Description
Technical field
User can be allowed to pass through polarisation the invention relates to a kind of touch control display apparatus, and in particular to one kind
The touch control display apparatus of element viewing.
Background technology
With the development of science and technology, electronic product has been widely used in daily life.In order to reach carry it is more convenient,
More humane purpose is more lightly changed and operated to volume, and many electronic products are filled by inputs such as traditional keyboards or mouse
It puts, is changed into and is inputted using touch control manner.Such as mobile phone in mobile electronic product or tablet computer etc., be touch panel with it is aobvious
Show the touch control display apparatus that panel is combined into.
In driving or movement, in order to reduce influence of the ambient to eyes, the user of touch control display apparatus can
It can wear the display picture of polarization type sunglasses viewing screen.However, the polarization direction due to image light may be with polarisation
The polarization direction of formula sunglasses is orthogonal, and user is caused to see completely black picture, and causes the inconvenience of user.In detail
It says, Figure 1A show the schematic diagram that sunglasses are used with the collocation of general touch control display apparatus.Please refer to Fig.1 A, touch-control display dress
It puts 100 and includes display panel 110 and touch panel 130.Display panel 110 is to show image, and display panel 110 has
There is upper polarizer 112, upper polarizer 112 has penetrating shaft (not shown).When user wears polarization type sunglasses G with different
During viewing angle θ touch control display apparatus 100, since the display image of touch control display apparatus 100 belongs to linear polarization, use
The brightness that person is seen can have notable difference as polarization type sunglasses G viewing angles θ is different.Figure 1B show touch-control and shows
The light distribution of angle change folded by showing device and polarization type sunglasses G is as a result, please refer to Fig.1 B, in wearing for upper polarizer 112
In the case that angle between axis and polarization type sunglasses G is about 150 degree or 330 degree thoroughly, touch-control that user is seen
Display device is substantially without brightness.
Traditionally it can will show image by the way of one layer of quarter-wave plate additionally is configured on a display panel
Linear polarization is converted to circular polarization state, and avoid user wear polarization type sunglasses come when watching touch control display apparatus not
There are problems that brightness disproportionation with angle.Existing such touch control display apparatus at present is simply introduced below.
Fig. 2A show the diagrammatic cross-section of the existing touch control display apparatus of one of which.Fig. 2A is please refer to, touch-control is shown
Showing device 200a includes backlight module 240a, liquid crystal display panel 210a, quarter-wave plate 220a and the touch-control of sequential

212a.Quarter-wave plate 220a is configured between upper polarizer 212a and touch panel 230a.
Fig. 2 B show the diagrammatic cross-section of another existing touch control display apparatus.Please refer to Fig.2 B, touch-control display dress
Put organic light emitting display panel 210b, quarter-wave plate 220b and cover board 230b that 200b includes sequential.Organic hair
The organic light emitting display layer 214b that light display panel 210b further includes sequential (has integrated/in-building type (on-cell/
In-cell) touch-control module), lower quarter-wave plate 216b and upper polarizer 212b.
Above two touch control display apparatus is to convert the light of linear polarization through quarter-wave plate 220a, 220b
For circular polarization state, so that light is roughly the same in the component of each polarization direction, and improves user and wear polarization type sun eye
When watching touch control display apparatus there is brightness disproportionation in different angle in mirror.However, above-mentioned touch control display apparatus is equal
One layer of quarter-wave plate need to additionally be configured, and so that the thickness of touch control display apparatus is difficult to reduce, do not meet electronics production now
The light and short trend of product.
