Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a display module, a display device and an electrical appliance with a touch function. Background Art

[0002] Display screens with touch functions are becoming more and more widely used because they can not only display information but also receive user input, thereby realizing interaction between users and home appliances.

[0003] In order to provide a better interactive experience, the area of ​​the display screen that can be touched is getting larger and larger, such as reaching 5 square centimeters.

[0004] In the related technical solutions, the solution for realizing touch control of the above-mentioned display screen is mainly to stick an ITO (ITO is an N-type oxide semiconductor - indium tin oxide) touch film on the TFT (Thin Film Transistor) display screen or behind the color film and then stick it to the cover plate, and realize the color display effect with touch control by illuminating the bottom with an LED (light-emitting diode).

[0005] However, in the above solution, the cost of realizing touch control on the display screen is relatively high, and the ITO (ITO is an N-type oxide semiconductor - indium tin oxide) touch film has poor bending resistance and is prone to failure. At the same time, the plug-in end of the ITO touch film is easily affected by high-temperature water vapor, vibration, etc., resulting in poor contact. Summary of the invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0007] To this end, a first aspect of the present invention is to provide a display module with a touch function.

[0008] A second aspect of the present invention provides a display device.

[0009] A third aspect of the present invention provides an electrical appliance.

[0010] In view of this, according to a first aspect of the present invention, the present invention provides a display module with a touch function, comprising: a circuit board; a pattern layer, arranged opposite to the circuit board, and having a pattern on the pattern layer; a light-emitting diode with a touch function, located between the circuit board and the pattern layer, and arranged on the circuit board; wherein the light-emitting diode with a touch function adjusts light-emitting parameters and switches the display state of the pattern according to the user's touch input.

[0011] In this technical solution, a display module with a touch function is proposed, which can realize the touch input of the user while realizing the display of the pattern. In this process, since a light-emitting diode with a touch function is used to realize the touch function, there is no need to stick an ITO touch film, so the problem that the display module is prone to failure due to the poor bending resistance of the ITO (ITO is an N-type oxide semiconductor-indium tin oxide) touch film in the related technical solution can be overcome.

[0012] In addition, since there is no need to stick an ITO touch film, the problem of poor contact caused by the plug-in end of the ITO touch film being easily affected by high temperature water vapor, vibration, etc. is avoided, thereby improving the reliability of the display module. At the same time, the display module with touch function proposed by the present invention can be applied to different working conditions.

[0013] In some technical solutions, optionally, a light-emitting diode with touch function can be understood as a light-emitting diode that can input according to the user's touch input, that is, it can receive the user's touch input to the display module and output a corresponding signal to achieve interaction between the display module and the user.

[0014] In addition, the light emitting diode with touch function not only realizes the touch function, but also has the function of a light emitting diode, that is, it can emit light, and the pattern in the pattern layer can be illuminated by the light emitted by the light emitting diode, thereby realizing the display of the pattern.

[0015] In one of the technical solutions, the luminous parameters include one or more of whether to emit light, the color of the light, and the intensity of the light.

[0016] In addition, the display module with touch function proposed in this application also has the following additional technical features.

[0017] In some technical solutions, optionally, the light-emitting diode with touch function has a touch electrode terminal and a light-emitting diode terminal, and the light-emitting diode with touch function is welded on the circuit board through the touch electrode terminal and the light-emitting diode terminal; wherein the touch electrode terminal is used to output the sensing amount corresponding to the touch input, and the light-emitting diode terminal is used to input the signal for adjusting the light-emitting parameters.

[0018] In this technical solution, the light-emitting diode with touch function has a touch electrode terminal, wherein, when the light-emitting diode with touch function receives the user's touch input, it can output the sensing amount corresponding to the touch input through the touch electrode terminal, so that the controller connected to the light-emitting diode with touch function can obtain the sensing amount corresponding to the touch input, thereby realizing the recognition of the touch input.

[0019] The light emitting diode with touch function has a light emitting diode connection terminal, so that the light emitting diode can be controlled by the light emitting diode connection terminal, thereby realizing the switching of the display state of the pattern.

