Description

Technical Field

[0001] The utility model relates to the technical field of display modules, in particular to an eye protection display module. Background Art

[0002] Consumers have higher and higher requirements for the convenience of electronic products. Long battery life and use anytime and anywhere have become the basic requirements of consumers for product performance. Eye protection, low power consumption and high battery life have become a major demand for electronic products. Especially at this stage, teaching relies on interactive electronic products. Compared with paper and abstract text descriptions, the powerful functions of electronic products can better promote teaching effects, but at the same time, electronic products are also very harmful to the eyes. At the same time, insufficient battery life also brings a lot of inconvenience to teaching work.

[0003] Existing displays with touch functions mainly display images through LED and OLED light; LED, or light-emitting diode, is a semiconductor light-emitting device; LED converts point light sources into surface light sources through light guide plates, and uses reflective sheets to reflect the light leaking from the bottom back to the light guide plate for reuse, so as to increase the efficiency of light use; finally, the light passes through the acrylic ball inside the diffusion film, and the rough surface or diffusion particles refract and scatter it, homogenizing the light to achieve a uniform and soft light effect, which is used to provide light source for the display screen, so that the picture is transmitted to the human eye through light.

[0004] OLED luminescence refers to an OLED screen that can emit light by itself. Each pixel of an OLED screen is a light-emitting diode made of organic compounds. When current passes through these light-emitting diodes, the organic material emits light.

[0005] The light emitted by LED and OLED is harmful to human eyes in two ways:

[0006] 1. Blue light hazards: The light emitted by LED and OLED may contain excessive blue light, which can penetrate the lens to reach the retina, causing myopia, visual fatigue, insomnia, etc.

[0007] 2. Hazards of flicker: The light emitted by LED and OLED may produce flicker, which may cause health problems such as eye fatigue, headache, and decreased vision.

[0008] In addition, whether it is LED or OLED light emission, there will be a certain amount of power consumption loss, and the power consumption required for light emission in the entire electronic display product accounts for as much as about 15% of the entire product, and the product battery life is short. Summary of the invention

[0009] The utility model provides an eye protection display module for the problems of the prior art. The design is ingenious and the display content can be read by using a reflective material layer. The utility model can greatly improve the endurance of display electronics and also greatly reduce the damage of display products to human eyes.

[0010] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0011] The utility model provides an eye protection display module, which includes an end cover plate, a sensor, a light guide plate, a glass cover plate and a glass circuit substrate which are arranged in sequence from top to bottom, an electronic ink particle layer is arranged between the glass cover plate and the glass circuit substrate, a first OCA layer is connected between the end cover plate and the sensor, a second OCA layer is connected between the sensor and the light guide plate, a third OCA layer is connected between the light guide plate and the glass cover plate, the upper end surface of the glass cover plate is coated with a reflective material layer, and the eye protection display module also includes a black shading tape, which is coated on the outer peripheral wall of the light guide plate, the outer peripheral wall of the glass cover plate, the outer peripheral wall of the third OCA layer, the outer peripheral wall of the electronic ink particle layer, the outer peripheral wall of the glass circuit substrate and the lower end surface of the glass circuit substrate.

[0012] Preferably, the upper end of the black light-shielding tape is attached to the outer edge of the upper end surface of the light guide plate; the distance between the upper end edge of the black light-shielding tape and the edge of the upper end surface of the light guide plate is 0.8 mm.

[0013] Preferably, the thickness of the end cover plate is 0.4 mm; the end cover plate is a PMMA composite material.

[0014] Preferably, the sensor is a capacitive sensor, the thickness of the sensor is 0.14 mm; the sensor is composed of two films.

[0015] Preferably, the thickness of the first OCA layer is 0.1 mm.

[0016] Preferably, the second OCA layer has a thickness of 0.1 mm to 0.175 mm.

[0017] Preferably, the thickness of the third OCA layer is 0.175 mm.

[0018] Preferably, the glass cover plate has a thickness of 0.25 mm.

[0019] Preferably, the thickness of the side after being coated with the black light-shielding tape is 0.03 mm.

[0020] Beneficial effects of the utility model:

[0021] The utility model has a novel structure and ingenious design. When the utility model is working, the picture can be displayed normally without lighting the product light source in an environment with external light source, and low power consumption is achieved when the displayed picture does not change. In a dark or insufficiently lit environment, the light guide plate can be lit to realize picture reading through the principle of light reflection. In our daily life environment, there is an external light source most of the time. Most of the time, there is no need to light the light guide plate. The display content can be read using the reflective material layer.
