Description

Technical Field

[0001] This application belongs to the field of display device manufacturing technology, specifically relating to a multi-temperature electronic paper driving waveform (WF) adjustment method and system. Background Technology

[0002] Electronic paper is a display screen made using electrophoretic display technology. It achieves the effect of displaying images by driving the electronic paper particles through the continuous application of an electric field with a driving waveform to each pixel by a driving IC chip.

[0003] In the existing technology, two-color electronic paper encapsulates black and white charged particles in the same capsule structure, while three-color electronic paper encapsulates three charged particles of different colors, such as black, white and red or black, white and yellow, in the same microcup structure. The movement of black, white and red particles with different charges is controlled by an external electric field to display black, white and red colors or black, white and yellow display effects.

[0004] The production process of three-color electronic paper modules has high requirements, and it is difficult to control the consistency within a small deviation range. At high temperatures, due to the increased activity of some particles and the increased uncertainty of particle movement or shaking, some batches of black, white and red electronic paper modules are prone to blurry fonts at 40°C.

[0005] Optical testing of electronic paper must comply with standards such as IEC 62679-3-1 and requires the use of non-contact specialized equipment. The following are the mainstream tool classifications and typical equipment: I. Basic Optical Performance Testing Equipment: Spectrophotometer / Whiteness Meter, Function: Measures parameters such as reflectance (blue light whiteness R457), fluorescence whitening, chromaticity (L×a×b× value), and opacity. Multi-angle Gloss Meter, Application: Analyzes the optical properties of electronic paper surfaces (such as specular reflection and diffuse reflection distribution).

[0006] II. Surface Uniformity and Defect Detection Equipment: Optical Imaging Analysis System: Function: High-resolution scanning of electronic paper surfaces to detect and display mura and uniformity issues. Equipment Examples: Opti / TOPO Paper Surface Uniformity Testing System: Equipped with a 12-bit grayscale camera and dual LED light sources, supporting analysis of areas from 6.5×6.5mm to 30×30mm. Online AOI Optical Inspection Instrument: Employs vector imaging technology to identify 0201-sized component-level defects (accuracy ±0.02°), suitable for electronic paper delamination / bubbling detection. Laser Confocal Microscope: Application: Microstructure observation (e.g., microcapsule distribution uniformity).

[0007] III. Dynamic Performance and Reliability Testing Equipment: Display Screen Analyzer, Function: Quantifies dynamic parameters such as refresh rate, ghosting, and response time. Equipment Example: Konica Minolta CA-410 Display Screen Analyzer. Environmental Simulation Equipment: Equipment Examples: ESPEC PL-3KPH Climate Chamber: Performs IEC 60068-2-78 constant humidity and heat test. Xenon ArcCi4000 Weathering Chamber: Simulates ultraviolet aging environment.

[0008] IV. Specialized Readability Testing Equipment: Test Items: Brightness / Contrast: Measured under standard ambient light (500±50 lux). Image Residual Detection: Analyzes residual images through grayscale switching response. Resolution Test: Evaluates the display clarity of small text / graphics.

[0009] In electronic paper technology, WF is short for "Waveform," referring to the voltage-time sequence that controls the display effect of electronic paper. It is a core component of electronic paper displays, achieving image refresh and color changes by adjusting the electric field to drive the movement of charged particles within microcapsules or microcups (such as electrophoresis).

[0010] There are slight differences in the production of different batches of electronic paper modules (such as particle distribution or material properties), which makes it impossible for a fixed WF to guarantee the display consistency and optimization effect of all products.

[0011] To improve the performance of electronic paper, multiple temperature points need to be set over a wide temperature range. At each temperature point, the driving waveform (WF) for each color on each display screen needs to be adjusted. In current technology, this adjustment process is performed manually, which is not only inefficient but also prone to errors. Improving testing efficiency is a key technical problem to be solved.

