Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the display device according to the present invention with reference to the accompanying drawings and preferred embodiments shows the specific embodiments, structures, features and effects thereof.
In one aspect, as shown in fig. 1 to 9, an embodiment of the present invention provides a display device, including: the display device comprises a processing circuit and a display panel 2, wherein the processing circuit is connected with the display panel 2 and used for sending a preset voltage signal to the display panel 2, the display panel 2 comprises a pixel layer 11, a large number of pixel units 11 are arranged on the pixel layer 11 in an array mode, each pixel unit 11 comprises at least three sub-pixels, the sub-pixels in each pixel unit 11 are arranged in a disordered mode, and the display panel 2 controls the loading voltage of a corresponding area of each sub-pixel according to the preset voltage signal. In the prior art, there is no specific connection between the host and the display in the display device, and one host can use multiple displays, and at this time, when the host is stolen by someone, the content stored in the host can be viewed only by connecting the display screen, so in the prior art, the confidentiality of the display device is poor. In this embodiment, the preset voltage signal generated by the processing circuit is matched with the display panel 2, and when the signal received by the display panel 2 is not the preset voltage signal, the display panel 2 cannot normally display the picture, so that the information in the host can be protected, and the security effect of the display device is improved. Specifically, the sub-pixels in each pixel unit 11 in the display panel 2 are arranged in a random manner, so in this embodiment, the arrangement order of the sub-pixels in the pixel layer of each display panel 2 has uncertainty, the arrangement order of the sub-pixels of each display panel 2 is different, and therefore, the preset voltage signal is related to the arrangement order of the sub-pixels, when the arrangement order of the sub-pixels is changed, the preset voltage signal sent by the processing circuit is also changed, and for the same display screen, the preset voltage signal sent by the processing circuit is the same, so after the display panel 2 is replaced, the arrangement order of the sub-pixels in the display panel 2 after being updated is different from the arrangement order before being updated, and therefore, the display panel 2 after being replaced cannot correctly display the display screen, and therefore, in this embodiment, one display panel 2 corresponds to one processing circuit, so that the display device has a secret effect. The processing circuit needs to provide a voltage signal once each time the display device converts a picture, and the voltage signal sent by the processing circuit to the display panel 2 each time can be referred to as a preset voltage signal. The display panel 2 controls the brightness of the light emitted by each sub-pixel by controlling the loading voltage of the sub-pixel, for example, in an OLED display panel, the loading voltages corresponding to the sub-pixels are different, the colors of the light emitted by the sub-pixels are different, usually, the three colors of red, green and blue constitute a unit, the color displayed by each unit is adjusted by adjusting the brightness of each color, the brightness of the sub-pixel of any color in the unit changes, and the color displayed by the unit is incorrect. Of course, the display panel 2 may also be an LCD screen.
The object of the present invention and the technical problems solved thereby can be further achieved by the following technical measures.
Specifically, as shown in fig. 2, each pixel unit 11 includes a red pixel 111, a green pixel 112, and a blue pixel 113, and the red pixel 111, the green pixel 112, and the blue pixel 113 in each pixel unit 11 are arranged in a random manner, where the red pixel 111, the green pixel 112, and the blue pixel 113 are all sub-pixels. In the prior art, the red, green and blue sub-pixels in each pixel unit 11 are regularly arranged, as shown in fig. 2, one pixel unit 11 includes three sub-pixels, wherein one each of the red pixel 111, the green pixel 112 and the blue pixel 113, and the pixel units 11 in the same column, wherein the red pixel 111 is arranged in the same column, the green pixel 112 is arranged in the same column, the blue pixel 113 is arranged in the same column, and the sub-pixels in the pixel units 11 are arranged in the same arrangement order. In the embodiment, as shown in fig. 1, the arrangement sequence of the red, green, and blue sub-pixels in each pixel unit 11 is disordered, the arrangement sequences of the sub-pixels in different display panels 2 are different, and when the arrangement sequence of the sub-pixels is changed, the preset voltage signal sent by the processing circuit is also changed. For example, in the prior art, if the display panel 2 is to display red, the preset voltage signal generated by the processing circuit at this time needs to control the red pixel 111 in the first column to emit light, and the green pixel 112 and the blue pixel 113 in each pixel unit 11 do not emit light, so that the display panel 2 will display a red image. However, in the display panel 2 provided in this embodiment, the preset voltage signal of the display panel 2 needs to control the first and eighth light-emitting devices in the first row, and the second to seventh light-emitting devices do not emit light, that is, the region corresponding to the red pixel 111 is controlled to emit light, so that the display panel 2 can be ensured to display the red image. If the processing circuit is not changed, that is, the host is not changed, the display in the prior art is connected to the host, or the display panel 2 with different arrangement order of the sub-pixels as shown in fig. 1 is not able to normally display the picture, therefore, the host and the display panel 2 in the embodiment are matched with each other, and neither the display panel 2 nor the host can display the correct picture, if the processing circuit in the embodiment is used to send the preset voltage signal to the display panel 2 as shown in fig. 2, at this time, the display panel 2 cannot display the correct picture, so that the display device has the security effect. In this embodiment, the display panel 2 may be an OLED display screen or an LCD display screen.
