[0022] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present disclosure.

[0024] It should be noted that the terms "first," "second," and the like in the specification and claims of the present disclosure and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate for the embodiments of the present disclosure described herein. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or inherent to these processes, methods, products, or apparatus.

[0025] As introduced in the background technology, in the display device of the prior art, the display main board is electrically connected to the Tcon board, and electrically connected to the display panel through the Tcon board. This method requires connection to the source driver board of the panel through a connector, which not only increases the cost of the display architecture, but also makes the assembly process of the whole machine more complicated. It also occupies the already limited structural space, which is not conducive to the appearance structure design. The need to increase wires will also affect the signal delay and interference.

[0026] The traditional display architecture process is that the display motherboard outputs picture signals, such as low-voltage differential signaling (LVDS) and serial transmission protocol (V-BY-ONE). This protocol uses a pair of differential lines to transmit audio and video signals and can transmit video data of different resolutions and color depths. In addition, the various voltages provided by the power management module and the gamma correction voltage required by the control panel are sent to the source drive circuit and gate drive circuit of the control panel. The gate drive circuit is responsible for controlling the switching of each column of switching devices in the display panel. When the switching device is turned on, the source drive circuit can control the brightness, grayscale, etc. of each pixel, so that the picture can be displayed normally on the display panel.

[0027] To address the complex assembly process of display architectures, as well as the issues of extended signal transmission and strong interference, the present disclosure provides an integrated circuit board, as shown in FIG1 , electrically connected to a display panel 200 . The integrated circuit board includes a main control module 10 , a power management module 20 , and a level conversion module 30 , wherein:

[0028] The main control module 10 is configured to receive picture information, generate a picture data signal according to the picture information, output the picture data signal to the display panel 200, and output a switching clock signal to the level conversion module 30;

[0029] The power management module 20 is connected to the main control module 10 and is configured to output a source drive voltage to the display panel 200 and output a gate drive voltage to the level conversion module 30;

[0030] The level conversion module 30 is connected to the main control module 10 and the power management module 20 respectively, and is configured to output a switching level signal to the display panel 200 according to the switching clock signal and the gate driving voltage.

[0031] Through the embodiment of the present disclosure, the above-mentioned main control module, power management module and level conversion module are integrated into the same circuit board in an integrated design. Compared with the display architecture with a timing control board and a display main board in the prior art, various picture signals, voltages and control signals required by the display panel can be directly sent to the display panel through an integrated circuit board to achieve normal display of the display panel, thereby not only reducing the cost of the display architecture, but also simplifying the TV assembly process, while being beneficial to the appearance structure design, making the display device lighter and simpler. In addition, the transmission signal delay and interference caused by long signal lines are also reduced.

[0032] In addition, the embodiment of the present disclosure can also integrate the functions of the source driver board into the integrated circuit board, so that there is no need to use a source driver board in the TV separately, reducing various costs such as wires, source driver boards, and source driver board brackets, and further simplifying the TV assembly process.

[0033] Specifically, as shown in Figure 1, the integrated circuit board in the embodiment of the present disclosure includes the above-mentioned main control module 10, power management module 20 and level conversion module 30. The main control module 10, power management module 20 and level conversion module 30 are all electrically connected to the display panel 200, wherein the power management module 20 is responsible for providing the various voltages required by the level conversion module 30 and the display panel 200. The main control module 10 forwards the picture information required by the display panel 200 to the display panel 200, and simultaneously sends a switching clock signal to the level conversion module 30, so that the level conversion module 30 outputs a switching level signal to the display panel 200 according to the switching clock signal and the gate drive voltage provided by the power management module 20. The display panel 200 switches the picture information in a timely manner according to the switching level signal and the picture data signal.

[0034] In some optional embodiments, as shown in Figure 1, the integrated circuit board in the embodiment of the present disclosure also includes an interface module 60, which includes multiple input ports and multiple output ports corresponding to the input ports one by one. The picture data signal, source drive voltage and switch level signal output by the main control module 10 are transmitted to the display panel 200 through different input ports and corresponding output ports.

[0035] In the above optional embodiment, as shown in FIG2 , the switching level signal output by the level conversion module to the display panel may include a clock input signal (CLK1_L, CLK2_L, ... CLKN_L) and a pull-down circuit control signal (LC1_L, ... LCn_L), so that the display panel controls each row or column of pixels in the pixel array of the display panel to be turned on or off according to the gate drive voltage, the clock input signal (CLK1_L, CLK2_L, ... CLKN_L) and the pull-down circuit control signal (LC1_L, ... LCn_L); the multiple input ports include a first input port (IN1_1, IN2_1, ... INN_1) and a second input port (IN1_2, ... INn_2), and the multiple output ports include a first output port (OUT 1_1, OUT2_1, ... OUTN_1) and a second output port (OUT1_2, ... OUTn_2), a clock input signal (CLK1_L, CLK2_L, ... CLKN_L) is transmitted to the display panel through the first input port (IN1_1, IN2_1, ... INN_1) and the first output port (OUT1_1, OUT2_1, ... OUTN_1), and a pull-down circuit control signal (LC1_L, ... LCn_L) is transmitted to the display panel through the second input port (IN1_2, ... INn_2) and the second output port (OUT1_2, ... OUTn_2), the number of the first input port and the first output port is the same as the number of rows of pixels in the pixel array, wherein N is a natural number greater than 2, and n is a natural number greater than 1.

