In the related art, the display screen has a relatively single display effect for each display color. For example, the display screen displays red lightly. It can be seen that this relatively single display effect cannot meet the diverse display needs. Summary of the invention

[0049] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0050] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. The described embodiments should not be regarded as limiting the present application. All other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0051] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it can be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0052] In the following description, the terms "first\second" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0054] It should be understood that in the various embodiments of the present application, the size of the serial number of each implementation process does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0055] The present application provides a display device, including a display array composed of a plurality of display units. For two (kinds of) display units (a first display unit and a second display unit) that are adjacent in a first dimension and correspond to the same primary color in the display array, the two display units have different color expressions for the primary color due to the different color resistance components included in each. By using the two display units including different color resistance components, a diversified display of the primary color can be presented, avoiding the problem of poor visual experience caused by too single color display.

[0056] Figure 1 The schematic diagram of the structure of the display device in the embodiment of the present application is shown. Figure 1 .like Figure 1 As shown, the display device includes a display array composed of a plurality of display units. Figure 1 In the example, the display unit and the display array are both rectangular in shape. In actual applications, the shape of the display unit and the shape of the display array composed of multiple display units are determined according to actual conditions. Usually, the display array includes X rows and Y columns of display units, and X and Y are both positive integers greater than or equal to 2. For the convenience of description, Figure 1 This is just a specific example, where the display array is presented with 5 rows and 5 columns of display units, and does not represent all possible situations.

[0057] It is understood that the display screen of electronic devices such as laptops, tablet computers, and mobile phones includes a display array. If the display array included in the display screen of an electronic device is regarded as a complete array, the display array included in the display device in this application can be a complete array or a part of a complete array, and no specific limitation is made to this.

[0058] The plurality of display units in the display array include two types of display units: a first display unit and a second display unit. The two display units in the display array must satisfy the following conditions: the first display unit and the second display unit are adjacent to each other in a first dimension of the display array. For example, the first display unit and the second display unit are in Figure 1 Two display units in the same column or row of the display array shown. The first display unit and the second display unit correspond to a primary color. That is, the first display unit and the second display unit can generate colors corresponding to the same primary color. Therefore, in layman's terms, in the display array, two display units that can generate colors corresponding to the same primary color and are adjacent in the first dimension can be regarded as the first display unit and the second display unit.

[0059] Considering that the primary colors in practical applications include red, green and blue, each display unit in the display array in the present application can generate a color corresponding to one of the primary colors. In some embodiments, it is possible that all display units in the display array generate colors corresponding to the same primary color. It is possible that a part of all display units in the display array generates a color corresponding to one of the three primary colors, and another part generates a color corresponding to one of the other two primary colors of the three primary colors except the one of the three primary colors. It is also possible that a first part of all display units in the display array generates a color corresponding to a first primary color of the three primary colors, a second part generates a color corresponding to the second primary color, and a third part generates a color corresponding to the third primary color.

[0060] In this way, the first display unit and the second display unit can be two display units in the display array that can produce colors corresponding to the primary color red, can be two display units in the display array that can produce colors corresponding to the primary color blue, or can be two display units in the display array that can produce colors corresponding to the primary color green.

[0061] like Figure 2 In the display array shown, which is capable of producing red, green, and blue, only the primary color green has two display units: a first display unit (Green 1) and a second display unit (Green 2). Figure 3 and Figure 4In the display array capable of generating red, green and blue, the three primary colors of red, green and blue each have two display units: Red 1 and Red 2, Green 1 and Green 2, Blue 1 and Blue 2. The first display unit and the second display unit correspond to a sub-pixel of the corresponding primary color, and the corresponding primary color is the same primary color corresponding to the two display units. Figure 2-Figure 4 The description is made by taking the sub-pixel formed by two display units as a circle as an example.

