Abstract
The utility model discloses an improved structure of an e-book LED backlight source. The structure comprises an ABS plastic support, a PMMA lens arranged at the upper end of the ABS plastic support and an LED display screen distributed on the lower portion of the PMMA lens. An LED illuminating lamp assembly is arranged in a groove between the ABS plastic support and the PMMA lens, and the inclined angle between the PMMA lens and the LED display screen is 10-30 degrees. Due to the fact that the inclined angle between the PMMA lens and the LED display screen is 10-30 degrees, according to the optical principle of LED side luminescence, light rays from an LED light source are uniformly reflected on the LED display screen through the PMMA lens, the backlight problem that a self-luminous ink display screen of an e-book does not exist is solved, customers can clearly read words on a display screen of the e-book in the situation that lamps are not available at night or lamp light is dim, and time requirements for pursuits of knowledge and spiritual fields of people are met.
Description
Technical field
The utility model relates to a kind of e-book LED-backlit source and improves structure.
Background technology
Modern's living standard is more and more higher, and the cultural demand aspect realm of spirit is desired height gradually, and Read book becomes the common a kind of life style of consumer.Along with the innovation of development of science and technology technology, stating of each side such as environmental protection concept asked, and the rhythm of digital industry is also accelerated.Coincide people's life requirement of the emerging of E-ink electricity paper book.E-ink adopts ink display technology, and principle of reflection manifests content, and it has, as the visual effect of true paper, and its flicker free is radiationless, does not hinder eye, is fit to read for a long time under daytime and the high light, and each side such as its environmental-friendly and comfortable are liked by the consumer deeply.But " do not have self luminous ink display screen " and " traditional LC D autoluminescence liquid crystal display " contrast, its inferior position is: the pictograph that can not cannot see " ink display screen " by secondary light source at night.
Summary of the invention
Technical problem to be solved in the utility model provides a kind ofly need not just can improve structure in the e-book LED-backlit source that read night by secondary light source.
The utility model is achieved through the following technical solutions: structure is improved in a kind of e-book LED-backlit source, comprise the ABS plastic rubber bracket, and be installed in the PMMA eyeglass of ABS plastic rubber bracket upper end, and be arranged in the LED display of PMMA eyeglass below, LED electroluminescent lamp assembly is installed in the groove between described ABS plastic rubber bracket and the PMMA eyeglass, described PMMA eyeglass reflective surface is printed on the black silk-screen, described PMMA eyeglass and LED display are 10 ° to 30 ° angle of inclination, form a gap between described LED electroluminescent lamp assembly and the PMMA eyeglass bottom surface.
As optimized technical scheme, described LED electroluminescent lamp assembly is arranged on by black silk-screen one end.
The beneficial effects of the utility model are: the utility model utilizes PMMA eyeglass and LED display to be 10 ° to 30 ° angle of inclination, utilize the luminous optical principle of LED side, evenly be reflected in led light source on the LED display by the PMMA eyeglass, solved the problem backlight of " the ink display screen of no autoluminescence e-book ", make its consumer not have under the situation of lamp at night or also can clearly see literal on the e-book display screen under the situation that the light is dusky, people have been satisfied to the time point of knowledge to the pursuit of realm of spirit, extend to night by reading on before daytime, people's aspiration to knowledge and persistent degree etc. are had immortal value.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the vertical view that structure is improved in the utility model e-book LED-backlit source;
Fig. 2 is the structural representation at A-A place among Fig. 1;
Fig. 3 is the partial enlarged drawing at B place among Fig. 2;
Fig. 4 is the structure explosive view that structure is improved in the utility model e-book LED-backlit source.
Embodiment
As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, structure is improved in a kind of e-book LED-backlit of the present utility model source, comprise ABS plastic rubber bracket 2, and be installed in the PMMA eyeglass 4 of ABS plastic rubber bracket 2 upper ends, and be arranged in the LED display 1 of PMMA eyeglass 4 belows, LED electroluminescent lamp assembly 3 is installed in the groove between described ABS plastic rubber bracket 2 and the PMMA eyeglass 4, described PMMA eyeglass 4 reflective surfaces are printed on black silk-screen 5, described PMMA eyeglass 4 is 10 ° to 30 ° angle of inclination with LED display 1, forms a gap between described LED electroluminescent lamp assembly 3 and PMMA eyeglass 4 bottom surfaces.
Wherein, described LED electroluminescent lamp assembly 3 is arranged on by black silk-screen 5 one ends.
PMMA eyeglass 4 is 10 ° to 30 ° angle of inclination with LED display 1, utilizes the luminous optical principle of LED side, by PMMA eyeglass 4 led light source evenly is reflected on the LED display 1.
The beneficial effects of the utility model: the utility model has solved the problem backlight of " the ink display screen of no autoluminescence e-book ", make its consumer not have under the situation of lamp at night or also can clearly see literal on the e-book display screen under the situation that the light is dusky, people have been satisfied to the time point of knowledge to the pursuit of realm of spirit, extend to night by reading on before daytime, people's aspiration to knowledge and persistent degree etc. are had immortal value.
The above only is embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
