Detailed Description
In order to make the above objects, features and advantages of the present application more comprehensible, embodiments accompanied with figures are described in detail below.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, but the present application may be practiced in other ways other than those described herein, and persons skilled in the art will readily appreciate that the present application is not limited to the specific embodiments disclosed below.
Next, the present application will be described in detail with reference to the schematic drawings, wherein the cross-sectional views of the device structure are not to scale for the sake of illustration, and the schematic drawings are merely examples, which should not limit the scope of protection of the present application. In addition, the three-dimensional dimensions of length, width and depth should be included in actual fabrication.
The current display technology field is mainly divided into liquid crystal display (liquid crystal display, LCD), organic Light Emitting Display (OLED) and Micro light emitting diode (Micro-LED) display. The liquid crystal display has the advantages of light weight, energy saving, no radiation and the like, and is widely applied to various electronic devices.
With the rapid development of terminal devices, higher demands are being put on the display of the terminal devices. Especially for different application scenarios of the terminal device, there are different requirements for the display of the terminal device, such as for application scenarios with a wide viewing angle, the larger the viewing angle of the display panel, the more the user can see the complete and undistorted picture of the display panel from all directions. For example, for a more private application scenario, the user wants to protect the information displayed by the terminal device, and the viewing angle of the display panel is smaller.
For liquid crystal display, referring to fig. 1, currently, a vertical electric field E is formed by additionally setting a full-area color film indium tin oxide (CF-ITO) in a display panel and applying voltages to the CF-ITO, a display electrode (Pixel) and a common (Com) electrode, and the electric field direction of the vertical electric field E is vertical to the direction of the plane where the CF-ITO is located, so that the liquid crystal in the display panel is tilted, that is, the liquid crystal molecule axis in the display panel and the horizontal direction of the plane where the CF-ITO is located have a certain angle, and the specific tilt angle is determined according to the electric field intensity of the vertical electric field E, that is, according to the applied voltages, the liquid crystal is tilted to cause light leakage in a strabismus dark state, the contrast is reduced, the viewing angle is reduced, and a narrow viewing angle is formed, thereby meeting the privacy scene requirement of a user. However, since the polarities of electrodes of the CF-ITO are the same across the whole area and the polarities of the electrodes of the odd-even columns of the display electrodes are different, the electric field strengths of the vertical electric fields E formed by the odd-even columns are different, and the deflection angles of the liquid crystals of the odd-even columns are different, which results in the problem of uneven display of the display panel. In addition, when the electrode polarity of the entire CF-ITO is reversed, the entire CF-ITO is reversed at the same time, that is, the polarities of the odd and even column electrodes are the same, and when the electrode polarity of the display electrode is reversed, the polarities of the odd and even column electrodes are different, that is, the entire CF-ITO cannot be reversed as the display electrode, and a flicker problem is caused when the polarities are reversed.
Based on this, the embodiment of the application provides a display panel, the display panel includes a plurality of display modes, and a plurality of display modes include first display mode and second display mode, and the display panel includes: the display device comprises a first substrate and a second substrate which are oppositely arranged, wherein a plurality of display electrodes are arranged on one side, close to the second substrate, of the first substrate, a plurality of adjustment electrodes are arranged on one side, close to the first substrate, of the second substrate, a first adjustment voltage is applied to the adjustment electrodes to obtain a second display mode, a first display voltage is applied to the display electrodes to obtain target brightness, the target brightness is the brightness of the first display mode for display, that is, the adjustment voltage is applied to the adjustment electrodes to realize the switching among the plurality of display modes, the display voltage is applied to the display electrodes to realize the adjustment of the brightness of the display panel, and the brightness of the first display mode can still be realized when the second display mode is realized by applying the first adjustment voltage to the adjustment electrodes. Therefore, the display panel provided by the embodiment of the application is provided with the first substrate and the second substrate, the first substrate and the second substrate are respectively provided with the plurality of display electrodes and the adjusting electrodes, so that the switching among a plurality of display modes is realized, different display modes can be applied to different application scenes, the brightness adjustment among different display modes can be realized by utilizing the display electrodes, and various requirements of users are met.
For a better understanding of the technical solutions and technical effects of the present application, specific embodiments will be described in detail below with reference to the accompanying drawings.
Referring to fig. 2, a schematic structural diagram of a display panel according to an embodiment of the present application is shown. Fig. 3 is a schematic cross-sectional structure along the BB direction shown in fig. 2 according to the embodiment of the present application.
The display panel provided by the embodiment of the application can be a liquid crystal display panel, and the liquid crystal display panel displays images by utilizing the optical anisotropy and birefringence characteristics of liquid crystal molecules. In the liquid crystal display panel, two substrates are disposed opposite to each other, electrodes for generating an electric field are formed on surfaces of the oppositely disposed substrates, a liquid crystal material is injected between the substrates, and then an electric field is generated by applying a voltage to the electrodes on the surfaces of the substrates to change an arrangement direction of liquid crystal molecules, so that light transmission amounts of the two substrates can be controlled, thereby obtaining an image desired to be displayed. The liquid crystal display panel generally uses a Thin Film Transistor (TFT) as a switching element.