[0062] From the perspective of three primary colors, if the first display unit and the second display unit are two display units that generate colors corresponding to red, the first display unit and the second display unit can be regarded as the first display unit and the second display unit under the red primary color. If the first display unit and the second display unit are two display units that generate colors corresponding to green, the first display unit and the second display unit can be regarded as the first display unit and the second display unit under the green primary color. If the first display unit and the second display unit are two display units that generate colors corresponding to blue, the first display unit and the second display unit can be regarded as the first display unit and the second display unit under the blue primary color.

[0063] In practical applications, the display array may include a first display unit and a second display unit for one of the three primary colors, or may include a first display unit and a second display unit for two or three of the three primary colors, depending on the specific situation. For a primary color that does not have two display units in the display array, it corresponds to a display unit in the display array (used as a display unit for the primary color), and the composition structure and working principle of the display unit are similar to those of the first and second display units, thereby generating the color of the primary color.

[0064] The first display unit at least includes a first color resist corresponding to the primary color that the first display unit can produce. The second display unit at least includes a second color resist corresponding to the primary color that the second display unit can produce. In practical applications, the first color resist and the second color resist may be filters for filtering the colors corresponding to the generated primary colors. Since the first color resist and the second color resist are different, the filtering results for the colors corresponding to the same primary color are also different. Naturally, after filtering with different effects of the first color resist and the second color resist, two display units that can produce colors corresponding to the same primary color have different color expressions for the same primary color in the first display unit and the second display unit. For example, one of the display units shows the color of the primary color as saturated, and the other display unit shows the color of the primary color as faint.

[0065] It can be seen that in the present application, for two display units that are adjacent in the first dimension and correspond to the same primary color, the two display units have different color resistances for the same primary color because the two display units each include different color blocking components. The same primary color is expressed as different display effects, which reflects the diversity of color display and can effectively avoid the problem of poor visual effects caused by too single color display.

[0066] This application is a hardware design. In a display array, two display units corresponding to the same primary color are adjacently designed in the same dimension, and the color resistance components of the two display units are designed to be different, thereby obtaining the effect of different color expressions for the same primary color. It is a novel hardware design that can meet the demand for the same primary color to be displayed in a variety of colors, and improve the usability and applicability of display products such as electronic devices.

[0067] like Figure 5 As shown, for the first display unit and the second display unit in the display array, each display unit includes a controllable control unit, a light emitting element located above the controllable control unit, and a color resist element located above the light emitting element. The controllable control unit is used to control the light emitting element to be in a light emitting state or to control the light emitting element to emit light, and the light emitted by the light emitting element after being acted upon by the color resist element is used as the light emitted by the display unit.

[0068] Regardless of whether it is the first display unit and the second display unit under the red primary color or the green primary color, or the first display unit and the second display unit under the blue primary color, the two display units have different color expressions for the same primary color due to the different color resists included in them. Considering that one of the functions of the color resist is to change the spectrum of the primary color light emitted by the light emitting element, for the color resists of the two display units, the ability of the first color resist to change the spectrum of the primary color light of the first light emitting element included in the first display unit is different from the ability of the second color resist to change the spectrum of the primary color light emitted by the second light emitting element included in the second display unit.

[0069] In the case where both the first color block and the second color block are filters, the filters can filter out light of some bands in the spectrum of the primary color light emitted by the light emitting component, and retain light of the required bands. The first color block and the second color block in the present application have different filtering characteristics, one with strong filtering ability and the other with weak filtering ability. The one with strong filtering ability can filter out all or most of the light of the unnecessary bands in the spectrum of the primary color light emitted by the light emitting component, and retain all or most of the light of the required bands. The color block with weak filtering ability is not as effective as the color block with strong filtering ability in filtering light of the unnecessary bands, resulting in the light retained by the color block with weak filtering ability containing some light of the unnecessary bands. In layman's terms, the light obtained by the filtering effect of the color block with strong filtering ability is purer than the light obtained by the filtering effect of the color block with weak filtering ability, and includes more light of the required bands.