[0020] In some technical solutions, optionally, it also includes: a light uniforming sheet located between the light-emitting diode with touch function and the pattern layer.

[0021] In this technical solution, the light emitted by the light-emitting diode with touch function is prone to divergence. When the above problem exists, after the pattern in the pattern layer is illuminated by light, the brightness of different positions in the pattern is likely to be inconsistent, and the existence of the above situation affects the display effect of the display module.

[0022] In the technical solution of the present application, a light homogenizer is provided so as to utilize the light homogenizer to process the light emitted by the light emitting diode with a touch function, so that the light irradiating the pattern in the pattern layer is more uniform, thereby improving the display effect of the display module.

[0023] In some technical solutions, optionally, the light homogenizer may be frosted glass.

[0024] In some technical solutions, optionally, the light-homogenizing sheet is a light-homogenizing coating printed on the pattern layer.

[0025] In this technical solution, the light-homogenizing sheet is a light-homogenizing coating printed on the pattern layer. When preparing a display module, the light-homogenizing sheet can be directly prepared on the basis of the pattern layer by spraying or electroplating. In this process, the pattern layer and the light-homogenizing sheet can be integrated into one design, which can reduce the assembly difficulty of the display module while ensuring the display effect of the display module and improve the yield rate of the display module.

[0026] In addition, the thickness of the uniform light coating can be determined according to actual design requirements, which will not be elaborated here.

[0027] In some technical solutions, optionally, it also includes: a display bracket, which is arranged between the circuit board and the light homogenizer, and the display bracket, the circuit board and the light homogenizer are surrounded by a cavity, and the light-emitting diode with touch function is located in the cavity.

[0028] In this embodiment, the light-emitting diode with touch function is arranged in the cavity, so that after the display module is manufactured, the cavity can be used to protect the light-emitting diode with touch function, thereby reducing the probability of damage to the light-emitting diode with touch function due to high temperature water vapor, vibration and other factors, thereby ensuring the reliability of the display module.

[0029] In addition, the setting of the display bracket can connect the circuit board with the light homogenizer, thereby ensuring the firmness of the display module, improving the display module's ability to cope with harsh working conditions, and ensuring the reliability of the display module.

[0030] In some technical solutions, optionally, the display bracket is a non-light-transmissive bracket.

[0031] In this technical solution, by selecting a non-light-transmitting display bracket, the display bracket can be used to limit the light emission direction of the light-emitting diode with touch function located in the cavity. While improving the display brightness of the pattern illuminated by it, it can also reduce the interference of light on adjacent display modules, that is, reduce the probability of cross-talk and ensure the display effect of the display module.

[0032] In some technical solutions, optionally, a side of the display bracket located in the cavity is sprayed with a non-light-transmissive coating.

[0033] In some technical solutions, optionally, the display bracket is made of a non-light-transmissive material.

[0034] In some technical solutions, optionally, it also includes: a cover plate, which is bonded to the pattern layer and located on a side away from the circuit board.

[0035] In this technical solution, a cover plate is provided to protect the pattern layer, the light-homogenizing sheet, and the light-emitting diode with a touch function, thereby improving the display module's ability to cope with harsh working conditions and ensuring the reliability of the display module.

[0036] In some technical solutions, optionally, the cover plate is a glass cover plate or an acrylic cover plate.

[0037] In some technical solutions, optionally, the pattern layer is a coating printed on the cover plate.

[0038] In this technical solution, by limiting the pattern layer to a coating printed on the cover plate, the pattern layer and the cover plate can be integrated, thereby reducing the number of components required during the assembly of the display module. While reducing the difficulty of assembly, it also improves assembly efficiency and assembly yield, thereby reducing the manufacturing cost of the display module.

[0039] In some technical solutions, optionally, the light homogenizing sheet and the pattern layer are coatings sprayed on the cover plate in sequence.

[0040] According to the second aspect of the present invention, the present invention provides a display device, comprising: M display windows, M is a positive integer greater than or equal to 1; N display modules with touch functions of any one of the above items, corresponding to the M display windows, N is a positive integer greater than or equal to 1; a controller, connected to the N display modules, for controlling the display state of each display window in the M display windows.