[0012] Definitions: WF stands for Waveform. It is a voltage-time sequence used to drive the movement of electronic paper particles. By adjusting the waveform, the display effect can be optimized. Different batches of modules require different waveforms to ensure consistency. Summary of the Invention

[0014] The technical solution of this application to solve the above-mentioned technical problems is a multi-temperature electronic paper driving waveform WF adjustment system, used to set the driving waveform parameters of the electronic paper display module, including a control module, a temperature control box, a test driving device, and an optical test module; the control module is electrically connected to the temperature control box, the control module can set the temperature of the temperature control box, and the control module can acquire the real-time temperature of the temperature control box; The control module is electrically connected to the test drive device, which in turn is electrically connected to the electronic paper display module under test. The control module is also electrically connected to the optical test module, which acquires the display image. The control module sets the test image and the initial drive waveform WF. The test drive device drives the electronic paper display module to display the image based on the drive waveform WF.

[0021] After step A10, the following steps are included: Step A20: Periodically acquire the temperature or humidity of the temperature control box; wait for the temperature or humidity of the temperature control box to equal the set value.

[0022] The temperature control chamber is set to include at least two temperatures, namely temperature A and temperature B, where temperature A is greater than temperature B; temperature A corresponds to at least two test colors, and temperature B corresponds to at least two test colors.

[0023] The test colors must include at least two of the six standard colors: red, orange, yellow, green, cyan, and purple.

[0036] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] It should be noted that the following description of preferred embodiments of this application does not constitute any limitation on this application. The description of preferred embodiments is merely an illustration of the general principles of this application. The embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the equipment or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. Furthermore, the terms "first," "second," and technical features numbered with Arabic numerals 1, 2, 3, etc., and designations such as "A" and "B," are used for descriptive purposes only, for ease of explanation, and do not represent a temporal or spatial order; they should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first," "second," and numbered with Arabic numerals 1, 2, 3, etc., may explicitly or implicitly include one or more of that feature. In the description of this application, "several" means two or more, unless otherwise expressly and specifically defined.

[0039] The key feature of electronic paper is that the image remains unchanged even when power is off; it exhibits bistable behavior. It maintains a stable state both before and after printing. This post-power-off stability allows electronic paper to perform image printing like liquid crystals, but with zero power consumption, unlike traditional paper.

[0040] Electronic paper uses a reflective display principle, just like how we see real objects. It does not emit harmful blue light, making it easy on the eyes. Thanks to these advantages, electronic paper has experienced rapid development in the flat panel display industry, leading to increasing demand.

[0041] Electronic paper consists of charged, suspended black and white spheres suspended in a colloidal solution. The charged spheres are moved by the Lorentz force generated by voltage. Due to current technological limitations, neither the colloidal solution nor the charge on the spheres can be perfectly precise. Therefore, each batch of electronic paper produced will have slight variations when driven by voltage. These variations require manual adjustment, known as WF adjustment, to ensure that each piece of electronic paper exhibits the same effect.

[0042] With increasing usage and rising color requirements, manually adjusting the color field (WF) of electronic paper would consume a significant amount of manpower. Therefore, this paper proposes a system design for automatic WF adjustment in electronic paper.

[0043] like Figure 1A multi-temperature electronic paper driving waveform WF adjustment system is used to set the driving waveform parameters of an electronic paper display module, including a control module, a temperature control chamber, a test drive device, and an optical test module.

[0044] like Figure 1 The control module is electrically connected to the temperature control box, enabling it to set and acquire the box's real-time temperature. It is also electrically connected to the test drive device, which in turn connects to the electronic paper display module under test. Furthermore, the control module is electrically connected to the optical test module, allowing it to acquire the display image. The control module sets the test image and the initial drive waveform WF. Based on the WF, the test drive device drives the electronic paper display module to display the image. If the displayed image does not match the test image, the control module adjusts the WF parameters to regenerate the image, ensuring it matches the test image. Finally, the control module writes the WF parameters into the electronic paper display module.

[0045] The connection and setup of the control module, temperature control chamber, test drive device, and optical test module enable the system to have the basic conditions for automated testing.

[0046] The driving waveform WF parameters include temperature, color, and driving waveform parameters. After system storage, each temperature and color corresponds to its own driving waveform parameters, which include signal amplitude, period frequency, and pulse timing. Detailed mappings between driving waveform data can be established.

