[0025] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings. The described technical solutions are for illustrative purposes only and should not be construed as limiting the scope of protection of this application.
[0026] In the description of this application, it should be understood that the terms "first," "second," and similar words do not indicate any order, quantity, or importance, but are merely used to distinguish different technical features. The terms "multiple" and similar words mean two or more, unless otherwise expressly defined.
[0027] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.
[0028] The use of "applies to" or "configured to" in this application implies open and inclusive language, which does not exclude the applicability to or configuration to devices performing additional tasks or steps. Additionally, the use of "based on" implies openness and inclusivity, because processes, steps, calculations, or other actions "based on" one or more of the stated conditions or values may in practice be based on additional conditions or values beyond those stated.
[0029] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use this application.
[0030] The various embodiments of this application are similar, and features from different embodiments and / or different examples can be combined with each other.
[0031] In related technologies, such as Figure 1 As shown, the display device 100' includes a liquid crystal display panel 10', a backlight module, a display controller 20', and a circuit board 30'. The liquid crystal display panel 10' is located on the light-emitting side of the backlight module, and the backlight module is used to provide a light source for the liquid crystal display panel 10'.
[0032] The display controller 20' receives display data signals from the motherboard 200', processes them, and sends them to the liquid crystal display panel to control the rotation of liquid crystal molecules in the liquid crystal display panel, thereby controlling the display of images. The circuit board 30' is equipped with a power supply module 31' and a backlight driver module 32'. The power supply module 31' supplies power to the display controller 20' and the liquid crystal display panel. The backlight driver module 32' supplies power to the backlight module and also receives backlight data signals from the motherboard 200', processes them, and sends them to the backlight module to control the backlight brightness of the backlight module, thereby controlling the display brightness of the images.
[0033] However, since the power module 31' and the backlight driving module 32' are both mounted on the circuit board 30', the area of the circuit board 30' is relatively large, which is not conducive to the miniaturization of the display device 100'.
[0034] Based on this, some embodiments of this application provide a display device, such as... Figure 2 and Figure 3 As shown, the display device 100 includes a liquid crystal display panel 10, a backlight module, a display controller 20, a power supply module 31, a source driver 40, and a gate driver 50.
[0035] The backlight module provides a light source for the liquid crystal display panel 10, which is located on the light-emitting side of the backlight module. The liquid crystal display panel 10 includes multiple pixels, and by driving the activation of these multiple pixels, the display of an image on the liquid crystal display panel 10 can be achieved in cooperation with the backlight module.
[0036] Each pixel includes a pixel circuit, a pixel electrode connected to the pixel circuit, a common electrode, and liquid crystal molecules located between the pixel electrode and the common electrode. The liquid crystal molecules of multiple pixels together form a liquid crystal layer. After a pixel is activated, by applying a pixel voltage and a common voltage to the pixel electrode and the common electrode respectively, the rotation of the liquid crystal molecules in that pixel can be controlled, thereby controlling the light emission of that pixel. By applying voltages to the pixel electrodes and the common electrode of multiple pixels, the light emission of all pixels can be controlled, thereby enabling the display of an image on the liquid crystal display panel 10.
[0037] In some examples, multiple pixels may include multiple red subpixels, multiple green subpixels, and multiple blue subpixels, thus enabling the liquid crystal display panel 10 to display color images.
[0038] like Figure 2 and Figure 3As shown, the power module 31 is electrically connected to the display controller 20, the liquid crystal display panel 10, the backlight module, the source driver 40, and the gate driver 50. The power module 31 is configured to supply power to the display controller 20, the liquid crystal display panel 10, the backlight module, the source driver 40, and the gate driver 50. Thus, the power module 31 can simultaneously supply power to the display controller 20, the liquid crystal display panel 10, the backlight module, the source driver 40, and the gate driver 50, ensuring their normal operation. For example, the power module 31 can be mounted on a circuit board 30.
[0039] The display controller 20 is electrically connected to the backlight module, the source driver 40, and the gate driver 50. The display controller 20 is configured to: receive an image signal, process the image signal and generate a gate timing control signal, a source timing control signal and a backlight signal, send the gate timing control signal to the gate driver 50, send the source timing control signal to the source driver 40, and send the backlight signal to the backlight module.
[0040] The gate driver 50 is also electrically connected to the liquid crystal display panel 10. The gate driver 50 can be configured to receive gate timing control signals from the display controller 20 and output scan voltage signals to the pixels in the liquid crystal display panel 10 to drive all pixels to turn on line by line.
