Problems solved by technology

But everyone's eyes feel differently about light. When reading, some people feel comfortable with the same color of light, while others feel uncomfortable or dazzling.
In this way, because the color of the light source cannot be changed, it cannot meet the different needs of everyone.

Embodiment 1

[0040] refer to Figure 1-3 , figure 1 It is a schematic longitudinal cross-sectional view of an electronic paper display device with a light source in the first embodiment of the present invention; figure 2 for figure 1 A transverse cross-sectional view of an electronic paper display device with a light source; image 3 for figure 1 A circuit schematic diagram of an electronic paper display device with a light source.

[0041] In this embodiment, an electronic paper display device with a light source includes an electronic paper display module 101 , a first transparent optical glue 102 , a light guide plate 103 , and a front light source group 104 .

[0042] The electronic paper display module 101 is an electrophoretic display module, and the electrophoretic display module is printed on a certain substrate by electronic ink of a liquid material. In this liquid material, hundreds of microcapsules about the size of a human hair are suspended, and each microcapsule is comp...

Embodiment 3

[0055] Figure 5 It is a schematic longitudinal cross-sectional view of an electronic paper display device with a light source in the third embodiment of the present invention; Image 6 for Figure 5 A transverse cross-sectional view of an electronic paper display device with a light source.

[0056] This embodiment may be an improvement on the basis of Embodiment 1 or Embodiment 2, and an anti-reflection and anti-glare protective film 108 is added on the basis of Embodiment 1 or Embodiment 2. That is, a replaceable anti-reflection and anti-glare protective film 108 is directly pasted on the light guide plate 103 . The anti-reflection and anti-glare protective film 108 can reduce reflection and allow more light to enter; at the same time, it can prevent specular reflection and improve reading effect; in addition, it can protect the light guide plate from being scratched.

Embodiment 4

[0058] Figure 7 It is a schematic longitudinal cross-sectional view of the fourth embodiment of an electronic paper display device with a light source according to the present invention. This embodiment can be an improvement on the basis of Embodiment 3. On the basis of Embodiment 3, a second transparent optical glue 109 is added, and the anti-reflection and anti-glare protective film 108 is glued by the second transparent optical glue 109. Attached to the light guide plate 103, it can prevent the anti-reflection and anti-glare protective film 108 from falling off or warping. The second transparent optical adhesive 109 can be made of solid OCA or liquid OCA optical clear adhesive (Optical Clear Adhesive) material. The second transparent optical adhesive 109 requires better light transmission performance.

Abstract

The invention relates to an electronic paper display device with a light source. The device comprises an electronic paper display module, guide plates arranged close to the periphery of the electronic paper display module and a front light source set arranged close to the side faces of the guide plates, wherein the front light source set comprises light source units with two or more than two different colors and/or color temperatures and a driving circuit driving the light source units; and the light source units with different colors and/or color temperatures are arranged in a cross manner. Therefore, the user can select the light source units with different colors according to different demands to read, so that the selectable range of light colors can be expanded to meet demands of different people so as to improve the reading effect.

Description

technical field [0001] The invention relates to an electronic paper display device, in particular to an electronic paper display device with a light source. Background technique [0002] Electronic paper technology is actually a general term for a class of technologies. The English name is E-paper, and most of them use electrophoretic display technology (electrophoresis display, EPD) as the display panel. The electronic paper display device is different from the emanating display device. The emanating display device can emit light by itself, so it can be used normally even in dim light conditions. However, as the intensity of ambient light increases, the display effect of this diffuse display is not so satisfactory, because the strong ambient light increases the brightness of the melanin and reduces the contrast, which is also what we cannot do in direct sunlight. The reason for seeing the text on the display clearly. The reflective display displays images by reflecting am...
