Description
Technical field
The utility model is a kind of touch flat display apparatus, and a kind of capacitance touching control formula of knowing image flat-panel screens that provides under high ambient light is provided especially.
Background technology
Because the flat-panel screens universalness, add that present every appliance and electronic all requires under the frivolous prerequisite of size, gradually popularize with the framework of contact panel collocation flat-panel screens, replacing, and reach the effect of simplifying as input medias such as button or mouses.
Present common contact panel generally is divided into two kinds, and one is an electric resistance touch-control panel; Another kind then is a capacitance type touch-control panel, these two kinds of contact panels all have its advantage and disadvantage, the capacitance type touch-control panel that designs in the grid electrode mode especially of condenser type wherein, each contact point is independent coordinate position, make processor identification simultaneously multipoint touch position, therefore have the multipoint operation induction and touch (Multi-Touch) effect, in addition, capacitive line loading meeting is also lighter than resistance-type line loading.
But if inquire into the visibility that is applied on the flat-panel screens, because capacitance type touch-control panel is to be formed by plural substrate, whole applying of conductive layer, and electric resistance touch-control panel upper/lower electrode layer still presss from both sides and establishes a sheaf space, non-full applying, thus when the light peneration of capacitance type touch-control panel and anti-reflective all than electric resistance touch-control panel for well.Though condenser type has above-mentioned advantage, anti-reflection effect is still not good under high light, and reflectivity and during end face, then can significantly reduce the light emission rate of display panel on being arranged at the display panel header board about about 15%, cause the unclear defective of developing.
Though partly manufacturer's discovery can be by the anti-reflective film plated film at present, reduce of the influence of external environment light to visibility, and generally speaking overall reflectivity still is more than 10%, add anti-reflective film and just improve first floor reflection problems, still can reflect as for the light that is penetrated each layer by other lower floor, and can't clearly watch image, so still remain further to be improved from the exiting surface of LCD.
Summary of the invention
For this reason, main creation purpose of the present utility model provides the visual capacitance touching control flat-panel screens of a kind of high light, and the capacitance touching control formula flat-panel screens of the low light emission rate of order can provide under the high ambient light environment clearly develops.
Desiring to reach the employed major technique means of above-mentioned purpose is to make this capacitance touching control formula flat-panel screens be made up of a capacitance type touch-control panel, a display panel and two-phase potential difference plate, wherein a polarizer is to be located at the interior Polarizer lower surface of this contact panel, and another polarizer then can be located at contact panel and display pannel junction.
The utility model major technique is that two phase differential that are 90 degree differences mutually are arranged between capacitance type touch-control panel and the display panel, when if the optical axis angle of the polaroid of this capacitance type touch-control panel is miter angle degree difference with first, second polarizer respectively, can make overall reflectivity reduce again.
The utility model time creation purpose provides a kind of flat display apparatus with higher antireflection rate, be that above-mentioned contact panel upper substrate upper surface is provided with an anti-reflective film again, overall reflectivity is reduced again, reduce of the interference of the incident ray of high brightness direct-view flat-panel screens image.