[0047] The drive waveform WF parameters also include humidity. A library of drive waveform WF parameters under different humidity conditions can be established, enabling more accurate driving and better driving performance.

[0048] like Figure 3 and Figure 4 The optical testing module includes a camera module, which comprises a GRB color camera. The camera module connects to the control module via a USB interface. It can take color photos and debug the drive waveform of the color electronic paper. The connection between the camera module and the control module via USB is convenient and easy.

[0049] The test drive unit is electrically connected to the electronic paper display module via an FPC interface cable; the test drive unit is also electrically connected to the control module via a serial port; the control module is an industrial computer or a general-purpose computer. This facilitates test connections.

[0050] like Figure 2 and Figure 3The temperature control box connects to the control module via a serial port or Ethernet port. The box includes a temperature control module, a temperature sensor, a humidity control module, and a humidity sensor, facilitating temperature and humidity control.

[0051] like Figure 5 A method for adjusting the driving waveform (WF) of an electronic paper display module at multiple temperatures is disclosed. This method includes the following steps: A10: setting the temperature or humidity of the temperature control chamber; B10: setting the test color (Wn); C10: adjusting the electronic paper WF data; D10: using the WF data to drive and detect the color displayed on the electronic paper; E10: capturing an image of the electronic paper display and determining if the image and color match the set test color (Wn); if they match, proceed to step F10; otherwise, proceed to step C10; F10: if they match, record the correspondence between temperature / humidity, color, and WF, and write this relationship into the electronic paper display module; G10: determining if the color test is complete; if not, proceed to step A10; if complete, end the test.

[0052] like Figure 5 It can set different temperatures and colors, and adjust the WF (waveform) data of the electronic paper drive waveform at different temperatures, recording the corresponding relationships, thus completing the process from setting to data recording. When capturing images of the electronic paper display, the system has the ability to automatically identify whether the image matches the set color, thereby completing closed-loop automatic adjustment and testing.

[0053] like Figure 5 After step A10, the process includes: Step A20: Periodically acquire the temperature or humidity of the temperature control chamber; wait for the temperature or humidity of the temperature control chamber to equal the set value. It can record data corresponding to different temperatures and humidity levels.

[0054] The temperature control chamber can be set to at least two temperatures, namely temperature A and temperature B, where temperature A is greater than temperature B. Temperature A corresponds to at least two test colors, and temperature B corresponds to at least two test colors. This allows for adjustments and measurements at different temperatures, significantly improving automation capabilities.

[0055] The test colors must include at least two of the six standard colors: red, orange, yellow, green, cyan, and purple. The system can automatically perform tests under multiple colors, making it more automated.

[0056] A multi-temperature electronic paper driving waveform (WF) adjustment system and method includes a control module, a temperature control chamber, a test drive device, and an optical test module. The control module is electrically connected to the temperature control chamber, and can set the temperature of the temperature control chamber and acquire the real-time temperature of the temperature control chamber. The process involves adjusting the electronic paper WF data; using the WF data to drive and detect the color displayed on the electronic paper; capturing an image of the electronic paper display and determining whether the image and color match the set test color Wn; if they match, recording the correspondence between temperature, humidity, color, and WF, and writing the relationship into the electronic paper display module; if they match, proceeding to step F10; if they do not match, returning to the step of capturing the electronic paper display image; determining whether the color test is complete, until all set colors and temperatures are tested.

[0057] like Figure 7 The principle of the electronic paper driving waveform WF adjustment test in this application is explained as follows: When the host computer clicks "Start Automatic WF Adjustment," it sends control commands and necessary data to the driver board. The driver board then drives the electronic paper according to the data information from the host computer, providing power and data to the electronic paper. After receiving the data from the driver board, the electronic paper displays the test image. Once the electronic paper has finished displaying the test image, the host computer sends test commands to the I1 testing tool. The I1 testing tool tests the optical data of the electronic paper and feeds it back to the host computer.

[0058] Cycle 1-5. After the optical tests within the same temperature range are completed, the host computer controls the temperature control chamber to adjust the temperature. Cycle 1-6 until all temperatures and test results are adjusted, then end.