[0070] In the present application, the difference in the ability of the two color resists to change the spectrum of the primary color light generated by the corresponding light emitting element is mainly due to the different target values ​​of the same performance parameter of the color resists. Specifically, the target values ​​of the same performance parameter of the first color resist and the second color resist are different.

[0071] In some embodiments, the same performance parameter may be the thickness of the color component. The thickness values ​​of the two color components may be different. In the first and second color resists, the thicker color resist has a stronger filtering ability, while the thinner color resist has a weaker filtering ability. The light obtained through the filtering effect of the thicker color resist is purer, the color is more saturated, close to the natural light of the base color, and the color gamut is wider or broader. The light obtained through the filtering effect of the thinner color resist will be doped with light of unmixed bands (light of unnecessary bands), the color is lighter, and the color gamut is narrower.

[0072] In some embodiments, the same performance parameter can be used to characterize the material of the color block. Color blocks of different materials have different filtering capabilities. In practical applications, filters may include filters made of glass, metal film, plastic, and other materials. A filter using a metal film can be used as a filter with a strong filtering capability. A filter using a glass material can be used as a filter with a weak filtering capability. The light obtained by filtering a filter with a strong filtering capability is more saturated and has a wider color gamut. The light obtained by filtering a filter with a weak filtering capability is fainter and has a narrower color gamut.

[0073] It can be seen that in this application, on the display unit, different color gamuts (wide color gamut and narrow color gamut) of the same base color are realized by designing the color blocking member with different materials or different thicknesses. In actual use, at least one of the wide color gamut and the narrow color gamut can be selected for color display according to the use requirements, so as to achieve diversified display.

[0074] In the present application, assuming that the same performance parameter is the thickness of the color component, the target value (thickness value) of the thickness of the first color resist component can be greater than the target value (thickness value) of the thickness of the second color resist component. In this way, the driving current used when the first controllable device of the first display unit controls the first light-emitting component to be in a light-emitting state can be greater than the driving current used when the second controllable device of the second display unit controls the second light-emitting component to be in a light-emitting state. This is because: the thicker the color resist component, the darker the brightness of the light passing through the color resist component. Conversely, the thinner the color component, the brighter the brightness of the light passing through the color resist component. In the case where the primary consideration of the display array is display brightness, for a thick color resist component, in order to achieve the same brightness as a thin color resist component, the driving current of the controllable device can be increased to make the primary color light emitted by the first light-emitting component brighter and the brightness of the light filtered by the color resist component brighter, so as to meet the demand that display brightness is the primary consideration.

[0075] It can be seen from the above scheme that in the present application, in terms of hardware, for the first display unit and the second display unit in the display array, by designing different thicknesses of the color resist elements, and providing a larger driving current for the controllable components corresponding to the thick color resist elements and a smaller driving current for the controllable components corresponding to the thin color resist elements, two colors with different color gamuts, one with a narrow color gamut and one with a wide color gamut, are generated for the same primary color corresponding to the two display units.

[0076] It can be understood that if the display array includes the first display unit and the second display unit under the red primary color, the display array can generate a narrow color gamut or a wide color gamut color for red. If the display array includes the first display unit and the second display unit under the green primary color, the display array can generate a narrow color gamut or a wide color gamut color for green. If the display array includes the first display unit and the second display unit under the blue primary color, the display array can generate a narrow color gamut or a wide color gamut color for blue.

[0077] It can be understood that the present application uses the example that the thickness of the first color resist is greater than the thickness of the second color resist. Of course, the thickness of the second color resist may be greater than the thickness of the first color resist. Please refer to the above for understanding and no further explanation is given.