[0041] The source driver 40 is also electrically connected to the liquid crystal display panel 10. The source driver 40 can be configured to receive source timing control signals from the display controller 20 and output data voltage signals to the pixels in the liquid crystal display panel 10 to provide pixel voltages for all pixels. Furthermore, the power supply module 31 can output reference voltage signals to the pixels in the liquid crystal display panel 10 to provide a common voltage for all pixels. Thus, after each pixel is turned on, it can control the amount of light emitted by that pixel under the drive of the pixel voltage and the common voltage, thereby realizing the display of the image on the liquid crystal display panel 10.
[0042] In some examples, the backlight signal may include a PWM (Pulse Width Modulation) signal. By controlling the duty cycle of the PWM signal (i.e., the ratio of the high-level time to the entire cycle time), the backlight brightness can be controlled, thereby adjusting the brightness of the display screen of the liquid crystal display panel 10.
[0043] In the display device 100 provided in the above embodiments of this application, the power module 31 simultaneously supplies power to the display controller 20, the liquid crystal display panel 10, and the backlight module. After processing the image signal, the display controller 20 can simultaneously output gate timing control signals, source timing control signals, and backlight signals, thereby enabling the display of the image on the liquid crystal display panel 10. This eliminates the need for a backlight driver module, thus reducing the number of driver chips in the display device 100. This improves the simplification of the display device 100, facilitating its thinner and lighter design; it also eliminates the packaging and manufacturing costs of the driver chips corresponding to the backlight driver module, thereby reducing the manufacturing cost of the display device 100. Furthermore, since only the power module 31 is provided on the circuit board 30, the size of the circuit board 30 can be reduced, thus supporting applications of display devices with higher screen-to-body ratios.
[0044] For example, the display device described above can be a notebook computer or other display device used to implement display functions.
[0045] In some examples, there can be multiple source drivers 40, which can be distributed along the length of the liquid crystal display panel 10 to facilitate electrical connections between the source drivers 40 and all pixels. The multiple source drivers 40 can be mounted on a circuit board for support.
[0046] In some examples, there can be multiple gate drivers 50, which can be distributed along the width of the liquid crystal display panel 10 to facilitate electrical connections between the gate drivers 50 and all pixels. The multiple gate drivers 50 can be mounted on a circuit board for support.
[0047] It is worth noting that the electrical connection between C and D mentioned in this article can be a direct electrical connection between the two, or an indirect electrical connection formed through other components. The electrical connections of some components are not directly shown in the accompanying drawings; however, it can be understood that these components can be directly or indirectly connected.
[0048] In some embodiments, such as Figure 4As shown, the image signal includes a display data signal and a backlight data signal. The display controller 20 includes a timing control module 21 and a backlight data processing module 22. The timing control module 21 is electrically connected to the source driver 40 and the gate driver 50, and is configured to: receive the display data signal, process the display data signal and generate a gate timing control signal and a source timing control signal, send the gate timing control signal to the gate driver 50, and send the source timing control signal to the source driver 40. The backlight data processing module 22 is electrically connected to the backlight module, and is configured to: receive the backlight data signal, process the backlight data signal and generate a backlight signal.
[0049] This configuration, by splitting the display controller 20 into two modules to process and transmit display data signals and backlight data signals respectively, helps to improve the processing and transmission efficiency of display data signals and backlight data signals.
[0050] In some examples, both the timing control module 21 and the backlight data processing module 22 are electrically connected to the motherboard 300 to acquire display data signals and backlight data signals, respectively.
[0051] In some examples, the backlight data processing module 22 includes an LED constant current source circuit. For its specific circuit layout, you can refer to the specific structure of the existing LED constant current source circuit, which will not be described in detail here.
[0052] The timing control module 21 can also be configured with reference to the structure of existing timing controllers, and will not be described in detail here.
[0053] In some embodiments, such as Figure 3 and Figure 5 As shown, the gate driver 50 includes a GOA circuit 501, and the display controller 20 also includes a level conversion module 23. The timing control module 21 and the level conversion module 23 are electrically connected, and the GOA circuit 501 is electrically connected to the level conversion module 23 and the liquid crystal display panel 10.
