear structure of the display component provided in an embodiment of this application. The screen component provided in this embodiment is disposed on the front panel 400 of an air conditioner, and the screen component includes:

[0032] The display module 100 includes a matrix of display units, a display driving circuit, and a main control chip. The display driving circuit is electrically connected to the display units of the display module 100, and the main control chip is electrically connected to the display driving circuit and is used to output a first driving signal to the display driving circuit. The main control chip is also electrically connected to the display adapter board of the air conditioner to receive the display signal from the display adapter board.

[0033] The auxiliary lighting assembly 200 includes a lighting driving circuit, which is electrically connected to the light-emitting element of the auxiliary lighting assembly 200. The main control chip is also electrically connected to the lighting driving circuit and is used to output a second driving signal to the lighting driving circuit.

[0034] The screen assembly comprises two parts: a display module 100 and an auxiliary lighting assembly 200. The display module 100 has a matrix composed of multiple display units. A display driving circuit drives the display units at different positions in the matrix to emit light. A main control chip is used to interface with the display adapter board for signal exchange. During operation, the main control chip receives display signals from the display adapter board and then controls the display driving circuit to operate based on these signals. (Refer to...) Figure 4As shown, to simplify the connection between the screen assembly and the display adapter board, the control of the auxiliary lighting assembly 200 is handled by the main control chip of the display module 100. The main control chip controls the operation of the display driving circuit based on the display signal, and also controls the operation of the lighting driving circuit of the auxiliary lighting assembly 200. This is suitable for scenarios where the display content of the auxiliary lighting assembly 200 and the display module 100 are linked. For example, the air conditioner's display adapter board sends a display signal indicating that the indoor temperature is 25°C in real-time during cooling mode to the screen assembly. The screen assembly controls the display units of the display module 100 to display the words "25°C" and controls the auxiliary lighting assembly 200 to emit a cool color. Alternatively, the air conditioner's display adapter board sends a display signal indicating the intelligent fan mode during heating mode to the screen assembly. The screen assembly controls the display units of the display module 100 to display a fan pattern that rotates over time and controls the auxiliary lighting assembly 200 to emit a warm color. In this way, the auxiliary lighting component 200 does not directly receive the display signal from the display adapter board. When working, the display adapter board only needs to connect to the display module 100. The main control chip of the display module 100 determines the display of both the display module 100 and the auxiliary lighting component 200. There is only one connection line between the screen component and the display adapter board, which simplifies the connection method and realizes the linkage display control of the two display components. The display adapter board does not need to take into account how the two display components display synchronously, thus reducing the complexity of the control logic of the display adapter board.

[0035] The display module 100 can be an LED dot matrix screen, and the display unit can be an LED bead in the LED dot matrix screen. Multiple LED beads are combined to form an LED bead matrix to display different patterns. The display module 100 can also be other types of display screens, such as a display surface composed of multiple small screens spliced ​​together, in which case the display unit is a small screen. There are no restrictions on the matrix arrangement of the display units in the display module 100.

[0036] In some embodiments, the display module 100 includes a first cable 110 and a second cable 120. The main control chip is connected to the display adapter board of the air conditioner through the first cable 110, the main control chip is connected to the display driving circuit through internal wiring, and the main control chip is connected to the light driving circuit through the second cable 120.

[0037] The display module 100 integrates a main control chip, and the main control chip sends wires to the display adapter board and auxiliary lighting assembly 200 of the air conditioner, thereby reducing wiring complexity. The display module 100 itself has a control board, which integrates the main control chip. Therefore, the main control chip can be connected to the display driver circuit through internal wiring within the control board, while the first cable 110 and the second cable 120 are connected externally through wiring ports. (Refer to...) Figure 3As shown, the first cable 110 connects to the display adapter board of the air conditioner, and the second cable 120 connects to the light driving circuit of the auxiliary light assembly 200. Depending on actual needs, the wire groups of the first cable 110 and the second cable 120 can be the same or different; for example, the first cable 110 can be a cable suitable for 12V serial communication, and the second cable 120 can be a cable suitable for I2C communication.

[0038] In some embodiments, the screen assembly includes a housing 300, which includes a first receiving portion 310. The first receiving portion 310 has a first cable outlet 311. The display module 100 is disposed in the first receiving portion 310, and a first cable 110 and a second cable 120 exit from the first cable outlet 311. The housing 300 also includes a second receiving portion 320, which has a second cable outlet 321. An auxiliary lighting assembly 200 is disposed in the second receiving portion 320, and the second cable 120 is connected to the auxiliary lighting assembly 200 through the second cable outlet 321.