Specifically, as shown in fig. 4, the pixel unit 11 includes a red pixel 121, a green pixel 122, a blue pixel 123, and a white pixel 124, and the red pixel 121, the green pixel 122, the blue pixel 123, and the white pixel 124 in each pixel unit 11 are arranged in a disordered manner, wherein the red pixel 121, the green pixel 122, the blue pixel 123, and the white pixel 124 serve as the sub-pixels. In the prior art, the sub-pixels in the display panel 2 may further include: the red pixel 121, the green pixel 122, the blue pixel 123 and the white pixel 124 are sub-pixels of four colors, and each independent sub-pixel corresponds to a circuit which is driven independently. The applied voltage to a subpixel determines the brightness of the subpixel. In this embodiment, each pixel unit 11 includes four colors of pixels, so the arrangement of the sub-pixels is more, and the sub-pixels are more difficult to break. The display panel 2 of the present embodiment has the same principle as the privacy of the processing circuit, and will not be described herein. Fig. 3 is a schematic diagram of an array of four color pixels in the prior art, which is the same as the arrangement method of the three color pixel arrays described in the above embodiments.
Specifically, as shown in fig. 5, the display panel 2 includes a first polarizer 13, a color filter substrate 14, a liquid crystal layer 15, an array substrate 16, a second polarizer 17, and a backlight 18, which are sequentially stacked, the pixel layer 11 is disposed on the color filter substrate 14, the pixel layer 11 is divided into a plurality of pixel regions, regions corresponding to the first polarizer 13 and the second polarizer 17 and the same pixel region are a first region and a second region, respectively, the first region and the second region make the sum of phase differences generated by light be a compensation phase difference, where the compensation phase differences corresponding to at least two pixel regions are different. Light emitted by the backlight source 18 enters the array substrate 16 through the deflection of the second polarizer 17, the processing circuit controls liquid crystal particles in the liquid crystal layer 15 to deflect, so that the light of the backlight source 18 generates a phase difference, the light is deflected for the second time, the light generates the phase difference again, and then the light passes through the first polarizer 13 and is deflected for the third time to generate the phase difference. In the prior art, the first polarizer 13 has the same phase difference everywhere, and the second polarizer 17 has the same phase difference everywhere, so that the sum of the phase differences of the first polarizer 13 and the second polarizer 17 is fixed, in the present embodiment, the sum of the phase differences of the first polarizer 13 and the second polarizer 17 is improved, that is, the compensation phase difference is improved. The pixel layer 11 is divided into a plurality of pixel regions, each of which may correspond to one or more pixels, or one to a plurality of pixel units 11. For example, the compensation phase difference corresponding to at least two pixel regions may be different in a plurality of cases. In the first case, the pixel layer 11 is divided into nine pixel regions, wherein the compensation phase difference corresponding to one pixel region is different from the compensation phase difference corresponding to the other pixel regions, and the compensation phase differences of the other regions are the same. In the second case, the nine regions may be divided into a plurality of groups, one group having the same compensation phase difference, at least three groups, wherein it is preferable that the pixel regions having the same compensation phase difference are not adjacent. Or, the compensation phase difference corresponding to each pixel region is different. The division of the pixel region may be performed in a rectangular shape or in an irregular shape, and is not limited herein. Another way of dividing the regions with better security effect is introduced, where a large number of sub-pixels are arranged in an array on the pixel layer 11, the first, fourth, and eighth … … of each row are analogized in turn as a pixel region, the second and fifth … … of each row are analogized in turn as a pixel region, and the rest of the sub-pixels are used as a pixel region, at this time, the pixel layer 11 is divided into three pixel regions, and the compensation phase differences of other regions corresponding to at least one pixel region and the compensation phase differences of other regions are different, so that the compensation phase differences corresponding to the three pixel regions are all different.