In the embodiment of the present application, the display panel 100 includes a display area AA and a non-display area NA. The non-display area NA surrounds the display area AA. The display area AA is an area for performing display, and the non-display area NA is an area for setting a circuit structure for driving the display panel to perform display. The display area AA may occupy a large area of the display panel, the display area AA may be disposed at the center of the display panel, for example, a center area, and the non-display area NA is an area outside the display area AA, and may be defined as an edge area of the display panel, for example, a peripheral area.
In the embodiment of the present application, the display panel 100 includes a first substrate 110 and a second substrate 120 disposed opposite to each other, and as shown with reference to fig. 3, the first substrate 110 and the second substrate 120 are generally transparent materials so as to transmit light. The first substrate 110 and the second substrate 120 may be bonded together by a frame sealant, a predetermined space may be provided between the first substrate 110 and the second substrate 120, and the liquid crystal layer 130 may be disposed in the predetermined space.
The liquid crystal material may be dropped between the first substrate 110 and the second substrate 120 through a drip irrigation process, and the first substrate 110 and the second substrate 120 need to be kept parallel as much as possible, so that the cell thickness (cell gap) of the display panel at each region is kept substantially uniform, that is, the thickness of the liquid crystal layer 130 at each region is kept uniform, because the cell thickness is one of the influencing factors influencing the uniform display of the display panel, and the cell thickness is kept uniform, which contributes to the uniform display. In order to achieve uniform display and to achieve a sufficient arrangement space of the liquid crystal layer 130, a spacer (spacer) needs to be provided between the first substrate 110 and the second substrate 120. The spacers may include spherical spacers and columnar spacers (PS).
The column spacers are disposed in the non-pixel region, and are used to support the first substrate 110 and the second substrate 120, preventing the first substrate 110 and the second substrate 120 from contacting, without affecting the display of the display panel. The material of the column spacer may be a photosensitive resin such as an acrylic resin. The columnar spacers may be formed by a photolithographic process. The cross section of the columnar spacer may be inverted trapezoidal.
In the embodiment of the present application, a plurality of scan lines and a plurality of data lines are disposed on a side surface of the first substrate 110, which is close to the second substrate 120, the plurality of scan lines are arranged at a predetermined distance along a direction, and the plurality of data lines are disposed along a direction perpendicular to the scan lines, so that a pixel area of the display panel is defined by the scan lines and the data lines, the pixel area is disposed in an array, and a display electrode 140 is formed on a surface of the pixel area. Thin Film Transistors (TFTs) are formed at intersections of the respective scanning lines and the respective data lines, and apply data signals of the data lines to the respective pixel electrodes by scanning signals applied from the scanning lines. That is, a plurality of display electrodes 140 are disposed at a side of the first substrate 110 adjacent to the second substrate 120, so that display of the liquid crystal display panel is realized using the display electrodes 140.
In the embodiment of the present application, the display panel 100 includes a plurality of display modes, and the liquid crystal deflection angle of the liquid crystal layer 130 may be different between different display modes, and specifically, the plurality of display modes includes a first display mode and a second display mode, where the brightness of the display panel may be the target brightness when the first display mode performs display. As an example, the first display mode may be a normal display mode.
In the embodiment of the present application, a plurality of adjustment electrodes 150 are disposed on a side of the second substrate 120 near the first substrate 110, and switching between different display modes can be achieved by applying different voltages to the adjustment electrodes 150.
Specifically, the first adjustment voltage is applied to the adjustment electrode 150 to obtain the second display mode, and the first display voltage is applied to the display electrode 140 to obtain the target brightness, that is, after the first adjustment voltage is applied to the adjustment electrode 150 to switch the display mode to the second display mode, in order to avoid the problem of the display brightness of the second display mode, the first display voltage may be applied to the display electrode 140 to obtain the target brightness, so that the brightness of the display panel in the second display mode is the same as the brightness of the display panel in the first display mode, and the brightness of the display panel is not changed when the first display mode is adjusted to the second display mode, so that the flicker problem of the display panel during the mode switching is not caused.
That is, by applying different adjustment voltages to the adjustment electrode 150 to realize switching between the plurality of display modes, different display modes can be applied for different application scenarios, and brightness adjustment between different display modes can be realized by using the display electrode 140, for example, brightness between different display modes is kept the same or different, so as to meet various demands of users.
