In one embodiment, multiple temperature sensing unit may correspond to the multiple pixel cell be arranged near organic LED display panel edge, and namely temperature sensing unit can be looped around face plate edge setting, forms the structure of a temperature sense housing.In application, when user grasps edge, multiple temperature sensing unit will transmit temperature signal to control unit, and control unit just can judge that user wants to bring into use organic LED display device, now will start organic LED display panel.
In addition, if when this organic LED display panel 13 is applied in portable electric device, multiple temperature signals that these temperature sensing units also can be utilized to provide form a temperature profile, through control unit, described temperature profile and one are activated Rule of judgment comparison, when temperature profile conforms to activation Rule of judgment, organic LED display panel can receive input.Activation Rule of judgment herein can comprise manipulation quantity, manipulation distributed number, manipulation quantity pattern or its combination.
Because portable electric device must under the manipulation event matches such as manipulation quantity, manipulation time, manipulation quantity pattern or manipulation position activate the prerequisite of Rule of judgment, organic LED display panel 13 just can be allowed to receive at least one input of user's input, to carry out various control.Therefore; when there being other user operation portable electric device; then can be not identical with the activation Rule of judgment that original subscriber presets because of manipulation events such as manipulation quantity, manipulation time, manipulation quantity pattern or manipulation positions; and cannot control, and improve the user profile protection fail safe of portable electric device.
Then, the sub picture element being the organic LED display panel shown in Fig. 3 please also refer to Fig. 4 and Fig. 5, Fig. 4 arranges schematic diagram.Fig. 5 is the schematic diagram that the sub picture element shown in Fig. 4 forms sawtooth geometrical pattern.
From figure, the sub picture element Heterogeneous Permutation of the same color finding out different lines can be known, form sawtooth (zigzag) geometrical pattern to make the sub picture element of multiple same color.R in drawing represents red sub picture element, G represents green sub picture element, B represents blue sub picture element, W and then represents white sub picture element, but different application can select the sub picture element of different colours to combine, not with this drawing for restriction.Through this configuration, the present embodiment also can increase white sub picture element, therefore has the aperture opening ratio of better light transmittance and Geng Gao.If traditional RGB technology, the light transmittance of ultrahigh resolution UHD panel is only 60% of FHD, and this just needs the use increasing backlight module.But, RGBW is just without this respect problem, because it can provide better light transmittance, energy loss have also been obtained reduction.In traditional UHD panel, because sub picture element is more, therefore need enough powerful drive IC and T-Con to promote panel running.But the sub-picture element of RGBW panel is less, therefore the cost of drive IC and T-Con can be reduced.The edge of the sub picture element of adjacent different colours can be made less obvious, also can reduce the impact of moire effect, produce following comprehensive effect advantage: (1) is light transmittance better, higher aperture opening ratio; (2) energy loss is reduced; (3) cost of drive IC and T-Con (time schedule controller) is reduced; (4) use of backlight module is reduced.In addition, this kind of configuration also can improve overall resolution, manufacture craft can use traditional amorphous silicon manufacture craft, and manufacture craft is shown to improve makes cost price reduce.
In sum, the present invention arranges multiple temperature sensing unit through at organic LED display panel, and judges manipulation position and the instruction of the input of user through the temperature signal that temperature sensing unit transmits.Under this configuration, user directly must not contact organic LED display panel to complete input action, therefore the problem that the outer surface that can reduce panel is easily scraped off, the grease pointed and aqueous vapor easily attach, and improve touch-control and display life and high-resolution usefulness, promote the fine experience of use of user and price human-oriented.
The above is only illustrative, instead of restrictive.Anyly do not depart from the spirit and scope of the present invention, and to its equivalent modifications of carrying out or change, all should comprise in the appended claims.