[0078] The first display unit and the second display unit correspond to the same sub-pixel. The sub-pixel shape can be a regular shape such as a circle, a square, a rectangle or other irregular shapes, preferably a regular shape. Figure 2-Figure 4 The sub-pixel is circular. One of the first display unit and the second display unit may correspond to a portion of the sub-pixel, and the other display unit may correspond to another portion of the sub-pixel. For example, Figure 2 The left half of the green sub-pixel corresponds to the first display unit, and the right half corresponds to the second display unit. Figure 3In the red, blue, and green sub-pixels shown, the left half of the sub-pixel corresponds to the first display unit under the corresponding primary color, and the right half corresponds to the second display unit under the corresponding primary color. In the design of the display unit, the second light-emitting element of the second display unit is adjacent to the first light-emitting element of the first display unit. The second color-blocking element of the second display unit is adjacent to the second color-blocking element of the first display unit. In this way, Figure 2 and Figure 3 The left and right halves of the neutron pixel correspond to the display effects of primary colors in different color gamuts.

[0079] In addition to the left and right halves, sub-pixels can also be divided into the middle and surrounding parts. Figure 4 As shown, the middle part and the surrounding part of the sub-pixel correspond to primary colors of different color gamuts. This situation is caused by the following design: the second light-emitting element of the second display unit surrounds the first light-emitting element of the first display unit. The second color resistance element of the second display unit surrounds the second color resistance element of the first display unit. The middle part of the sub-pixel is formed as a high color gamut (or wide color gamut) corresponding to the primary color, and the surrounding part is a low color gamut (or narrow color gamut) corresponding to the primary color. The above is an explanation based on a circle as an example. In addition, the sub-pixel can also be square or U-shaped, and it can also be designed with a high color gamut in the middle part and a low color gamut in the surrounding part.

[0080] In the display array, considering the consistency of the design, the size or size of the color resist of the first display unit corresponding to the same primary color can be the same. The size or size of the color resist of the second display unit corresponding to the same primary color can be the same. The thickness of the color resist of the first display unit corresponding to the same primary color can be the same. The thickness of the color resist of the second display unit corresponding to the same primary color can be the same. In this way, it is convenient to realize two different color gamuts of wide and narrow for the same primary color through such consistency and feasibility design of the hardware.

[0081] In the display array, for the color resist members of two display units with different primary colors, the sizes or sizes of the color resist members of the first display unit corresponding to the different primary colors may be the same or different. The sizes or sizes of the color resist members of the second display unit corresponding to the different primary colors may be the same or different. In the first display unit corresponding to the different primary colors, the sizes or sizes of the color resist members of the first display unit corresponding to some of the primary colors may be different, or the sizes or sizes of the color resist members of the first display unit corresponding to all of the primary colors may be different. In the second display unit corresponding to the different primary colors, the sizes or sizes of the color resist members of the second display unit corresponding to some of the primary colors may be different, or the sizes or sizes of the color resist members of the second display unit corresponding to all of the primary colors may be different, depending on the specific circumstances.

[0082] Of course, considering the consistency of the design, the size or size of the color components of the first display unit corresponding to different primary colors can be the same. The size or size of the color resistance components of the second display unit corresponding to different primary colors can be the same. By utilizing this consistent design, different color gamuts of each primary color can be effectively achieved.

[0083] In the display array, for the color resist members of two display units of different primary colors, the thickness of the color resist members of the first display unit corresponding to the different primary colors can be the same or different. The thickness of the color resist members of the second display unit corresponding to the different primary colors can be the same or different. Considering the consistency of the design, it is preferred that the thickness of the color resist members of the first display unit corresponding to the different primary colors is the same. The thickness of the color resist members of the second display unit corresponding to the different primary colors is the same. By utilizing this consistent design, different color gamuts of each primary color can be effectively achieved.

[0084] In the present application, for the first display unit and the second display unit of the same primary color, it is possible that a plurality of first display units are located in the same column of the display array. A plurality of second display units are located in the same column of the display array. A plurality of first display units are located in the same column of the display array and a plurality of second display units are located in the same column of the display array and are arranged alternately. That is, the first display unit and the second display unit of the same primary color are arranged crosswise or staggered in the column dimension to achieve the adjacency of the two display units in the column dimension.