[0041] In this technical solution, a display device is proposed, in which the display device includes a display module with a touch function as described above. Therefore, all the beneficial effects of the display module with a touch function as described above are not described in detail here.

[0042] In the above technical solution, the display window can be understood as a window used to display information to the user and receive user input.

[0043] In addition, the display device proposed in this application also has the following additional technical features.

[0044] In some technical schemes, optionally, the first display window among the M display windows corresponds to O display modules with touch functions, O is less than or equal to N, O is a positive integer greater than or equal to 1, and in the projection area of ​​the first display window in the circuit board, the O display modules with touch functions are arranged at the inner edge of the projection area.

[0045] In this technical solution, the arrangement of the display module with touch function corresponding to the first display window among the M display windows is defined, by arranging O display modules with touch function at the inner edge of the projection area.

[0046] In this technical solution, it can be ensured that the light emitted by the O display modules with touch functions can cover the first display window to the greatest extent, so as to ensure that the first display window can be clearly displayed to the user.

[0047] At the same time, the first display window can also detect the user's touch input, thereby realizing interaction, and combining with the first display window, the area capable of touch input is increased to the greatest extent.

[0048] In some technical solutions, optionally, O display modules with touch functions are arranged at intervals on the inner edge of the projection area.

[0049] In some technical solutions, optionally, O can be set according to the display brightness set by the rated setting of the first display window.

[0050] Specifically, when the rated display brightness is higher, the value of O is higher and the spacing is denser. Conversely, when the rated display brightness is lower, the value of O is lower and the spacing is looser.

[0051] In some technical solutions, optionally, the first display window is one display window among M display windows.

[0052] In some technical solutions, optionally, the display device further includes: Q light-emitting modules, located in the middle of the first display window; wherein Q is a positive integer greater than or equal to 1.

[0053] In this technical solution, a light emitting module is arranged in the middle of the first display window so as to utilize the light emitting module to improve the display brightness of the first display window. In this process, the value of Q can be selected according to actual use needs so as to obtain a number of light emitting modules that meets user needs.

[0054] In this technical solution, the light emitting module is used to improve the display brightness of the first display window, and at the same time, the manufacturing cost of the display device can be reduced.

[0055] In some technical solutions, optionally, the light emitting module is a light emitting diode.

[0056] In some technical schemes, optionally, the second display window among the M display windows corresponds to P display modules with touch functions, P is less than or equal to N, and P is a positive integer greater than or equal to 1; the second display window is in the projection area of ​​the circuit board, the first part of the P display modules with touch functions are arranged at the inner edge of the projection area, and the second part of the P display modules with touch functions are located in the middle of the second display window.

[0057] In this technical solution, the distribution of the display modules with touch functions corresponding to the second display window is defined, wherein the first part of the P display modules with touch functions corresponding to the second display window are arranged at the inner edge of the projection area, so that the light emitted by the display module can cover the second display window to the greatest extent, thereby ensuring that the second display window can be clearly displayed to the user.

[0058] At the same time, the second display window can also be made to detect the user's touch input, thereby realizing interaction, and combining with the second display window, the area capable of touch input can be increased to the greatest extent.

[0059] The second part of the P display modules with touch functions are arranged in the middle of the second display window, so as to use the P display modules with touch functions to realize the control of different display states of the second display window.

[0060] Specifically, for example, P is 5, the first part includes 4 display modules with touch function, and the second part includes 1 display module with touch function. Correspondingly, the 4 display modules with touch function are arranged at the inner edge of the projection area, and the 1 display module with touch function is located in the center of the projection area.

[0061] In some technical solutions, optionally, the controller is specifically used to: when the second display window receives user input, obtain a first sensing amount output by a first part of P display modules with touch functions and a second sensing amount output by a second part of P display modules with touch functions; and switch the display state of the second display window according to a comparison result of the first sensing amount, the second sensing amount and a preset threshold.