[0039] The display module 100 is installed as a whole in the first receiving portion 310 of the housing 300 of the screen assembly. To facilitate cable connection and exit, a first cable exit port 311 is provided on the edge of the first receiving portion 310. The size of the first cable exit port 311 is set according to the wire diameter of the first cable 110 and the second cable 120. Similarly, the auxiliary lighting assembly 200 is installed as a whole in the second receiving portion 320 of the housing 300 of the screen assembly. To facilitate cable connection and exit, a second cable exit port 321 is provided on the edge of the second receiving portion 320. The size of the second cable exit port 321 is set according to the wire diameter of the second cable 120.

[0040] according to Figure 3 The housing 300 shown has the aforementioned first cable outlet 311 and second cable outlet 321 on its back side. The display module 100 is rectangular, and the first receiving portion 310 is also rectangular. The first cable outlet 311 is opened on the edge of the rectangle, and a first cable management portion 130 is provided on the back side of the housing 300. The first cable 110 is led out of the first cable outlet 311 and then runs through the first cable management portion 130 to the display adapter board. A second cable management portion 140 is also provided on the back side of the housing 300. The second cable 120 is led out of the first cable outlet 311 and then runs through the second cable management portion 140 to the second cable outlet 321. The auxiliary light assembly 200 is annular, and the second receiving portion 320 is also annular. The second cable outlet 321 is opened at one point of the annulus. In order to reduce the cable length, the second cable outlet 321 and the first cable outlet 311 are close together, and the second cable management portion 140 is provided between them.

[0041] In some embodiments, the auxiliary lighting component 200 is an ambient light, and the light-emitting element of the auxiliary lighting component 200 is an LED bead. The LED beads of the ambient light are arranged around the display module 100. In this embodiment, the auxiliary lighting component 200 is composed of multiple LED beads, which can be multi-color LED beads to provide different color effects. Furthermore, these LED beads are arranged to surround the display module 100 to improve the visual appeal of the front panel 400 of the air conditioner.

[0042] To enable ambient lighting to display various effects, the arrangement of multi-color LED beads differs from the traditional direct series LED solution. Ambient lighting comprises multiple LED beads with built-in RGB chips, cascaded together. For example, an ambient light can use 36 cascaded RGB LEDs with built-in chips, with input and output signals sequentially transmitted to control the synchronized lighting effects. Compared to conventional driver chips controlling LED on / off states, this method allows individual control of each LED's on / off state and RGB color, optimizing LED control efficiency, improving response speed, and efficiently and smoothly presenting different dynamic lighting effects. It can also interact with the air conditioner's operating mode. For example, cooling is indicated by a constant blue light, heating by a constant orange light, and the air conditioner's AI function by a pink running light effect.

[0043] In some embodiments, the display module 100 further includes a first display area 150 and a second display area 160. The display driving circuit includes a first driving module and a second driving module. The first driving module is connected to the display unit of the first display area 150, and the second driving module is connected to the display unit of the second display area 160. The first driving module is used to drive the display unit of the first display area 150 to periodically update its light-emitting state, and the second driving module is used to drive the display unit of the second display area 160 to light up or turn off simultaneously.

[0044] In actual use, the display module 100 may need to display various contents. Some contents need to be dynamically updated, such as temperature values ​​and fan rotation patterns, while others do not need to be dynamically updated, such as WiFi icons and voice icons, which are always on or always off. Taking the display module 100 as an LED dot matrix screen as an example, for a whole module of the display module 100, the screen switching is achieved through dynamic scanning of the dot matrix. When switching screens, the entire LED matrix is ​​directly scanned and refreshed, making it impossible to directly display dynamically changing content and static fixed content simultaneously. To solve the above problem, the display module 100 is divided into a first display area 150 and a second display area 160, as shown in the figure. Figure 2 As shown, the first display area 150 is a dynamically updated display area, and the second display area 160 is a statically fixed display area. A first driving module and a second driving module are configured for each of the two areas respectively. (Refer to...) Figure 5As shown, in actual operation, the first driving module can periodically update the driving level of the LED beads in the first display area 150 to achieve dynamic display, while the second driving module only needs to maintain the driving level of the LED beads in the second display area 160 to achieve constant on and constant off.

[0045] As can be seen from the above-described partition control, the LEDs in the first display area 150 typically exhibit both on and off states simultaneously, while the LEDs in the second display area 160 will only either be on or off simultaneously. Therefore, the arrangement of the LEDs in the second display area 160 can be set according to the shape of the icon to be displayed. For example, if the icon to be displayed is a WiFi icon, then the arrangement of the LEDs should be set according to the WiFi icon. It is understood that there can be more than one second display area 160, for example, refer to... Figure 2 As shown, two secondary display areas 160, one for WiFi and one for voice, are set in the upper right corner of the display module 100.

