Description

Technical Field

[0001] This invention relates to the field of liquid crystal display technology, and in particular to a method, display device, and electronic device for determining eye diagram levels. Background Technology

[0002] An eye diagram is a graphical representation of a series of digital signals accumulated on an oscilloscope. It allows observation of intersymbol interference (ISI) and noise, thus providing an estimate of the system's performance. Due to the superposition of multiple signals, the signal lines in the eye diagram thicken, resulting in a blurring effect. Therefore, the eye diagram also reflects signal noise and jitter.

[0003] Currently, with the continuous increase in display panel size and refresh rate, eye diagram problems caused by signal attenuation in display panels are gradually increasing. Research has found that in large-size, high-refresh-rate display panels, due to process deviations between different raw material manufacturers, the optimal eye diagram level will be different for different PCB (Printed Circuit Board), FPC (Flexible Printed Circuit), and COF (Chip On Flex) configurations. The same eye diagram level cannot be applied to all configurations.

[0004] If the eye diagram level is not set optimally, the image signal cannot be optimally compensated, which may result in noise during image display, failing to meet shipping requirements and causing yield loss. Summary of the Invention

[0081] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0082] In this embodiment of the invention, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0083] The application scenarios described in the embodiments of this invention are for the purpose of more clearly illustrating the technical solutions of the embodiments of this invention, and do not constitute a limitation on the technical solutions provided by the embodiments of this invention. Those skilled in the art will understand that with the emergence of new application scenarios, the technical solutions provided by the embodiments of this invention are also applicable to similar technical problems. In the description of this invention, unless otherwise stated, "multiple" means two or more.

[0084] Before introducing the method for determining eye diagram level provided in the embodiments of this application, the technical background of the embodiments of this application will be described in detail below for ease of understanding.

[0085] To evaluate the performance of a baseband transmission system, an oscilloscope is typically used in the laboratory to observe the received signal waveform and analyze the impact of intersymbol interference (ISI) and noise on system performance. This is known as eye diagram analysis. An eye diagram is a graphical representation of a series of digital signals accumulated on an oscilloscope. It contains a wealth of information, allowing observation of the effects of ISI and noise, reflecting the overall characteristics of the digital signal, and thus estimating the system's performance. Therefore, eye diagram analysis is central to signal integrity analysis in high-speed interconnect systems. Furthermore, this graph can be used to adjust the characteristics of the receiving filter to reduce ISI and improve system transmission performance. Figure 1A-1B As shown in the figure, this embodiment provides an eye diagram with different signal qualities, wherein... Figure 1A In an ideal scenario, with no signal distortion, the waveforms will overlap, resulting in a fine and clear "eye" on the oscilloscope, with the "eye" fully open. Figure 1B In the process, when there is interference, the signal is distorted, the waveforms do not completely overlap, the lines of the eye diagram become blurred, and the "eye" opens to a smaller extent.

[0086] Currently, with the continuous increase in display panel size and refresh rate, eye diagram problems caused by signal attenuation in display panels are gradually increasing. Research has found that in large-size, high-refresh-rate display panels, due to process variations among different material manufacturers, the optimal eye diagram level varies depending on the PCB (Printed Circuit Board), FPC (Flexible Printed Circuit), and COF (Chip On Flex) configurations. Therefore, the same eye diagram level cannot be applied to all configurations. Different configurations refer to modules provided by different suppliers / manufacturers, such as PCBs, FPCs, and COFs from different manufacturers. High-speed signals are significantly affected by the transmission medium. Currently, TV panels using XPCB, COF, and FPC commonly employ multi-supplier assembly. Due to differences in manufacturing processes, different manufacturers may exhibit some deviations even when achieving the same target values. Although all meet SPEC (Standard Performance Evaluation Corporation) requirements, the increasing refresh rates mean that even small differences in transmission lines can lead to differences in the final signal's eye diagram. If the eye diagram settings are not optimal, optimal signal compensation for the image signal cannot be achieved, potentially resulting in noise during image display, failing to meet shipment requirements, and causing yield losses. Figure 2As shown in the figure, this embodiment provides a difference diagram of signal eye diagram testing under the same EQ (eye diagram equalization) setting for different configurations. The eye diagram corresponding to XPCB, COF, and FPC being configuration 1 is different from the eye diagram corresponding to XPCB and COF being configuration 1 and FPC being configuration 2. That is, when different modules have different configuration information (such as manufacturer information), there are differences in the corresponding eye diagrams under the same EQ setting.

[0087] Based on this, this application provides a method for determining the eye diagram level, which can determine the eye diagram level matching the combination information from the mapping relationship by reading the combination information of different modules, thereby determining the optimal compensation value of the image signal, which can solve the problem of signal quality performance deviation caused by different combination information and effectively reduce yield loss.