[0085] In the present application, for the first display unit and the second display unit of the same primary color, multiple first display units can be located in the same row of the display array. Multiple second display units are located in the same row of the display array. Multiple first display units are located in the same row of the display array and multiple second display units are located in the same row of the display array. In other words, the first display unit and the second display unit of the same primary color are crossed or staggered in the row dimension to achieve the adjacent two display units in the row dimension. Figure 2-Figure 4 In the example, the first and second display units (eg, Green 1 and Green 2) can be considered to be adjacent in the row dimension.

[0086] In the present application, for a first display unit and a second display unit that are adjacent to each other in the first dimension for the same primary color, when the thickness value of the first color resist member of the first display unit is greater than the thickness value of the second color resist member of the second display unit, or the filtering characteristics or capabilities of the material used for the first color component of the first display unit are stronger than the filtering characteristics or capabilities of the material used for the second color component of the second display unit, it can be considered that a wide color gamut of the primary color can be achieved using such a first display unit, and a narrow color gamut of the primary color can be achieved using such a second display unit, thereby achieving two different color gamuts of the same primary color.

[0087] If a first display unit is designed to form a central area of ​​a regular shape such as a square, a circle or a U-shaped shape, and a second display unit is designed to form a peripheral or surrounding area of ​​the regular shape, and the peripheral area surrounds the central area, then the first display unit and the second display unit can form a primary color of the regular shape. Figure 4 The middle area shown is the primary colors of the high color gamut and the surrounding areas are the primary colors of the low color gamut. The two different color gamuts of each primary color can be used to realize the color display of each primary color under different color gamuts.

[0088] It can be understood that if the plurality of first display units are designed to form a central area of ​​a regular shape, and the plurality of second display units are designed to form a peripheral area of ​​the regular shape, the plurality of first display units and the plurality of second display units can form a primary color group of the regular shape. Such a primary color group can realize enhanced display of primary colors in two different color gamuts, thereby meeting the requirements of different display effects.

[0089] In the present application, the wide color gamut display of the primary color achieved by the first display unit makes the color or hue of the primary color more saturated and closer to the natural light of the primary color. The narrow color gamut display of the primary color achieved by the second display unit makes the color or hue of the primary color lighter in terms of display effect.

[0090] The following is combined with Figure 2-Figure 6 The technical solution of this application is further explained.

[0091] like Figure 2-Figure 4 In the display array, the color blocking element of the display unit may be a filter. The light emitting element of the display unit may be a light emitting material such as a light emitting diode. The controllable element of the display unit may be a TFT (Thin film Transistor). Figure 2-Figure 4 The explanation is based on two groups of three primary colors of red, blue and green. It can be understood that it is only a specific example and does not represent all situations. Substrate is a substrate on which a controllable control array, such as a TFT array, is arranged. That is, the TFT of each display unit in the display array constitutes a TFT array. The TFT array is arranged on the substrate. The TFT array is G1, G2...Gn rows and S1, S2...Sm columns.

[0092] exist Figure 2 In the example, from the perspective of primary colors, for the primary color green, the display array includes two display units under the primary color green: the first display unit and the second display unit. For primary colors such as blue and red, the display array only has one display unit under the primary color. Figure 2As shown in the figure, because there are two display units for the green primary color, the display device has two color expressions for the green primary color: high color gamut color expression and low color gamut color expression. For the two primary colors of red and blue, because there is only one display unit, Figure 2 The display device shown below has only one color representation for either of the two primary colors.

[0093] exist Figure 2 In the figure, taking a group of red, green and blue as an example, a display unit under the red primary color may include a filter 1, a light-emitting material 1 and a TFT 1. A first display unit under the green primary color includes a filter 2, a light-emitting material 2 and a TFT 2. A second display unit under the green primary color (a display unit adjacent to the first display unit under the green primary color in the row dimension) includes a filter 3, a light-emitting material 3 and a TFT 3. The display unit under the blue primary color includes a filter 4, a light-emitting material 4 and a TFT 4. Among them, the light-emitting material 1 is used to emit red light. The light-emitting material 2 and the light-emitting material 3 are used to emit green light. The light-emitting material 4 is used to emit blue light. The thickness of the filter 2 included in the first display unit under the green primary color is thicker than the thickness of the filter 3 included in the second display unit. For the relevant situations of the display units under other groups of red, green and blue, please refer to the understanding and will not be repeated.

