Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic paper technology, and in particular to an electronic paper detection device. Background Technology
[0002] In the field of electronic display technology, the production quality control of display modules always relies on precise optical parameter measurements. In traditional processes, electronic paper waveform tuning must use spectrophotometers to obtain Lab color space data as the core evaluation indicator. However, the electric field response characteristics of electronic paper materials are significantly affected by temperature, resulting in the need for independent tuning of the corresponding drive waveform parameters for each temperature range (e.g., every 10°C interval within the range of -20°C to 80°C).
[0003] The existing debugging process requires placing the display module in a temperature chamber for environmental simulation. Once the product reaches the set temperature, it must be immediately removed from the temperature chamber for optical measurement.
[0004] However, repeated picking and putting in the equipment increases the operation time significantly and reduces efficiency; opening the chamber door disrupts the uniformity of the temperature field inside the chamber, requiring additional time to restore thermal equilibrium; when measuring outside the chamber, sudden changes in ambient temperature cause changes in the state of the electronic paper diaphragm, resulting in distortion of the measurement data compared to the actual working conditions. Utility Model Content

[0011] The detection element is used to emit detection light rays, and the detection light rays are transmitted to the electronic paper module through the intermediate element. The partially reflected detection light rays are transmitted back to the detection element through the intermediate element.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0031] Please see the appendix Figure 1This embodiment relates to an electronic paper detection device, which includes an insulated box 1, a detection element 2, and an intermediate element 3. The insulated box 1 has a receiving chamber 11 for placing an electronic paper module 100, and the receiving chamber 11 is temperature-regulating. The detection element 2 is located outside the insulated box 1 and is used to detect the electronic paper module 100. One end of the intermediate element 3 is connected to the detection element 2, and the other end extends into the receiving chamber 11. The detection element 2 emits detection light, which is transmitted to the electronic paper module 100 through the intermediate element 3, and partially reflected detection light is returned to the detection element 2 through the intermediate element 3.
[0032] Specifically, the insulated box 1 has a cubic box structure with an internal receiving chamber 11. The built-in heating system of the insulated box 1 allows for setting a temperature value as needed, ensuring that the space in the receiving chamber 11 can quickly reach the set temperature. In this embodiment, the insulated box 1 can adopt an existing structure; the specific structure and heating / insulation principle of the insulated box 1 will not be further elaborated here. The detection component 2 uses an i1Pro3 spectrophotometer. The spectrophotometer contains a monochromator and a detector. Partially reflected detection light enters the monochromator, where the dispersed composite light is decomposed into monochromatic light. The monochromatic light passes through the detector sequentially, and the LAB value is calculated using an algorithm. The intermediate component 3 uses an optical fiber tube to form the emitted and reflected light paths, ensuring the effective round-trip of the detection light.
[0033] This electronic paper testing device effectively avoids operators repeatedly picking up and putting down the electronic paper module 100, reducing manual operation steps; it also avoids the need to open and close the door of the insulation box 1, which would cause temperature changes and require additional time for the temperature field of the insulation box 1 to recover thermal equilibrium, thus effectively improving testing efficiency; at the same time, it further solves the problem of sudden changes in the environment when the electronic paper module 100 is removed from the box for measurement, which causes changes in the state of the electronic paper module 100 and distortion of the measurement results.
[0034] The main working steps of this electronic paper testing device include: First, after refreshing the electronic paper module 100 to be tested to the screen to be tested, it is placed in the receiving chamber 11 of the heat preservation box 1. Then, the operator inputs the preset temperature value. After a certain heating time, the heat preservation box 1 reaches the preset temperature value and is kept warm for a certain time to raise the temperature of the electronic paper module 100 to the ambient temperature. Then, the testing component 2 is activated and a testing light is emitted to the intermediate component 3. The testing light is transmitted to the display screen of the electronic paper module 100 through the intermediate component 3, and some of the reflected testing light is transmitted back to the testing component 2 through the intermediate component 3.
[0035] Optionally, the middleware 3 is a flexible body.
[0036] In this embodiment, the intermediate component 3 is a flexible optical fiber tube. This flexible optical fiber tube can move to adapt to changes in the position of the electronic paper module 100, ensuring that the screen of the electronic paper module 100 in the insulation box 1 is always directly facing the other end of the intermediate component 3. This guarantees that the reflected detection light is essentially transmitted back to the detection component 2 through the optical fiber tube.
[0037] Furthermore, the other end of the middleware 3 is attached to the screen of the electronic paper module 100.
[0038] By attaching the other end of the intermediate component 3 to the screen of the electronic paper module 100, it can be ensured that the reflected detection light is completely transmitted back to the detection component 2 through the fiber optic tube, thus avoiding detection distortion.
[0039] Optionally, the detection element 2 has a transmitting end 21, which is connected to one end of the intermediate element 3, and the transmitting end 21 is used to emit detection light. The detection element 2 also has a detection end 22, which is connected to one end of the intermediate element 3, and the detection end 22 is used to detect the returned detection light. The transmitting end 21 and the detection end 22 are arranged side by side.
[0040] In this embodiment, the transmitting end 21 and the detecting end 22 are used to process the emitted and returned detection light rays, respectively, to ensure the accuracy and stability of the LAB value output by the detection element 2. Furthermore, by arranging the transmitting end 21 and the detecting end 22 side-by-side, the same intermediate element 3 can be accommodated at its end, resulting in a smaller radial dimension of the intermediate element 3. This avoids increasing the size of the intermediate element 3 or using two separate intermediate elements 3 for transmission and transmission, ensuring the overall structure remains compact.
[0041] Optionally, the cavity 11 is provided with a testing platform 12, which has mounting positions for accommodating multiple electronic paper modules 100.
[0042] In this embodiment, the detection platform 12 provides mounting positions for limiting the electronic paper module 100. These mounting positions can be recesses or protrusions, ensuring accurate positioning of the electronic paper module 100 within the receiving chamber 11. Furthermore, multiple mounting positions on the same detection platform 12 allow for the arrangement of multiple electronic paper modules 100 at the same detection temperature, effectively improving space utilization and detection efficiency.
[0043] Furthermore, the other end of the intermediate component 3 is movably disposed within the receiving chamber 11.
[0044] Specifically, the receiving chamber 11 contains multiple electronic paper modules 100. By sequentially adjusting the position of the intermediate component 3 to the corresponding electronic paper module 100, multiple electronic paper modules 100 can be sequentially tested, improving flexibility and adaptability, and avoiding manual intervention and interference with accuracy. Specifically, the receiving chamber 11 is equipped with a robotic arm, which can be electrically or hydraulically driven. The actuator end of the robotic arm grips or holds the other end of the intermediate component 3 to ensure the accuracy and convenience of position adjustment.
[0045] In this embodiment, the robotic arm can also be conventionally integrated into the receiving chamber 11 to achieve convenient maintenance and replaceability.
[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
