Embodiments of the present application provide a display panel design method, a display panel design device, and an electronic device, which are described in detail below

As shown in fig. 1, a schematic diagram of an embodiment of a method for designing a display panel in an embodiment of the present application includes:

101. and acquiring product performance information of the display panel required by a user.

In this embodiment, when a designer (user) needs to design a product of a display panel, product performance information of the display panel to be designed may be configured in advance, where the product performance information of the display panel is configured product design performance information when the user designs the product, and the product performance information may include film material information of the display panel, actual measurement optical performance information (penetration rate, viewing angle, chromaticity, contrast, and the like) of the display panel, response time of the display panel, refresh frequency of the display panel, frame width of the display panel, and shape design type (plane or curved surface and the like) of the display panel. It should be understood that the above is only an example of the product performance information, and in practical applications, further product performance information may also be included, for example, product design size information, design resolution information, and the like, and the details are not limited herein.

103. And drawing a design drawing of the display panel based on the design parameters of the modules of the display panel.

Generally, the specification of the display panel is difficult to be completely defined, because the product is more subjective for the consumer, and the specifications of the display panel provided by different manufacturers are different, but for the designer, the requirements of the customer and the requirements of the manufacturers need to be converted into objective quantitative data as the design target, that is, the designable specification, that is, the design specification (professional specification). The design strategy information of the display panel can be preset in the embodiment of the application, that is, the design specification of the display panel or the design specification of the display panel can be preset, so that a designer can draw a pixel design drawing automatically according to the design strategy information of the display panel directly based on the design parameters of the display panel configured by a user during design.

Because the display panel technology is continuously improved and the design specifications of the display panel are continuously updated, the design strategies of the display panel can be synchronously updated if the design specifications of the display panel are updated due to the process refinement, the design optimization and the like in the following process.

Specifically, based on the design parameters of each module of the display panel, drawing the design drawing of the display panel may be: based on the design parameters of each module of the display panel, drawing a design drawing of the display panel in a preset drawing space, where the preset drawing space may be an initial design space of a design program or a design plug-in corresponding to the display panel design method, for example, a design space in Electronic Design Automation (EDA) for performing intelligent design of the display panel described in the subsequent embodiments.

It should be noted that, in the embodiment of the present application, because the processing is performed in the electronic device, each processing object exists in a form of data or information, for example, a display panel design policy, which is substantially display panel design policy information, it can be understood that line widths, sizes, numbers, positions, and the like mentioned in the following embodiments all exist in corresponding data, so that the electronic device performs processing, and details are not described herein.

In this embodiment of the present application, the execution flow of the display panel design method may be loaded in the display panel design program in the form of a plug-in, or may be a display panel intelligent design program independent of the display panel design program, as long as the display panel design parameters corresponding to the current design operation of the user can be collected in the display panel design program, and the specific details are not limited herein.

The display panel Design program may be an Electronic Design Automation (EDA) program designed by the existing display panel, such as protein, aluminum Designer, PSPICE, OrCAD, and the like.

Because all product performance information cannot be input sometimes during design of the display panel, on one hand, a designer can conveniently finish product design when inputting product performance parameters of types, and on the other hand, a design scene with less limitation is provided, therefore, in the embodiment of the application, a scheme for complete design according to partial product performance parameters of the display panel is provided, and at the moment, in some embodiments of the application, the product performance information comprises the product performance parameters of at least one display panel module; the number of the at least one display panel module may be less than the total number of all modules of the display panel.

It should be noted that the Display panel in the embodiment of the present application may be various types of Display panels, such as a Liquid Crystal Display (LCD) panel, an organic light-emitting diode (OLED) Display panel, and the like, and specifically, a Thin Film Transistor Liquid Crystal Display (TFT-LCD) panel, and the like.

The following description will be made of the design strategy information of the display panel, taking the TFT-LCD display panel as an example.

For the TFT-LCD display panel, many professional fields of knowledge are involved, and naturally many professional specifications are involved, which are not isolated from each other, and the design of the display panel is not simply a summation of all specifications, but rather, the design goal and positioning are determined in coordination with each other to ensure the final design success of the product.

For the TFT-LCD display panel, the design strategy information of the display panel includes TFT design strategy information, which is described below as an example.

The TFT design strategy information may include material and thickness strategy information, line width definition limitation strategy information, alignment error limitation strategy information, and TFT process parameter strategy information.

In a specific embodiment, the material and thickness strategy information may include material and thickness information of at least one of a gate electrode, a gate insulating layer, a semiconductor layer, a doped semiconductor layer, a source/drain metal, and a transparent electrode, and the material and thickness strategy information may specifically include the contents as in table 1 below. It is understood that the material and thickness strategy information in table 1 is only an example, and more or less material and thickness information may be included in practical applications, and is not limited herein.

TABLE 1

In a specific embodiment, the line width definition limitation policy information includes line width definition limitation information of at least one of a gate metal line, a semiconductor layer line, a source/drain metal line, a contact hole, and an ITO transparent electrode. Specifically, the line width definition limitation policy information may specifically include the contents as in table 2 below. It is understood that the line width definition limitation strategy information in table 2 is only an example, and more or less line width definition limitation information may be included in practical applications, and is not limited herein.