Specifically, as shown in fig. 6, the first polarizer 13 is divided into a plurality of polarization regions 131, and at least two polarization regions 131 make the phase difference of the light different. In order to make the compensation phase differences corresponding to the pixel regions different, the structure of the first polarizer 13 may be improved, specifically, the first polarizer 13 is divided into regions, the first polarizer 13 is divided into a plurality of polarization regions 131, and the division method of the polarization regions 131 may be different from the division method of the pixel regions, that is, the polarization regions 131 correspond to the pixel regions, which is not described herein, at this time, the phase differences at the positions of the second polarizer 17 may be the same, and thus, the compensation phase differences corresponding to the pixel regions are determined by the first polarizer 13 through the polarization regions 131 of the first polarizer 13, so that the phase differences generated by the light beams are determined by the first polarizer 13.
Specifically, as shown in fig. 7, the second polarizer 17 is divided into a plurality of polarization regions 171, wherein at least two polarization regions 171 make the phase difference of the light different. By improving the structure of the second polarizer 17, the compensation phase difference corresponding to the pixel region may also be controlled, specifically, the second polarizer 17 is divided into a plurality of polarization regions 171, the dividing method of the polarization regions 171 is the same as the dividing method of the pixel region, each polarization region 171 may correspond to one or more sub-pixels, or each polarization region 171 corresponds to one or more pixel units 11, at this time, the phase difference at each position of the first polarizer 13 may be the same. In addition, the structures of the first polarizer 13 and the second polarizer 17 may be improved at the same time, specifically, the polarization regions 131 and the polarization regions 171 may be arranged correspondingly, the corresponding polarization regions 131 and the corresponding polarization regions 171 form a group, and the sum of the phase differences in each group is the compensation phase difference, and at this time, it needs to be ensured that the compensation phase differences in at least two groups are different.
Specifically, the polarization region 171 corresponds to at least one sub-pixel, and the shapes of at least two polarization regions 171 are different; the polarization regions 131 correspond to at least one sub-pixel, and at least two of the polarization regions 131 have different shapes. The polarization areas 131 and 171 both correspond to sub-pixels, and therefore, the boundaries of the polarization areas 131 and 171 are arranged along the boundaries of the sub-pixels, ensuring that one sub-pixel corresponds to one compensation phase difference. At least two polarization regions 131 are different in shape, and the shape of each polarization region 131 may be irregular, and the shape of each polarization region 171 may also be irregular, so that the display device is better and difficult to break. Of course, in order to increase the security effect, one polarization region 171 may correspond to one sub-pixel, and in this case, the number of sub-pixels is the same as that of the polarization region 171, and the same applies to the polarization region 131.