[0054] The level conversion module 23 is configured to receive the gate timing control signal, perform level conversion on the gate timing control signal, and output a clock signal. The GOA circuit 501 is configured to receive the clock signal and generate a scan voltage signal based on the clock signal to drive all pixels in the liquid crystal display panel 10 to turn on line by line.
[0055] The GOA circuit 501 is a gate-driver-on-array (GOA) circuit, which is directly disposed on the liquid crystal display panel 10. On the one hand, it can reduce the area of the non-display area on the liquid crystal display panel 10 and increase the screen ratio of the liquid crystal display panel 10; on the other hand, it can avoid the bonding step of the source driver, thereby improving the assembly yield of the display device.
[0056] In addition, the level conversion module 23 can convert the received high-level gate timing control signal into a low-level signal, or convert the low-level gate timing control signal into a high-level signal, thereby ensuring that the GOA circuit 501 can work normally after receiving the gate timing control signal.
[0057] In some embodiments, such as Figure 6 As shown, the power module 31 includes a first sub-power module 311, a second sub-power module 312, a third sub-power module 313, a fourth sub-power module 314, and a fifth sub-power module 315. The first sub-power module 311 is electrically connected to the display controller 20 and configured to supply power to the display controller 20. The second sub-power module 312 is electrically connected to the liquid crystal display panel 10 and configured to supply power to the liquid crystal display panel 10. The third sub-power module 313 is electrically connected to the backlight module and configured to supply power to the backlight module. The fourth sub-power module 314 is electrically connected to the gate driver 50 and configured to supply power to the gate driver 50. The fifth sub-power module 315 is electrically connected to the source driver 40 and configured to supply power to the source driver 40.
[0058] This configuration, by dividing the power supply module 31 into five sub-power supply modules to supply power to the display controller 20, the liquid crystal display panel 10, the backlight module, the source driver 40, and the gate driver 50 respectively, helps to ensure the stability of the power supply to the display controller 20, the liquid crystal display panel 10, the backlight module, the source driver 40, and the gate driver 50.
[0059] Some embodiments of this application also provide a display terminal, such as... Figure 2 and Figure 3 As shown, the display terminal 400 includes a motherboard 300 and a display device 100 as described in any of the above embodiments. The motherboard 300 is electrically connected to the display controller 20 in the display device 100, thereby providing image signals to the display controller 20.
[0060] Since it includes a display device 100, the display terminal 400 has all the technical effects of the display device 100 described above, which will not be repeated here.
[0061] Some embodiments of this application also provide a display device, such as... Figure 7As shown, the display device 200 includes a liquid crystal display panel 10, a backlight module, a display controller 20, a power supply module 31, and a gate driver 50.
[0062] The power supply module 31 is electrically connected to the display controller 20, the liquid crystal display panel 10, the backlight module, and the gate driver 50. The power supply module 31 is configured to supply power to the display controller 20, the liquid crystal display panel 10, the backlight module, and the gate driver 50 simultaneously. Thus, the power supply module 31 can simultaneously supply power to the display controller 20, the liquid crystal display panel 10, the backlight module, and the gate driver 50, ensuring their normal operation. For example, the power supply module 31 can be mounted on a circuit board 30.
[0063] The display controller 20 is electrically connected to the backlight module and the gate driver 50, and the display controller 20 is configured to: receive image signals, process image signals and generate gate timing control signals and backlight signals, send the gate timing control signals to the gate driver 50, and send the backlight signals to the backlight module.
[0064] The gate driver 50 is also electrically connected to the liquid crystal display panel 10, and the gate driver 50 is configured to receive a gate timing control signal from the display controller 20 and output a scan voltage signal to the pixels in the liquid crystal display panel 10 to drive all pixels to turn on line by line.
[0065] In the display device 200 provided in the above embodiments of this application, the power module 31 simultaneously supplies power to the display controller 20, the liquid crystal display panel 10, and the backlight module. Furthermore, after processing the image signal, the display controller 20 can simultaneously output gate timing control signals and backlight signals, thereby enabling the display of the image on the liquid crystal display panel 10. This eliminates the need for a backlight driver module, thus reducing the number of driver chips in the display device 200. This improves the simplification of the display device 200, facilitating its thinner and lighter design; it also eliminates the packaging and manufacturing costs of the driver chips corresponding to the backlight driver module, thereby reducing the manufacturing cost of the display device 200. In addition, since only the power module 31 is provided on the circuit board 30, the size of the circuit board 30 can be reduced, thus supporting applications of display devices with higher screen-to-body ratios.