TABLE 2

In a specific embodiment, the alignment error limiting policy information includes alignment error limiting information of at least one of a semiconductor layer and a gate metal, a source drain metal and a semiconductor layer, a contact hole and a gate metal, a contact hole and a source drain metal, a transparent electrode and a gate metal, and a transparent electrode and a contact hole. Specifically, the alignment error limitation strategy information may specifically include the contents as in table 3 below. It is understood that the alignment error limitation strategy information in table 3 is only an example, and more or less alignment error limitation information may be included in practical applications, and is not limited herein.

TABLE 3

In a specific embodiment, the TFT process parameter policy information may include at least one of the process parameter information of electron mobility, the off-voltage, and the leakage current parasitic capacitance, and specifically, the TFT process parameter policy information may include the following contents in table 4, where it is understood that the TFT process parameter policy information in table 4 is merely an example, and more or less process parameter information of the TFT may be included in practical applications, and is not limited herein.

TABLE 4

In general, in order to design a display panel that can satisfy the requirements of the driving principle in all cases, the design concept of "worst case design" is adopted, i.e., the design is considered to be usable in the limit, and then there is no problem in other cases. For example, if the frame frequency of the picture is 60 to 75Hz, the charging time is considered as 75Hz, and the charge holding time is considered as 60Hz, so that if the charging time can be satisfied under two limit conditions, the charging time can be satisfied under other frequencies. Therefore, a similar principle is also adopted in the embodiments of the present application, and in the above table 1 to table 4, only a single numerical value is listed, which indicates that the value in the single numerical value is the worst design value, and the direction good with respect to the design value satisfies the design requirement, for example, the electron mobility of the TFT in table 4 is the worst design value, and generally, the higher the electron mobility of the TFT is, the higher the electron mobility is, the improvement of the display resolution can be indirectly facilitated, and therefore, the electron mobility is larger than the general value, that is, the design specification is satisfied.

It should be noted that, only a part of the TFT design policy information is illustrated in tables 1 to 4, and it is understood that, in addition to the TFT design policy information illustrated in the above examples, in the embodiment of the present application, any other more TFT design policy information, such as the number of terminals and the like, may be included according to actual needs.

In addition, in the practical application process, design strategy information of different display panels can be set for different display panels, and in order to achieve the optimization of a certain characteristic of the display panel, more design parameters can be set on the design strategy information of the related display panel, for example, in table 4, a general value in the electron mobility of the TFT is set to be a larger electron mobility value, so as to indirectly improve the resolution of the display and meet the design requirement of the display for higher resolution.

In the pixel design, two design values most closely related to all the design are the size of the storage capacitor and the channel width W of the TFT, respectively, and other designs are not unimportant and do not easily change, such as the channel length of the TFT, which is usually set at the minimum limit of the manufacturing capability to obtain the maximum off-current and the minimum gate load capacitance, such as the material and thickness of the gate insulating layer or the metal conductive layer.

At this time, as shown in fig. 2, the determining, in the preset display panel design parameter database, the design parameters of each module of the display panel that are matched with the product performance information may include:

201. searching design parameters of the display panel matched with the at least one display panel module in a preset display panel design parameter database according to the product performance information;

202. determining other display panel modules in the display panel except the at least one display panel module;

203. and searching the general design parameters preset by other display panel modules in a preset display panel design parameter database.

In this embodiment, for a display panel module with product performance information, the matched design parameters of the display panel are directly searched in the preset display panel design parameter database, and for a display panel module without product performance information, the general design parameters are directly searched in the preset display panel design parameter database, and all the required design parameters of the display panel are determined, so that the design, simulation and the like can be automatically completed in the subsequent process.

In addition, for the target type design parameters of the display panel module which cannot find the matched design parameters in the preset display panel design parameter database, the corresponding general target type design parameters can also be directly found, for example, if the design parameters 1 in the display panel module a cannot find the matched design parameters in the preset display panel design parameter database, the general design parameters 1 corresponding to the design parameters 1 in the display panel module a are directly found, all the required design parameters of the display panel are determined, so that the design, the simulation and the like can be automatically completed in the following process. After the subsequent automatic design, simulation and optimization are finished, and the design drawing information of the optimized display panel is obtained, the finally optimized target type design parameters of the display panel module which cannot find the matched design parameters before can be determined, and the finally optimized target type design parameters are updated to a preset display panel design parameter database, so that the display panel module can be conveniently used in the subsequent display panel design process.

Since the display panel parameters in the above embodiment are divided into two parts, the drawing the design drawing of the display panel based on the design parameters of each module of the display panel may include: drawing a design pattern of the at least one display panel module in the display panel based on the design parameters of the display panel matched with the at least one display panel module; and drawing the design patterns of the other display panel modules based on the preset general design parameters of the other display panel modules. Namely, the design patterns of the display panel modules are respectively drawn based on the design parameters of the different display panel modules.