[0088] like Figure 3 As shown in the figure, this embodiment provides a method for determining the eye diagram level. The specific implementation process of this method is as follows:

[0089] Step 300: Read the assembly information of different modules contained in the display device, wherein the assembly information includes manufacturer information;

[0090] In some embodiments, the different modules include a printed circuit board (PCB) and a timing controller (TCON) board. Optionally, assembly information is stored in the PCB, and the assembly information of the different modules stored in the PCB is read by the TCON board. Optionally, the PCB in this embodiment includes an XPCB (horizontal PCB).

[0091] In practice, the assembly information can be stored in the XPCB's memory (Flash).

[0092] Optionally, the assembly information in this embodiment includes information such as the manufacturer (supplier) information of different modules, for example, the serial code information corresponding to the manufacturer.

[0093] Step 301: Determine the mapping relationship between different combination information and eye diagram level, wherein the mapping relationship is obtained by adjusting the eye diagram level corresponding to different combination information based on the image signal quality of the eye diagram;

[0094] In implementation, different eye diagram levels are used for signal compensation of image signals of varying quality. During development, the optimal eye diagram level can be determined based on different XPCB, FPC, and COF configurations. An example of the mapping relationship is shown in the table below:

[0095] Table 1. Mapping relationship between different combination information and eye diagram levels

[0096]

[0097] In Table 1, the eye diagram settings include pre-emphasis settings and equalization settings. The pre-emphasis settings include Pre and Swing, and the equalization settings include EQ (eye diagram equalization). H or L under EQ indicates different settings. A total of 8 settings can be set: HHH, HHL, HLH, HLL, LHH, LHL, LLH, and LLL. Different settings correspond to different signal compensation values.

[0098] In some embodiments, the mapping relationship is determined by one or more of the following methods:

[0099] Method 1) The mapping relationship stored in the PCB read by the TCON board is determined as the mapping relationship between different assembly information and eye diagram levels;

[0100] In practice, the mapping relationship can be stored in the XPCB's memory (Flash). The TCON (Logic Board) reads the mapping relationship from the XPCB's Flash to determine the eye diagram position that matches the assembly information.

[0101] Method 2) The mapping relationship read by the TCON board from its own storage is determined as the mapping relationship between different combination information and eye diagram positions.

[0102] Step 302: Based on the mapping relationship between different combination information and eye diagram levels, determine the eye diagram level that matches the read combination information, wherein the eye diagram level that matches the combination information is used to determine the optimal compensation value of the image signal, and the optimal compensation value is used to perform signal compensation on the image signal.

[0103] In some embodiments, signal compensation can also be performed through the following steps:

[0104] 1a) Determine the optimal compensation value for the image signal based on the eye diagram level matched by the read combination information;

[0105] In some embodiments, the optimal compensation value for the image signal is determined based on the eye diagram level matched by the read combination information through the following steps:

[0106] Based on the eye diagram level matched by the read assembly information, determine the optimal compensation value for the image signal of the TCON board and the optimal compensation value for the image signal of the COF.

[0107] 1b) Compensate the image signal according to the optimal compensation value.

[0108] In practice, signal compensation is performed on the image signals of the TCON board and the COF flip-chip film according to the optimal compensation value.

[0109] In practice, the mapping relationship can be stored in the TCON's memory. The TCON reads the mapping relationship from its own memory to determine the eye diagram position that matches the matching information.

[0110] Optionally, the eye diagram settings in this embodiment include a pre-emphasis setting and an equalization setting. The pre-emphasis setting is used to determine the optimal compensation value corresponding to the image signal of the TCON board, and the equalization setting is used to determine the optimal compensation value corresponding to the image signal of the COF. The pre-emphasis setting includes a Pre setting and a Swing setting; the equalization setting includes an EQ setting. By adjusting different eye diagram settings, the quality of the eye diagram image signal is optimized.

[0111] In some embodiments, the image signal is compensated based on the optimal compensation value in the following manner:

[0112] Based on the pre-emphasis level in the matched eye diagram, determine the optimal compensation value corresponding to the image signal of the TCON board, and perform signal compensation on the image signal of the TCON board based on the optimal compensation value;

[0113] Based on the equalization setting in the matched eye diagram settings, the optimal compensation value corresponding to the image signal of the flip-chip COF is determined, and the image signal of the COF is compensated according to the optimal compensation value.

[0114] In practice, pre-emphasis processing is applied to the image signal on the TCON board; the pre-emphasis level corresponds to the transmitting end (TCON board). Upon power-on, the TCON board reads the pre-emphasis level and performs signal compensation. Equalization processing is applied to the COF (Chip-on-Flush Object), and the equalization level corresponds to the receiving end (COF). Upon power-on, the TCON board reads the corresponding equalization level and applies it to the COF image signal via IIC communication, thereby compensating for the attenuated image signal.

[0115] like Figure 4A As shown in the diagram, this embodiment provides a schematic diagram of an image signal from a TCON board. In the diagram, VOD represents a programmable differential output voltage, and VODDE represents a stable differential output voltage. The TCON board acts as the transmitter of the image signal. The image signal can be compensated through pre-emphasis processing. Upon power-on, the TCON board reads the pre-emphasis level from the eye diagram and then compensates the image signal of the TCON board according to the optimal compensation value corresponding to the pre-emphasis level.