[0046] In some embodiments, the display module 100 further includes a control board, which carries a display driving circuit and a main control chip. The control board includes metal vias, which correspond to at least one chip pin in the first driving module and / or the second driving module.

[0047] The display module 100 typically has a large number of display units, and corresponding driver chips are set according to the number of display units. The display driver circuit may include multiple driver chips, which are connected to the main control chip. Therefore, the control board of the display module 100 carries a large number of chips. In addition, the space of the front panel 400 of the air conditioner is not large, and the design integration of the display module 100 is relatively high, which places certain requirements on the heat dissipation capacity of the control board. In this embodiment, the control board adopts a multi-layer board, and metal vias are used to assist in the heat dissipation of each chip. That is, vias are added to the pads on the bottom of the chips for heat conduction, so as to prevent the chips from overheating and burning out, which would cause the display units to fail to light up and form dead pixels.

[0048] In summary, the screen assembly includes a display module 100 and an auxiliary lighting assembly 200. The display module 100 includes a matrix of display units, a display driving circuit, and a main control chip. The auxiliary lighting assembly 200 includes a lighting driving circuit. The main control chip connects to the display adapter board of the air conditioner to receive display signals sent by the display adapter board. It also connects to the display driving circuit and the lighting driving circuit, controlling the display content of the display module 100 and the auxiliary lighting assembly 200 according to the display signals. In the above scheme, the auxiliary lighting assembly 200 does not directly receive display signals from the display adapter board. During operation, the display adapter board only needs to connect to the display module 100. The main control chip of the display module 100 determines the display of both the display module 100 and the auxiliary lighting assembly 200, simplifying the connection between the various electronic control boards and facilitating the linkage between the display module 100 and the auxiliary lighting assembly 200 controlled by the main control chip of the display module 100.

[0049] This application also provides an air conditioner, including a screen assembly of any of the above embodiments. The screen assembly is disposed on the front panel 400 of the air conditioner and can be embedded behind the front panel 400 of the air conditioner. A light-transmitting protective layer is provided on the front of the front panel 400 of the air conditioner to protect the screen assembly.

[0050] The screen component of this application will be described in detail below with a specific example.

[0051] The screen components include an LED dot matrix display and ambient lighting. The LED dot matrix display uses direct LED drive to create dynamic and variable animations based on different air conditioner modes, while the ambient lighting also changes its lighting effects in sync. This solution integrates the LED dot matrix display and ambient lighting into a single structure. The driving signal for the ambient lighting is provided by the main control chip on the PCB board of the LED dot matrix display, and then converted to 5V input via a level conversion chip to control the lighting effects of the ambient lighting. Since the display logic of the ambient lighting is controlled by the main control chip of the LED dot matrix display, the electrical control architecture is also integrated, simplifying the information transmission process between boards, improving chip operating efficiency, and facilitating the coordinated control output of the LED dot matrix display and ambient lighting effects.

[0052] The LED dot matrix screen and ambient light are each a complete display component. During actual assembly, the LED dot matrix screen's PCB leads out with wires. The wire group is split into two, with one end connected to the ambient light and the other end connected to the display adapter board via an adapter board. The connection points between the wire outlet holes and the terminals are glued to secure them, preventing the terminals from falling off or making poor contact due to force during insertion.

[0053] The LED dot matrix screen has a resolution of 26*32 (other resolutions such as 26*39 can also be used), and the spacing between adjacent LEDs is 2.5mm (it can also be 2mm or 1.5mm, etc.). Excluding the LEDs for the fixed icons in the upper right corner, the actual number of LEDs is 796 (the WIFI and voice icons in the upper right corner are illuminated separately). Lighting up so many LEDs requires 16 driver chips. The PCB board also includes a 12V to 5V DC-DC converter, a 5V to 3.3V LDO converter, a 3.3V to 5V level conversion circuit, peripheral circuits for the main control chip, and Flash circuitry. Therefore, a 4-layer PCB layout is required. To further save circuit layout space and control the minimum via pad size, multiple parallel vias are used in the same location / network when routing space allows.

[0054] To improve power supply filtering performance, decoupling capacitors are placed as close as possible to each chip at the power input, and bypass capacitors are placed close to the power input. Due to the large number of LEDs, and considering the need to meet the heat dissipation requirements of LEDs during long-term operation, sufficient copper foil is reserved at the bottom of each chip for heat dissipation, and vias are added to the pads on the bottom of the chips for heat conduction to prevent the chips from overheating and burning out, which would cause the LEDs to fail to light up and become dead pixels.
