Description

Display driving system, method and television

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 15, 2023, with application number 202311736286.5 and application name “A display drive system, method and television set”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of display drive technology, and in particular to a display drive system, method and television. Background Art

[0003] As higher resolutions and refresh rates have become the development trend of display screens, high-resolution and high-refresh displays place higher demands on data transmission speeds. Traditional display serial interfaces, such as Mini LVDS transmission technology, are unable to achieve high-speed data transmission. Therefore, the higher-speed P2P (Point to Point Interface) protocol has become the mainstream transmission technology for display screens.

[0004] Large-screen TVs are becoming increasingly popular, with even super-large sizes like 98-inch and 115-inch TVs appearing. The corresponding P2P transmission rates are as high as 3.5Gbps. The higher the signal frequency, the greater the attenuation through the signal and transmission lines. Technical issues

[0005] For large-size televisions, the P2P transmission line to the display screen is even longer and experiences greater attenuation. As shown in Figure 1, the TV comprises a Tconless motherboard 10 and a display screen 20. The display screen 20 comprises a display panel 21 and an X-circuit board (XPCB). The P2P signal must travel directly from the Tconless motherboard 10 to the source board (XPCB) at the display screen end, a distance exceeding one meter. Using a direct connection would fail the eye diagram signal test. Therefore, for large-size televisions, the Tconless motherboard 10 is not compatible with the display screen 20 due to the high P2P signal attenuation. Technical Solutions

[0053] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0054] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance or implicitly indicating the number of technical features indicated. The features specified as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0055] Referring to Figure 2 , this embodiment provides a display driver system connected to a display screen 300. The display driver system includes a main control module 100 and a re-driver module 200, with the main control module 100 connected to the re-driver module 200. In practical applications, the main control module 100 and the re-driver module 200 are each provided on two separate circuit boards. For example, the main control module 100 is directly provided on a mainboard, which is a Tconless mainboard, also known as a Tconless movement board; while the re-driver module 200 is independently provided on a re-driver circuit board.

[0056] During specific implementation, the main control module 100 is used to obtain the P2P signal to be transmitted and the target eye diagram template corresponding to the P2P signal to be transmitted, and output a gain control signal according to the P2P signal to be transmitted; the re-driving module 200 is used to adjust the gain of the P2P signal to be transmitted according to the gain control signal and then output it to the display screen 300, so that the eye diagram of the P2P signal received by the display screen 300 is adapted to the target eye diagram template, and the display screen 300 displays according to the received P2P signal.

[0057] The P2P signal in this embodiment refers to a driving signal in a P2P format, and the eye diagram is used to evaluate signal quality. When the P2P signal is transmitted to the display screen 300, a target eye diagram template will be generated when the P2P signal quality is optimal. Therefore, in this application, by pre-storing the target eye diagram template of the P2P signal in the main control module 100, after obtaining the P2P signal to be transmitted and the target eye diagram template of the P2P signal to be transmitted, the P2P signal to be transmitted is output to the re-driving module 200, and a gain control signal is output to the re-driving module 200 based on the P2P signal to be transmitted. The re-driving module 200 then adjusts the gain of the received P2P signal to be transmitted based on the gain control signal, thereby preventing excessive attenuation of the P2P signal received by the display screen 300 and ensuring that the eye diagram of the P2P signal received by the display screen 300 matches the target eye diagram template, thereby alleviating the problem of mismatch between the mainboard and the display screen 300 in large-size televisions due to attenuation during P2P transmission.

[0058] In some embodiments, the main control module 100 is specifically used to obtain the target transmission rate of the P2P signal to be transmitted and the target eye diagram template corresponding to the target transmission rate, and obtain the target adjustment parameter corresponding to the target transmission rate based on the mapping relationship between the preset transmission rate and the gain adjustment parameter, and output the gain control signal according to the target adjustment parameter.

[0059] There are different target eye diagram templates for P2P signals with different transmission rates, and the degree of attenuation of P2P signals with different transmission rates during transmission may also vary. Therefore, the gain that needs to be adjusted during transmission for P2P signals with different transmission rates may also be different. Therefore, the main control module 100 pre-stores a mapping relationship between transmission rate and gain adjustment parameters. In this embodiment, by obtaining the target eye diagram template of the P2P signal to be transmitted and determining the target transmission rate of the P2P signal to be transmitted, the target adjustment parameter of the target transmission rate is obtained based on the pre-stored mapping relationship between the target transmission rate and the gain adjustment parameter. Then, a corresponding gain control signal is output based on the target adjustment parameter to facilitate controlling the re-driving module 200 to perform gain adjustment on the P2P signal to be transmitted, thereby avoiding excessive attenuation of the P2P signal during transmission, which may cause quality problems in the P2P signal received by the display screen 300.

[0060] As an embodiment, there may be multiple gain adjustment parameters for each transmission rate mapping, and there may be multiple gain adjustment parameters for each transmission rate. The multiple gain adjustment parameters may have a step-by-step progressive relationship. Then, when performing gain adjustment, the P2P signal may be gain adjusted successively according to the multiple progressive gain adjustment parameters, thereby improving the accuracy of gain adjustment.

[0061] Referring to Figure 3, in some embodiments, the re-driving module 200 includes an input interface 210, a re-driving unit 220, and an output interface 230. The input interface 210 is connected to the main control module 100, the re-driving unit 220 is connected to the input interface 210, and the output interface 230 is connected to the re-driving unit. In specific implementations, the input interface 210 is used to receive the P2P signal to be transmitted and the gain control signal output by the main control module 100; the re-driving unit 220 is used to receive the P2P signal to be transmitted and the gain control signal, and to adjust the gain of the P2P signal to be transmitted based on the gain control signal; and the output interface 230 is used to output the P2P signal to be transmitted to the display screen 300. In this embodiment, a re-driving module 200 including an input interface 210, a re-driving unit 220, and an output interface 230 is provided to adjust the gain of the P2P signal to be transmitted according to the gain control signal output by the main control module 100. This can effectively prevent the P2P signal to be transmitted from being excessively attenuated during transmission to the display screen 300, resulting in poor quality of the P2P signal received by the display screen 300, thereby improving the compatibility between the mainboard and the display screen 300.