[0036] In some optional embodiments, as shown in Figure 3, the main control module is electrically connected to the source driver circuit 50, and is configured to output a picture data signal and a switching clock signal, so that the source driver circuit 50 controls the switch module (not shown in the figure) in the display panel to charge and discharge the pixels in the pixel array according to the picture data signal and the switching clock signal; the level conversion module is electrically connected to the gate driver circuit 40, and is configured to output a switching level signal, so that the gate driver circuit controls the above-mentioned switch module to switch each row of pixels in the pixel array according to the switching level signal; the above-mentioned gate driver circuit 40 and the above-mentioned source driver circuit 50 are electrically connected to the above-mentioned switch module respectively.

[0037] It should be noted that the above-mentioned gate driving circuit 40 and the above-mentioned source driving circuit 50 can be integrated in the display panel 200, and the display panel 200 is electrically connected to the integrated circuit board 100 through the above-mentioned gate driving circuit 40 and the above-mentioned source driving circuit 50, as shown in Figure 3. The above-mentioned gate driving circuit 40 and the above-mentioned source driving circuit 50 are also externally placed on the integrated circuit board 100 and the display panel 200, as shown in Figure 4. The embodiments of the present disclosure are not specifically limited.

[0038] Specifically, the display panel 200 includes a pixel array and a switch module electrically connected to each pixel in the pixel array. The switch module is configured to control whether the pixel is lit. The switch module may include a thin film transistor. After receiving the gate drive voltage output by the level conversion module 30, the gate drive circuit 40 outputs a switching clock signal to a plurality of scan lines. The scan lines are connected to the gate terminals of each thin film transistor (TFT), thereby controlling the switching of each row or column of thin film transistors in the display panel. After receiving the source drive voltage, the source drive circuit 50 outputs a picture data signal to a plurality of data lines. The data lines are connected to the source terminals of each thin film transistor. When the thin film transistor is turned on, the source drive circuit 50 can control the brightness, grayscale, etc. of the pixel electrically connected to the turned-on thin film transistor, so that the pixel displays the image corresponding to the picture data signal.

[0039] In the above optional embodiment, the voltage provided by the power management module 20 to the display panel 200 includes a source drive voltage, which may include a main voltage and a common voltage. The voltage provided by the power management module 20 to the level conversion module 30 includes a gate drive voltage, which may include a turn-on voltage for the switch module and a turn-off voltage for the switch module. It should be noted that the various voltages provided to the display panel are not limited to the above types and are not specifically limited in this disclosure.

[0040] Exemplarily, the above-mentioned switching device can be a thin film transistor. In addition to the pixel array and the switching module electrically connected to each pixel in the pixel array, the display panel 200 also has a liquid crystal capacitor, one end of the liquid crystal capacitor is electrically connected to the drain of the thin film transistor, and the other end of the liquid crystal capacitor is connected to the common end. The power management module 20 is respectively connected to the source driver circuit 50 and the common end of the thin film transistor, and is configured to output the main voltage AVDD to the source driver circuit 50, and output the common end voltage VCOM to the common end COM; the source driver circuit 50 is also connected to the source of the thin film transistor, and is configured to output the picture data signal Data to the thin film transistor; the level conversion module 30 is connected to the thin film transistor, and is configured to output the switching clock signal CK to the thin film transistor according to the turn-on voltage VGH to turn on the thin film transistor, and output the switching clock signal CK to the thin film transistor according to the turn-off voltage VGL to turn off the thin film transistor.

[0041] For example, the power management module 20 is part of the timing control (Tcon) board in the traditional display architecture. The turn-on voltage (VGH) of the thin film transistor in the display panel 200 needs to be above 20V, and the turn-off voltage (VGL) of the thin film transistor needs to be below -5V. The high level of the switching clock signal output by the main control module 10 is generally 3.3V, so the power management module 20 needs to convert the switching clock signal output by the main control module 10 into the level required by the display panel 200. Therefore, the power management module 20 can also convert the switching clock signal sent by the main control module 10 into the panel switching signal required by the display panel 200, and send the panel switching signal to the display panel 200.

[0042] Exemplarily, the power management module 20 includes: a DC / DC switching power supply, an LDO differential linear regulated power supply, and resistors and capacitors of the control part. The DC / DC switching power supply can realize the conversion of different DC power supply values, converting DC power of a certain voltage level into DC power of other voltage levels. The DC / DC switching power supply can be divided into a boost power supply and a buck power supply according to the voltage level conversion relationship, and can be divided into an isolated power supply and a non-isolated power supply according to the input-output relationship. The LDO differential linear regulated power supply is a linear regulator that can still maintain a stable output voltage when the input voltage or load current changes. It uses transistors or field-effect transistors operating in its saturation region. The adjustment tube in the LDO differential linear regulated power supply is a P-type channel MOSFET. The P-type channel MOSFET is voltage-driven and does not require current, which greatly reduces the current consumption of the device itself. The voltage drop on the P-type channel MOSFET is approximately equal to the product of the output current and the on-resistance. Since the on-resistance of the MOSFET is very small, the voltage drop of the LDO differential linear regulated power supply is very low.

[0043] In some optional embodiments, the integrated circuit board in the embodiment of the present disclosure further includes a gamma module (not shown in the figure), which is communicatively connected to the main control module 10 and configured to output a gamma correction voltage to the display panel 200 under the drive of the main control module 10.

At the same time, the gate drive circuit 40 and the source drive circuit 50 can also control the display of the second display area through the picture data signal, source drive voltage and switching level signal transmitted by the second interface sub-module 602.