[0066] In some examples, the display controller 20 is configured to output data voltage signals to the pixels in the liquid crystal display panel 10. This provides pixel voltage to all pixels. In this case, the display controller 20 is a source driver (TCON embedded driver, TED) with an integrated timing controller, which eliminates the need for a separate source driver and improves the integration of the display controller 20. This, in turn, helps to simplify the display device 200 and increase assembly yield.
[0067] In some embodiments, such as Figure 8 As shown, the image signal includes a display data signal and a backlight data signal. The display controller 20 includes a timing control module 21, a backlight data processing module 22, and a source driver module 24. The timing control module 21 is electrically connected to the source driver module 24 and the gate driver 50, and is configured to: receive the display data signal, process the display data signal and generate a gate timing control signal and a source timing control signal, send the gate timing control signal to the gate driver 50, and send the source timing control signal to the source driver module 24. The backlight data processing module 22 is electrically connected to the backlight module, and is configured to: receive the backlight data signal, process the backlight data signal and generate a backlight signal.
[0068] This configuration, by dividing the display controller 20 into three modules to process the display data signal, source timing control signal, and backlight data signal respectively, helps to improve the processing efficiency of the display data signal and backlight data signal.
[0069] In some embodiments, such as Figure 7 and Figure 8 As shown, the gate driver 50 includes a GOA circuit 501, and the display controller 20 also includes a level conversion module 23. The timing control module 21 and the level conversion module 23 are electrically connected, and the GOA circuit 501 is electrically connected to the level conversion module 23 and the liquid crystal display panel 10.
[0070] The level conversion module 23 is configured to receive the gate timing control signal, perform level conversion on the gate timing control signal, and output a clock signal. The GOA circuit 501 is configured to receive the clock signal and generate a scan voltage signal based on the clock signal to drive all pixels in the liquid crystal display panel 10 to turn on line by line.
[0071] The GOA circuit 501 is a gate-driver-on-array (GOA) circuit, which is directly disposed on the liquid crystal display panel 10. On the one hand, it can reduce the area of the non-display area on the liquid crystal display panel 10 and increase the screen ratio of the liquid crystal display panel 10; on the other hand, it can avoid the bonding step of the source driver, thereby improving the assembly yield of the display device.
[0072] In addition, the level conversion module 23 can convert the received high-level gate timing control signal into a low-level signal, or convert the low-level gate timing control signal into a high-level signal, thereby ensuring that the GOA circuit 501 can work normally after receiving the gate timing control signal.
[0073] In some embodiments, such as Figure 9 As shown, the power module 31 includes a first sub-power module 311, a second sub-power module 312, a third sub-power module 313, and a fourth sub-power module 314. The first sub-power module 311 is electrically connected to the display controller 20 and configured to supply power to the display controller 20. The second sub-power module 312 is electrically connected to the liquid crystal display panel 10 and configured to supply power to the liquid crystal display panel 10. The third sub-power module 313 is electrically connected to the backlight module and configured to supply power to the backlight module. The fourth sub-power module 314 is electrically connected to the gate driver 50 and configured to supply power to the gate driver 50.
[0074] This configuration, by splitting the power module 31 into four sub-power modules to supply power to the display controller 20, the liquid crystal display panel 10, the backlight module, and the gate driver 50 respectively, helps to ensure the stability of the power supply to the display controller 20, the liquid crystal display panel 10, the backlight module, and the gate driver 50.
[0075] In some embodiments, the liquid crystal display panel 10 includes a display area and a non-display area located on at least one side of the display area, and a plurality of pixels of the liquid crystal display panel 10 are located in the display area; the display controller 20 is disposed in the non-display area and located at the center of one side of the display area.
[0076] This configuration places the display controller 20 in the middle of one side of the liquid crystal display panel 10, which facilitates the electrical connection between the display controller 20 and other related components, ensuring the stability and reliability of signal transmission.
[0077] Some embodiments of this application also provide a display terminal, such as... Figure 7 As shown, the display terminal 401 includes a motherboard 300 and a display device 200 as described in any of the above embodiments. The motherboard 300 is electrically connected to the display controller 20 in the display device 200, thereby providing display data signals and backlight data signals to the display controller 20.
[0078] Since it includes a display device 100, the display terminal 400 has all the technical effects of the display device 100 described above, which will not be repeated here.
[0079] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