In the embodiment of the present application, after the first adjustment voltage is applied to the adjustment electrode 150 to adjust the display mode to the second display mode, if the second display voltage is applied to the display electrode 140, the second brightness is the brightness of the display panel corresponding to the second display mode, and when the first display mode is performed, the second display voltage is applied to the display electrode 140 to obtain the target brightness, and the second brightness is smaller than the first brightness of the first display mode, that is, the brightness obtained by applying the same display voltage to the display electrode 140 in different display modes is different. If the second display mode is also desired to achieve the target brightness, the voltage of the display electrode 140 may be adjusted, and in particular, the second display voltage may be adjusted to be the first display voltage, where the first display voltage may be the product of the ratio of the target brightness and the second display voltage.
In practical application, when switching between different display modes, each display mode can correspond to a group of display parameters (gamma codes), and the display parameters and the display voltage for realizing the target brightness have a corresponding relation, so that the display voltage for realizing the target brightness in a certain display mode can be directly determined by using the display parameters, and the display voltage corresponding to the target brightness can be rapidly determined when the display mode is switched on the display panel. Specifically, the second display mode may correspond to the first display parameter, a first correspondence exists between the first display parameter and the first display voltage, and then the first display voltage of the second display mode may be determined by using the first display parameter, and the first display voltage is directly applied to the display electrode to achieve the target brightness of the second display mode.
In the embodiment of the application, the plurality of display modes at least comprise peep-proof modes, that is, the plurality of display modes can comprise a plurality of peep-proof modes, the visual angles of the display panels corresponding to different peep-proof modes are different, and therefore the visual angles of the display panels can be changed by switching among the plurality of peep-proof modes, and the requirement of various visual angle changes of users is met.
In practical application, the adjustment of the peep-proof mode is realized by using different liquid crystal deflection angles of the liquid crystal layer 130, the adjustment voltages of the adjustment electrodes 150 corresponding to different peep-proof modes are different, the adjustment voltages are different, the liquid crystal deflection angles are different, the corresponding light transmission amounts of the display panels are different at the moment, the brightness of the display panels is finally different, at the moment, the display voltages of the display electrodes 140 can be adjusted, the display panels have the same brightness as that of the display panels in the normal display mode, and the influence of brightness change on the display effect of the display panels after the display panels are adjusted to the peep-proof mode is avoided.
As an example, the first display mode is a normal display mode, the second display mode is a peep preventing mode, the liquid crystal deflection angle corresponding to the first display mode is θ1, the liquid crystal deflection angle corresponding to the second display mode is θ2, θ1 is not equal to θ2, the target brightness corresponding to the first display mode is Lux1, the second brightness corresponding to the second display mode is Lux2, lux1 is not equal to Lux2, that is, when the first adjustment voltage is applied to the adjustment electrode 150 to turn on the peep preventing mode, the deflection angle of the liquid crystal layer 130 is changed under the influence of the electric field force, the corresponding liquid crystal transmission amounts are different, the brightness is different, but because the positions of the adjustment electrode 150 and the display electrode 140 are determined and the voltage distribution is uniform, the electric field stress is fixed, the brightness of the second display mode can be calculated by using the K value, the brightness of the second display mode is also adjusted to Lux1, specifically, the second display voltage can be multiplied by K, the first display voltage can be obtained, and the subsequent display voltage can be directly obtained in the mode of the peep preventing mode by using the gamma VF 1.
In the embodiment of the application, different liquid crystal deflection angles of different peep preventing modes lead to different viewing angles of the display panel, and the larger the adjustment voltage applied to the adjustment electrode is, the smaller the viewing angle of the display panel is, that is, the adjustment voltage applied to the adjustment electrode is inversely related to the viewing angle of the display panel corresponding to the peep preventing mode.
In the embodiment of the application, the display panel 100 includes a Color Film (CF) layer 160 and a conductive layer, the color film layer 160 is disposed on a side of the second substrate 120 close to the first substrate 110, the conductive layer is disposed on a side of the color film layer 160 away from the second substrate 120, and referring to fig. 4, the conductive layer includes a plurality of adjustment electrodes 150, that is, the plurality of adjustment electrodes 150 are disposed on a side of the color film layer 160 away from the second substrate 120, and then the adjustment electrodes 150 can be used to realize switching between a plurality of display modes.
In practical applications, the color film layer 160 includes a Black Matrix (BM) 161, where the black matrix 161 is used to block light except for the pixel region from exiting, and the black matrix 161 may be formed of a black light-shielding organic material. The color film layer 160 corresponds to the pixel area, and the color film layer 160 is used for controlling the color of the light emitted to realize color display, so that the color film layer 160 includes color film layers with multiple colors, for example, the color film layer 160 may be a red color film layer, a green color film layer or a blue color film layer.
That is, the black matrix 161 is used to divide the color film layer 160, thereby realizing that the color film layer 160 corresponds to each pixel region, each pixel region including any one of a red color film layer, a green color film layer, and a blue color film layer.