[0062] As an example, one input interface 210 is provided in this embodiment, specifically, input interface 210 is shown in FIG4 . Two output interfaces 230 are provided, one of which is connected to the connector on the left half of display screen 300, as shown in FIG5 ; the other of which is connected to the connector on the right half of display screen 300, as shown in FIG6 . One of output interfaces 230 outputs the drive signal required for the left half of display screen 300, while the other output interface 230 outputs the drive signal required for the right half of display screen 300, thereby achieving the driving display of display screen 300.

[0063] Continuing with FIG3 , in some embodiments, the re-driving module 200 further includes a reference voltage conversion unit 240 and an electrostatic protection unit 250. The reference voltage conversion unit 240 is connected to the input interface 210 and the output interface 230, respectively, and the electrostatic protection unit 250 is connected to the input interface 210. The reference voltage conversion unit 240 is used to convert the first voltage of the input interface 210 into a second voltage and then transmit it to the output interface 230; the electrostatic protection unit 250 is used to absorb the static electricity output by the input interface 210. In this embodiment, the reference voltage conversion unit 240 converts the first voltage of the input interface 210 into the second voltage to improve the driving capability of the current corresponding to the first voltage. The electrostatic protection unit 250 is used to absorb the static electricity output by the input interface 210 to effectively protect the re-driving module 200.

[0064] As an embodiment, the first voltage input to the reference voltage conversion unit 240 includes the CFVCM reference voltage and the DBSVCOM reference voltage, and the second voltages output after conversion are CFVCM1, CFVCM2, and DBSVCM respectively.

[0065] Referring to FIG. 7 , in some embodiments, the re-driving unit 220 includes a re-driving chip U1, which is connected to the input interface 210 and the output interface 230, respectively. The re-driving chip U1 is used to adjust the gain of the P2P signal to be transmitted output from the input interface 210 according to the gain control signal and then output it to the output interface 230. The model of the re-driving chip U1 in this embodiment can be TDP142. Of course, in other embodiments, a driving chip with the same function can also be selected, which is not limited in this application. In specific implementation, capacitors and resistors are also provided on the periphery of the re-driving chip U1 to ensure that the driving chip can work stably and effectively. The re-driving chip U1 in this embodiment performs gain adjustment on the input P2P signal to be transmitted, for example, amplifying the P2P signal before outputting it to the display screen 300 through the output interface 230, thereby avoiding excessive attenuation during the P2P signal transmission process, ensuring that the eye diagram of the P2P signal received by the display screen 300 is compatible with the target eye diagram template, and thereby alleviating the mismatch problem between the mainboard and the display screen 300 in large-size televisions due to attenuation during the P2P transmission process.

[0067] In this embodiment, both the first driver chip U2 and the second driver chip U3 are model G1582RD1U. Of course, other embodiments may also use driver chips with similar functionality, and this is not a limitation in this application. In this embodiment, the first driver chip U2 amplifies the input reference voltage CFVCM and outputs two reference voltages CFVCM1 and CFVCM2, thereby improving the current driving capability of the reference voltage CFVCM. Simultaneously, the second driver chip U3 amplifies the input reference voltage DBSVCOM and outputs the reference voltage DBSVCM, thereby improving the current driving capability of the reference voltage DBSVCOM.

[0072] Therefore, in the present application, the target eye diagram template of the P2P signal is pre-stored in the main control module. After obtaining the P2P signal to be transmitted and the target eye diagram template of the P2P signal to be transmitted, the P2P signal to be transmitted is output to the re-driving module, and a gain control signal is output to the re-driving module according to the P2P signal to be transmitted. The re-driving module adjusts the gain of the received P2P signal to be transmitted according to the gain control signal, thereby avoiding excessive attenuation of the P2P signal received by the display screen, ensuring that the eye diagram of the P2P signal received by the display screen is adapted to the target eye diagram template, thereby alleviating the problem of incompatibility between the main board and the display screen in large-size TVs due to attenuation during the P2P transmission process.

[0073] Referring to FIG. 12 , in some embodiments, step 101 includes:

[0074] 1011. Obtain a target transmission rate of a P2P signal to be transmitted and a target eye diagram template corresponding to the target transmission rate;

[0075] 1012. According to a preset mapping relationship between the transmission rate and the gain adjustment parameter, obtain a target adjustment parameter corresponding to the target transmission rate, and output a gain control signal according to the target adjustment parameter.

[0076] There are different target eye diagram templates for P2P signals with different transmission rates, and the attenuation degree of P2P signals with different transmission rates during the transmission process may also be different. Therefore, the gain that needs to be adjusted during the transmission process for P2P signals with different transmission rates may also be different. Therefore, the mapping relationship between the transmission rate and the gain adjustment parameter is pre-stored in the main control module. In this embodiment, the target eye diagram template of the P2P signal to be transmitted is obtained, and the target transmission rate of the P2P signal to be transmitted is determined. Then, the target adjustment parameter of the target transmission rate is obtained based on the pre-stored mapping relationship between the target transmission rate and the gain adjustment parameter. Then, the corresponding gain control signal is output based on the target adjustment parameter to facilitate the control of the re-driving module to perform gain adjustment on the P2P signal to be transmitted, thereby avoiding excessive attenuation of the P2P signal during the transmission process, which may cause quality problems of the P2P signal received by the display screen.