[0062] In this technical solution, a preset threshold can be set in advance so that the first sensing quantity output by the first part and the second sensing quantity output by the second part can be compared therewith, so as to control the first part and the second part to operate according to different parameters so as to realize the switching of the display state presented by the second display window. In this process, the display device can present multiple display states so as to present more information to the user.

[0063] In some technical solutions, optionally, the preset threshold includes a first threshold and a second threshold, and the controller is specifically used to: when the first sensing amount is greater than or equal to the first threshold, compare the second sensing amount with the second threshold; when the second sensing amount is greater than or equal to the second threshold, display the second display window in the first display state; when the second sensing amount is less than the second threshold, display the second display window in the second display state.

[0064] In this technical solution, there may be a size relationship between the first threshold and the second threshold, such as the first threshold is smaller than the second threshold. In this case, the above technical solution of the present application can realize the display of different display effects according to the distance between the touch and the second window.

[0065] In some technical solutions, optionally, the user interacts with the second display window through a finger. Specifically, when the user's finger approaches the second display window, since the first threshold is less than the second threshold, the display module with touch function arranged at the inner edge of the projection area first responds to the approach of the finger, such as controlling the display module with touch function of the first part to light up. At this time, since the second sensing amount does not reach the second threshold, the display module with touch function of the second part is not lit. At this time, the second display window is displayed in the second display state. As the finger approaches, the updated second sensing amount is greater than the second threshold. At this time, the display module with touch function of the second part is lit. At this time, the second display window is displayed in the first display state.

[0066] In some technical solutions, optionally, the user interacts with the second display window through a finger. Specifically, in the process of the user's finger approaching the second display window, since the first threshold is less than the second threshold, the display module with touch function arranged at the inner edge of the projection area first responds to the approach of the finger, such as controlling the display module with touch function of the first part to be displayed in the first color. At this time, since the second sensing amount does not reach the second threshold, the display module with touch function of the second part is displayed in the second color. At this time, the second display window is displayed in the second display state. As the finger approaches, the updated second sensing amount is greater than the second threshold. At this time, the display module with touch function of the second part is displayed in the first color. At this time, the second display window is displayed in the first display state.

[0067] In some technical solutions, optionally, the user interacts with the second display window through a finger. Specifically, when the user's finger approaches the second display window, since the first threshold is less than the second threshold, the display module with touch function arranged at the inner edge of the projection area first responds to the approach of the finger, such as controlling the display module with touch function of the first part to display at the first brightness. At this time, since the second sensing amount does not reach the second threshold, the display module with touch function of the second part is displayed at the second brightness. At this time, the second display window is displayed in the second display state. As the finger approaches, the updated second sensing amount is greater than the second threshold. At this time, the display module with touch function of the second part is displayed at the first brightness. At this time, the second display window is displayed in the first display state.

[0085] In this embodiment, a display module with a touch function is proposed, which can realize the touch input of the user while realizing the display of the pattern 106. In this process, since the light-emitting diode 108 with a touch function is used to realize the touch function, there is no need to stick an ITO touch film, so the problem that the display module is prone to failure due to the poor bending resistance of the ITO (ITO is an N-type oxide semiconductor-indium tin oxide) touch film in the related embodiments can be overcome.

[0086] In addition, since there is no need to stick an ITO touch film, the problem of poor contact caused by the plug-in end of the ITO touch film being easily affected by high temperature water vapor, vibration, etc. is avoided, thereby improving the reliability of the display module. At the same time, the display module with touch function proposed by the present invention can be applied to different working conditions.

[0136] Specifically, for example, P is 5, the first part includes 4 display modules with touch function, and the second part includes 1 display module with touch function.

At this time, since the second sensing amount does not reach the second threshold, the display module with touch function of the second part is displayed in the second color. At this time, the second display window is displayed in the second display state. As the finger approaches, the updated second sensing amount is greater than the second threshold. At this time, the display module with touch function of the second part is displayed in the first color. At this time, the second display window is displayed in the first display state.

[0144] In some embodiments, optionally, the user interacts with the second display window through a finger.