Specifically, the boundaries of the polarization regions 171 are staggered from the boundaries of the polarization regions 131. The polarization region 171 is not disposed corresponding to the polarization region 131, and further, more sets of compensation phase differences can be formed on the display panel 2, so that the security effect of the display device is better. Specifically, the regions on the first polarizer 13 corresponding to the sub-pixels in the first and second columns on the pixel layer 11 are referred to as first polarization regions 131, the regions on the first polarizer 13 corresponding to the sub-pixels in the third and fourth columns are referred to as second polarization regions 131, then, each two columns are referred to as one polarization region 131, and so on, and the third polarization region 131 and the fourth polarization region 131 … … are formed in this order. Taking the area on the second polarizer 17 corresponding to the sub-pixels in the first row as the first polarization area 171, the area on the second polarizer 17 corresponding to the sub-pixels in the second row and the third row as the second polarization area 171, then, the area on the first polarizer 13 corresponding to the sub-pixels in every two adjacent rows as the third polarization area 171 and the fourth polarization area 171 … …, when the first polarizer 13 and the second polarizer 17 are attached, the boundary of the first polarization area 171 is placed in the first polarization area 131, at this time, each polarization area 171 and the polarization area 131 are just staggered by one row, for example, 100 rows of sub-pixels are arranged on the pixel layer 11, 50 polarization areas 131 are correspondingly formed on the first polarizer 13, 50 different phase differences are formed on the corresponding first polarizer 13, 51 polarization areas 171 are formed on the second polarizer 17, 51 phase differences are formed on the first polarizer 13, after the display panel 2 is manufactured, 100 compensation phase differences are formed in a conformal mode, so that a plurality of groups of compensation phase differences are arranged on the display panel 2, the display device is difficult to crack, and the confidentiality effect is better.
Besides, in one display panel 2, when the first polarizer 13 and the second polarizer 17 are modified, the arrangement sequence of sub-pixels in the pixel layer 11 can be disordered, so that the security effect of the display device is better.
Specifically, when the display device displays a predetermined image, the phase difference required for the light emitted from the backlight 18 to form a predetermined color is a deflection phase difference, and the voltage is applied to make the phase difference generated by the light be a predetermined phase difference, which is equal to the difference between the deflection phase difference and the compensation phase difference. The liquid crystal particles in the liquid crystal layer 15 have a deflection angle depending on the applied voltage, and different deflection angles of the liquid crystal particles cause different phase differences of light. In the conventional LCD display panel 2, the compensation phase difference corresponding to each sub-pixel is constant, the light emitted by the backlight 18 is an original light source, when the display device displays a preset picture, the phase difference generated by the light emitted by the original light source is a deflection phase difference, the compensation phase difference of the finished display panel 2 is determined, the processing circuit controls the phase difference generated by the liquid crystal particles by using the loading voltage corresponding to each sub-pixel, when the display device displays the preset picture, the phase difference generated by the light by the liquid crystal particles is a preset phase difference, the preset phase difference is equal to the difference between the deflection phase difference and the compensation phase difference, and the loading voltage required by the liquid crystal layer corresponding to the sub-pixel can be obtained after the preset phase difference is known. The following takes fig. 6 to 9 as an example, and specifically describes the phase difference generated by the light rays by each structure with four sub-pixels on the pixel layer 11. As shown in fig. 6, fig. 6 shows the phase difference of the light generated by each polarization region 131 of the first polarizer 13, the phase difference of a, b, c, d generated by the first polarizer 13, respectively, fig. 7 shows the phase difference of e, f, g, h generated by each polarization region 171 of the second polarizer 17, the polarization regions 131 are disposed corresponding to the polarization regions 171, the compensation phase difference of the four pixel regions corresponding to the first polarizer 13 on the pixel layer 11 is a + e, b + f, c + g, and d + h, the deflection phase difference required by the backlight 18 passing through the four sub-pixels is i, j, k, l, respectively, when the display panel 2 displays a predetermined picture, the phase difference generated by the light generated by the corresponding liquid crystal layer pressurized by the applied voltage is i-a-e, respectively, j-b-f, k-c-g and l-d-h, further obtaining the deflection angle required by the liquid crystal layer, further calculating to obtain the loading voltage of each sub-pixel, and further obtaining a preset voltage signal.
Specifically, the main board and the host, the processing circuit is disposed on the main board, and the host is electrically connected to the display panel 2. The processing circuit is arranged on the mainboard of the host computer, so that the content in the host computer can not be displayed when the host computer is separated from the specific display panel 2, and the display device has the technical effect of confidentiality.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