[0116] like Figure 4BAs shown in the figure, this embodiment provides a schematic diagram of an image signal from a COF (Chip-on-Flight) converter. In the figure, EQR represents an eye diagram equalizer, and BR represents the pole frequency. The COF acts as the receiver of the image signal. The image signal can be compensated through equalization processing. Upon power-on, the TCON board reads the equalization level from the eye diagram and transmits it to the COF. Based on the optimal compensation value corresponding to the equalization level, the image signal from the COF is compensated.

[0117] In implementation, the mapping relationship can be encoded and stored. For example, this embodiment provides an encoding example where the combination information is encoded using 2 bits and the eye diagram position is encoded using 4 bits. The combination information uses a total of 3 × 2 = 6 bits for encoding, and the eye diagram position uses a total of 3 × 4 = 12 bits for encoding, for a total of 18 bits of binary encoding. A specific example is shown below:

[0118] FPC: Assembly 1→01;

[0119] XPCB: Assembly 1→01;

[0120] COF: Combination 2→10;

[0121] Pre: 4→0100;

[0122] Swing: 14 → 1110;

[0123] EQ: HHL→0110;

[0124] Therefore, the binary code corresponding to the mapping relationship between the combination information and the eye diagram position can be represented as: 010110010011100110, where the first 6 bits represent the combination information and the last 12 bits represent the eye diagram position matched by the combination information.

[0125] This embodiment provides an automatic eye diagram matching scheme for multiple assembly signals of XPCB, FPC, and COF. By adding the function of recognizing the assembly information of XPCB, FPC, and COF during the assembly process of each module of the display device, the assembly information is stored in XPCB Flash. When the TCON is turned on, the assembly information is read and matched to obtain the optimal eye diagram position.

[0126] During implementation, the assembly information (encoded values) of XPCB, FPC, and COF are identified during the module production process. The assembly information of the display panel is stored in the Panel XPCB Flash. The table below shows an example of the assembly information of 8 panels.

[0127] Table 2 Example of Assembly Information

[0128]

[0129]

[0130] The code encoding specifications for the panel assembly information are the same as the encoding specifications for the first 6 digits of the TCON Setting Code assembly information.

[0131] like Figure 5 As shown, this embodiment provides an XPCB Flash storage table, where area A is used to store the mapping relationship between different assembly information and eye diagram levels, and area C is used to store the assembly information of different modules. The mapping relationship in area A and the assembly information in area B can both be represented using encoding. Area B is used to store other encoded information. After mass production, the use of this scheme can be confirmed by reading the encoded information in the XPCB Flash.

[0132] In this embodiment, multiple configuration information is stored in the XPCB board. When the TCON is turned on, it reads the configuration information and matches the optimal eye diagram setting. For example... Figure 5 As shown in the figure, this embodiment provides an implementation flow for a method to determine the optimal eye diagram level, as detailed below:

[0133] Step 500: Based on the image signal quality of the eye diagram, adjust the eye diagram level corresponding to different combination information to determine the mapping relationship between different combination information and eye diagram level;

[0134] Step 501: Store the mapping relationship in the XPCB Flash or TCON board memory, and store the assembly information of different modules in the XPCB Flash.

[0135] Step 502: The TCON board reads the assembly information of different modules in the XPCB Flash;

[0136] Step 503: The TCON board searches for the eye diagram position that matches the grouping information in the mapping relationship;

[0137] Step 504: The TCON board uses the pre-emphasis setting in the eye diagram to determine the optimal compensation value corresponding to the image signal of the TCON board, and performs signal compensation on the image signal of the TCON board according to the optimal compensation value;

[0138] Step 505: The TCON board uses the equalization setting in the eye diagram to determine the optimal compensation value corresponding to the COF image signal, and performs signal compensation on the COF image signal according to the optimal compensation value.

[0139] like Figures 6A-6BAs shown in the diagram, this embodiment also provides a partial structural schematic of a display device, including a TCON board, an XPCB, a COF, and an FPC. The FPC represents the data transmission path, and the COF, FPC, and XPCB collectively influence the selection of the pre-emphasis level and the equalization level. The configuration information of different modules is stored in the XPCB Flash. After power-on, the TCON board reads the configuration information from the XPCB Flash, determines the eye diagram level matching the configuration information by searching the mapping relationship between different configuration information and eye diagram levels, and then determines the optimal compensation value corresponding to the image signal of the TCON board based on the pre-emphasis level in the eye diagram level, performing signal compensation on the image signal of the TCON board. Similarly, it determines the optimal compensation value corresponding to the image signal of the COF based on the equalization level in the eye diagram level, performing signal compensation on the image signal of the COF.

[0140] Based on the same inventive concept, this embodiment of the invention also provides a display device.
