Specific embodiment
It is with reference to the accompanying drawings and embodiments, right in order to which the objects, technical solutions and advantages of the application are more clearly understoodThe application is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain the application, andIt is not used in restriction the application.
In the description of the present application, it is to be understood that term " center ", " transverse direction ", "upper", "lower" "left", "right",The orientation or positional relationship of the instructions such as "vertical", "horizontal", "top", "bottom", "inner" and "outside" is side based on the figurePosition or positional relationship are merely for convenience of description the application and simplify description, rather than the device or member of indication or suggestion meaningPart must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as the limitation to the application.ThisOutside, it should be noted that when element is referred to as " being formed on another element ", it can be directly connected on another element orPerson may be simultaneously present centering elements.When an element is considered as " connection " another element, it be can be directly connected to separatelyOne element exists simultaneously centering elements.On the contrary, there is no centres when element is referred to as " directly existing " another element "upper"Element.
It as described in background, can be by display screen due to needing the photosensitive elements such as integrated front cameraFront camera and infrared inductor etc. is arranged in slot area in upper fluting.This way actually slot area is stillNon-display area, so as to cause can not really realize screen display comprehensively.Based on the above issues, this department has applied for a kind of display screen,It realizes comprehensive screen display of electronic equipment in the mode of slot area setting transparent display panel.But due to slot areaDisplay panel and other regions display panel driving method and device architecture have differences, cause to produce between each otherRaw interference, so that display screen will appear the problem of can not normally showing.Even the display panel of slot area and otherThe display panel in region uses identical panel construction, mutually does also due to the difference of driving method causes to exist therebetweenIt disturbs, display screen is caused to will appear the problem of can not normally showing.
For example, when slot area uses PMOLED display panel, and other regions (namely non-slotted region) are AMOLEDWhen display panel, since PMOLED display panel is the driving method of " current mode+row scanning ", the level one of line scan signalsAs in the case of in 10V or more, frequency is in 10KHz or more, and the level of cathodic scan signal (namely column scan signal) is generalIn 8V or so, frequency is in 100Hz~200Hz；And the driving method of AMOLED display panel is voltage-type driving method, drivingThe voltage of voltage is in 6V or so, and the distance between two display panels are in the micron-scale, therefore the frame frequency of PMOLED display panelThe timing of AMOLED can all be interfered with line-frequent signal, AMOLED display panel is caused not show normally, so thatEntire display screen can not normally be shown.
In order to solve the above technical problems, one embodiment of the application provides a kind of display screen, can well solveState problem.Fig. 1 is the structural schematic diagram of the display screen in an embodiment.Referring to Fig. 1, which has the first viewing area AA1With the second viewing area AA2.First viewing area AA1 and the second viewing area AA2 is connected with each other.In one embodiment, the second viewing areaAA2 can be set in the top center region of display screen, so that there are three face contacts with the first viewing area AA1, as shown in Figure 1.In other examples, the second viewing area AA2 also can be set in the side of display screen, and the first viewing area AA1 is then arrangedThe other side of display screen.For example, the second viewing area AA2 and the first viewing area AA1 are sequentially distributed along the length direction of display screen, orPerson is sequentially distributed along the width direction of display screen.At this point, the first viewing area AA1 and the second viewing area AA2 only has one side to connect.?In Fig. 1, the quantity of the first viewing area AA1 and the second viewing area AA2 are one, in other examples, the first viewing areaThe quantity of AA1 and the second viewing area AA2 all can be two or more.First viewing area AA1 and the second viewing area AA2It is used to display dynamically or statically picture.
