Embodiment
For the ease of understanding the utility model, with reference to relevant drawings the utility model is described more fully below.Provided preferred embodiment of the present utility model in the accompanying drawing.But the utility model can be realized with many different forms, be not limited to embodiment described herein.On the contrary, provide the purpose of these embodiment be make to disclosure of the present utility model understand comprehensively thorough more.
Need to prove that when element is called as " being fixed in " another element, can directly can there be element placed in the middle in it on another element or also.When an element is considered to " connection " another element, it can be to be directly connected to another element or may to have element placed in the middle simultaneously.Term as used herein " vertical ", " level ", " left side ", " right side " and similar statement do not represent it is unique embodiment just for illustrative purposes.
Unless otherwise defined, the employed all technology of this paper are identical with the implication that belongs to those skilled in the art's common sense of the present utility model with scientific terminology.Employed term is not intended to be restriction the utility model just in order to describe the purpose of specific embodiment in instructions of the present utility model herein.Term as used herein " and/or " comprise one or more relevant Listed Items arbitrarily with all combinations.
See also Fig. 1, the liquid crystal indicator 100 of present embodiment comprises display panels 110 and capacitance touch screen 120.
Transparent diffuse reflector 123 is located between cover plate 121 and the display panels 110, and transparent diffuse reflector 123 is uneven surface near the surface of display panels 110.
Specifically in the present embodiment, transparent diffuse reflector 123 is organic polymer layer.For example: PET(polyethylene terephthalate, polyethylene terephthalate) etc.Because the organic macromolecule diameter is bigger, when ray cast arrived organic polymer layer, then the surface of organic polymer layer was for light, and the surface of organic polymer layer is smooth surface heterogeneous, make light generation diffuse reflection, coherent source is reflected into irregular natural light.
Be appreciated that transparent diffuse reflector 123 can also be the diffuse reflector of being made up of multiple size, particle in irregular shape.For example: circle, triangle etc.And, according to the material difference of transparent diffuse reflector 123, use diverse ways that transparent diffuse reflector 123 is located on the capacitance touch screen 120.For example, when the material of transparent diffuse reflector 123 is liquid, then can transparent diffuse reflector 123 be located on the transparent sensing layer 122 by the mode of coating.When the material of transparent diffuse reflector 123 is flexible material, then can transparent diffuse reflector 123 be sticked on the transparent sensing layer 122 by the mode that pastes.
Specifically in the present embodiment, transparent diffuse reflector 123 is located between transparent sensing layer 122 and the display panels 110.
The light of the backlight of display panels 110 is through display panels 110, and light passes from the slit between many first sense lines 111, and the slit between the second sense line 122a penetrates.Transparent diffuse reflector 123 is located between transparent sensing layer 122 and the display panels 110 transparent diffuse reflector 123 to be located between transparent sensing layer 122 and the display panels 110.After the slit of light between many first sense lines 111 passes, namely be incident upon on the transparent diffuse reflector 123, make light generation diffuse reflection, interfere phenomenon after avoiding light through the second sense line 122a.In this process, in the uneven surface of ray cast on transparent diffuse reflector 123, scattering can take place in light, to destroy one of pacing items that two-slit interference produces, namely destroys the coherent source (frequency is identical, and direction of vibration is parallel) that two-slit interference takes place.Destroy the coherence of light source, can avoid taking place two-slit interference, improve the display effect of liquid crystal indicator 100.
And the surface of base material is rough surface.Diffuse reflection takes place in ray cast equally on base material, destroy the coherent source of two-slit interference, further avoids the generation of interference.
Therefore, by using above-mentioned liquid crystal indicator 100, at OGS(One glass solution) in the type capacitance touch screen 120, can overcome the optical interference striped that produces after OGS type capacitance touch screen 120 superposes with display panels 110 display devices such as grade, make the OGS product can enter commercialization, produce bigger economic benefit.
See also Fig. 2, in other embodiments, transparent diffuse reflector 223 is located between cover plate 221 and the transparent sensing layer 222, light is during through the slit between the second sense line 222a, project on the transparent diffuse reflector, make light generation diffuse reflection, avoid producing interference.
Be appreciated that between cover plate and the display panels to be provided with the multi-layer transparent diffuse reflector, increase the diffuse effect of light, further prevent from forming coherent source, to avoid interfering phenomenon, improve the display effect of liquid crystal indicator 100.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