[0059] The computer-controlled commands include a drive waveform (WF) parameter, used to control the display colors of the electronic paper. Additionally, the commands also need to control the temperature chamber and the I1 testing tool.

[0060] like Figure 8 The first step is to send a command to the incubator and wait for it to reach the specified temperature. For example, set it to have 10 temperature segments. Set the first temperature segment for the first time. Once the incubator reaches the first temperature segment...

[0061] like Figure 8 Channel 1 begins controlling the WF (Color Field) data of the electronic paper. This involves a significant amount of data. Because individual electronic paper samples exhibit considerable variation, 5-10 times the number of WF samples are needed. For example, consider red for the current temperature range. Based on historical experience, there's already a WF sample for red. However, due to individual differences, the red displayed by the current electronic paper using the experienced WF sample, while still red, may show significant variations and excessive color difference, failing to meet market demands. Therefore, 5 or 10 red samples with fine-tuned WF samples are needed. Each color requires 5-10 times the number of WF samples.

[0062] like Figure 8 After sending WF data and the electronic paper displays the color, channel 2 begins controlling the I1 test command to test the current optical values ​​of the electronic paper. After the test is complete, channel 3 continues sending control WF data to the electronic paper.

[0063] like Figure 8 The process begins with a loop between channels 2 and 3. Channel 4 is used only after all color filters (WFs) for a given temperature range have been sent. For example, if the current temperature range requires 10 colors and 10 times that number of WFs (10 x 10 = 100 WFs), then channel 4 is used after all WFs for the current temperature range have been tested and all WFs for that range have been sent.

[0064] like Figure 8 Control the temperature of the constant temperature chamber to the second temperature segment. Start the loop: channel 1, channel 2, channel 3, channel 4. Continue until all temperature segments have been tested, then proceed to channel 5 to finish. If there are 10 temperature segments, then it will be 10 × 100 = 1000 WF tests before ending.

[0065] like Figure 7 The electronic paper is placed in a temperature-controlled chamber, as is the I1 testing tool. This is because the colloidal solution of the electronic paper is sensitive to temperature. Simply put, in cold weather, the colloid tends to freeze. Therefore, each temperature requires a temperature-controlled chamber (WF).

[0066] like Figure 7 I1 testing tools: The mainstream testing tool is still the I1. Some people are starting to use dedicated cameras because cameras can collect data from multiple WF effects simultaneously, improving efficiency. However, their accuracy is currently not as good as the I1. An I1 testing tool could be the i1Basic Pro 3 Plus color calibrator.

[0067] like Figure 7 The entire system revolves around the color of electronic paper. Electronic paper is sensitive to temperature. Therefore, the color adjustment of electronic paper using color rendering (WF) is strongly correlated with temperature. For example, the WF for red at 0 degrees Celsius is different from that at 5 degrees Celsius. Therefore, WF needs to be divided into temperature and color; the same color at different temperatures results in a different WF, and different colors at the same temperature also result in different WFs. Temperature and color are the two variables.

[0068] As described above, a module with 1000 WF data points requires 1000 manual adjustments to meet market requirements. This is a huge workload. However, this application allows for automated testing and adjustment, significantly improving efficiency.

[0069] This application discloses a multi-temperature electronic paper driving waveform (WF) adjustment system and method, including a control module, a temperature control chamber, a test drive device, and an optical test module. The control module is electrically connected to the temperature control chamber, and can set the temperature of the temperature control chamber and acquire the real-time temperature of the temperature control chamber. The system adjusts the electronic paper WF data; uses the WF data to drive and detect the color displayed on the electronic paper; captures an image of the electronic paper display, and determines whether the image and color match the set test color Wn; if they match, the system records the correspondence between temperature, humidity, color, and WF, and writes the relationship to the electronic paper display module; if they do not match, it returns to the step of capturing the electronic paper display image; it determines whether the color test is complete, until all set colors and temperatures are tested. This system can automatically adjust the driving waveform WF, improving production testing efficiency.

[0070] As shown in the accompanying drawings, the above are merely embodiments of the present invention and do not limit the patent scope of the present invention.
