Technical field
The present invention relates to the display device and its method field of manufacturing of a kind of reflection-type for having colour filter, in particular to one
The structure and manufacturing method of kind color display module.
Background technique
As the electronic media of replacement paper, the exploitation of the display device of Electronic Paper etc. is just energetically carried out.Relative to conduct
CRT, the liquid crystal display of the display of previous type, Electronic Paper etc. are mainly used and have been used by structures such as white particles, black particles
At the display mode of reflection-type of display medium it is necessary to have high white reflectivities, high contrast, it is in addition to this, also uncommon
Hoping is had the memory effect for shown image, can be driven with low-voltage, is thin and light and cheap etc..It is special
It is not the white reflectivity and/or contrast with paper homogeneity to be required as display characteristic, in addition, previous paper delivery medium is natural
Full-color display is carried out, therefore very high for the expectation of the colorization of the display device of Electronic Paper etc..
In the technology proposed so far, as the Electronic Paper for being able to carry out colored display, formed in liquid crystal cell
There is the commercialization such as Electronic Paper of colour filter, but because they use polarizer, the utilization efficiency of light is low, Zhi Nengjin
Row is than darker white displays.In addition, contrast is also poor because black can not be shown.
In addition, as polarizer, bright reflection display device is not used, it is known to electrophoretic, the electrophoretic
Principle be moved by electric field electrification come white particles and black particles.Generally, it may be said that be based on the electrophoretic
Scattered reflection rate it is most less than 40%, currently wish to further increase reflection efficiency.In particular, when carrying out colored displayization
When, due to the absorption based on color layer, the utilization efficiency decline of light, just energetically researches and develops bright technicolo
Sub- paper.
Existing solution is recorded in following patent:
Prior art 1:CN201180028037.X- Electronic Paper colour display device and its manufacturing method；
Prior art 2:CN201110430449.8- color electronic paper and its manufacturing method；
But since Electronic Paper itself does not shine, therefore the brightness of the colorful display screen of traditional technology means is inadequate, only logical
The scheme of light before increasing is crossed to overcome, but it is partially dim and existing aobvious to will lead to color because of the reflex of colored filter in this way
Show that module thickness is too thick.
Summary of the invention
It is an object of the invention to: the structure and manufacturing method of a kind of color display module are provided, is solved due to electricity
Sub- hard copy body does not shine, therefore the brightness of the colorful display screen of traditional technology means is inadequate, only by increase before light scheme come
Overcome, but in this way because of the reflex of colored filter, will lead to that color is partially dim, and existing display module thickness is too thick asks
Topic.