In some embodiments of the present application, the display panel design parameter database stores display panel design parameters, such as pixel module design parameters (including pixel aperture ratio, pixel design architecture (4 partitions and 8 partitions)), gate driver design parameters (gate electrode driver design type (GOA/GOA COF), arrangement of GOA units, and the like), in a display panel module by display panel module, where the design parameters of each display panel module correspond to product performance information of the display panel.

In some embodiments of the present application, the at least one display panel module includes a pixel module and a gate driving module; the design parameters of the display panel matched with the at least one display panel module comprise pixel module design parameters and gate drive module design parameters; the drawing the design pattern of the at least one display panel module in the display panel based on the design parameters of the display panel matched with the at least one display panel module comprises: drawing a design pattern of a pixel module in the display panel based on the pixel module design parameter; and drawing a design pattern of the gate driving module in the display panel based on the design parameters of the gate driving module.

The method for drawing the design pattern of the pixel module in the display panel comprises the following steps (1) to (4) based on the pixel module design parameters, wherein the design size information of the display panel and the design resolution information of the display panel in the product performance information of the display panel required by a user comprise:

(1) and calculating the size of a single pixel of the display panel based on the design size information of the display panel and the design resolution information of the display panel.

For example, the design size 55' uhd (ultra high definition) of the display panel corresponding to the current pixel design, the diagonal length 138731.517152um of the effective display area, and the design resolution of the display panel is 2160 × 3840.

Since the design size of the display panel is generally the length of the diagonal of the display panel, in this case, the design size information of the display panel includes the diagonal length of the effective display area in the display panel, for example, the diagonal length 138731.517152um of the effective display area of 55' UHD.

The calculating the size of a single pixel of the display panel based on the design size of the display panel and the design resolution of the display panel may include: acquiring the length-width ratio of the display panel; according to the triangle pythagorean theorem, calculating the length and the width of an effective display area in the display panel according to the length-width ratio of the display panel and the diagonal length of the effective display area in the display panel; and respectively calculating the size of a single pixel in the display panel according to the length and the width of an effective display area in the display panel and the design resolution information of the display panel.

The aspect ratio (Style) of the display panel is generally fixed, such as 16: 9, there are also individual design variations, such as 21: 9, the aspect ratio of the display panel input by the user can be obtained.

How to calculate the size of a single pixel of the display panel based on the design size of the display panel and the design resolution information of the display panel is described below with reference to specific examples.

Design size of display panel: size (diagonal length in inches); aspect ratio of the display panel: a Style; design resolution of display panel: reso (resolution); single pixel size: pixel Length (A) and Pixel Width (B)

The Length (Length) and Width (Width) of the effective display area can be calculated by the following formulas:

Length2+Width2＝Size2

Length＝Width*Style

the size of a single pixel is obtained by dividing the Length (Length) and Width (Width) of the effective display area by the value of the resolution, respectively. For example: 55' UHD (diagonal 138731.517152um) aspect ratio 16: 9, calculating the length and width of the effective display area according to the triangle pythagorean theorem to be 1209600um and 680400um respectively, and designing the resolution to be 2160 × 3840, the calculation mode of the size of a single pixel can be as follows:

pixel length (A) 680400/2160-315 um

pixel width (B) ═ 1209600/3840/3(RGB) ═ 105um

(2) And drawing a pixel design drawing of the single pixel in the display panel based on the size of the single pixel in the display panel, the pixel module design parameter and the pixel design strategy information in the design strategy information of the display panel.

The pixel module design parameters may include design transmittance information of the display panel. Since the new product transmittance affects a plurality of factors, which are complex and specific, the designed transmittance may be predetermined by the user based on the same type of product, for example, the transmittance with the same display panel size may be used as the designed transmittance of the current display panel.

After determining the design transmittance of the display panel, the design aperture ratio of the current display panel pixel design may be determined, for example, the design transmittance is determined, a product B is used as an analogy, the material and the film layer are selected to be the same, and the a aperture ratio is calculated according to the a transmittance × B aperture ratio — a aperture ratio × B transmittance, where the product a is the current display panel. The design aperture ratio of the display panel pixel design determines the pixel layout that can subsequently be used to draw individual pixels in the display panel.

The pixel module design parameters in the embodiments of the present application include many kinds, which are not illustrated herein.

When the display panel is an LCD display panel, because the LCD display panel includes basic structures such as an array substrate, a liquid crystal cell, an upper polarizer, a color film substrate, and a lower polarizer, the pixel design strategy information may include first design strategy information of a pixel-related structure in the array substrate and second design strategy information of a pixel-related structure in the color film substrate, and at this time, the drawing of the pixel design drawing of a single pixel in the display panel based on the size of the single pixel in the display panel, the pixel module design parameters, and the pixel design strategy information in the design strategy information of the display panel may specifically include: drawing a reference pattern of a single pixel based on the size of the single pixel of the display panel; drawing an array substrate related structure pattern in a single pixel based on the first design strategy information; drawing a color film substrate-related structure pattern in an individual pixel based on the second design strategy information.