[0094] Understandably, Figure 2 In the figure, it is illustrated that the two primary colors of red and blue have only a single color gamut, while the primary color of green has two color gamuts: a high color gamut and a low color gamut.

[0095] If the application layer wants the display device to achieve green high color gamut display, the application layer sends an instruction to the hardware layer for indicating that green is displayed in high color gamut mode, and the driving device of the hardware layer receives the display instruction, responds to the display instruction, and generates a driving signal. The driving signal can control the TFT to turn on the row. For example, the TFTs of some or all rows such as G1, G2, and G3 are controlled to turn on to achieve the whole row of the TFT array. In addition, the driving signal can be input to some columns of TFT to input current to some columns such as S1, S2, S4, S5, S6, and S8, and the current is used as the driving current of the TFT of the display unit enabled under each primary color. The display unit with current input to the TFT is an enabled display unit. The second display unit under the green primary color is a display unit for realizing a low color gamut. In this scenario, the second display unit may not be enabled, such as the S columns where TFT 3 and TFT 7 are located, such as S3 and S7, may not input the driving current, and TFT 3 and TFT 7 are in the closed state.

[0096] When a driving current is input, TFT 1, TFT 2, TFT 4, TFT 5, TFT 6, and TFT 8 control the luminescent material belonging to the same display unit as each TFT to be in a luminescent state. The light emitted by each luminescent material is filtered by the filter belonging to the same display unit as each luminescent material, so that each display unit generates light corresponding to its own primary color. Among them, for the primary color green, the thickness of filter 2 is thicker than that of filter 3. After the filtering effect of filter 2, a more saturated green color can be obtained, thereby realizing a wide color gamut display of green.

[0097] If the application layer wants the display device to achieve green low color gamut display, the application layer sends an instruction to the hardware layer to indicate that green is displayed in low color gamut mode, and the driving device of the hardware layer receives the display instruction, responds to the display instruction, and generates a driving signal. The driving signal can control the TFT to turn on the row. For example, the TFTs of some or all rows such as G1, G2, and G3 are controlled to turn on to achieve the whole row of the TFT array. In addition, the driving signal can be input to some columns of TFT, such as inputting current to some columns such as S1, S3, S4, S5, S7, and S8, and the current is used as the driving current of the TFT of the display unit enabled under each primary color. The first display unit under the green primary color is a display unit for realizing a high color gamut. In this scenario, the first display unit may not be enabled, such as the S columns such as S2 and S6 where TFT 2 and TFT 6 are located may not input the driving current, and TFT 2 and TFT 6 are in the off state.

[0098] When a driving current is input, TFT 1, TFT 3, TFT 4, TFT 5, TFT 7, and TFT 8 control the luminescent material belonging to the same display unit as each TFT to be in a luminescent state. The light emitted by each luminescent material is filtered by the filter belonging to the same display unit as each luminescent material, so that each display unit generates light corresponding to its own primary color. Among them, for the primary color green, the thickness of filter 3 is thinner than that of filter 2. After the filtering effect of filter 3, a light green color can be obtained, thereby realizing a low color gamut display of green.

[0099] It can be seen that in the above scheme, in terms of hardware, by designing two display units (the first display unit and the second display unit) for the green primary color and designing the filters of the two display units to have different thicknesses, two different color gamuts of the green primary color are displayed, thereby realizing two different color expressions of the green primary color.

[0100] In simple terms, Figure 2The schematic diagram shown is a schematic diagram of a display device that can realize a high and low color gamut of a single primary color. It can be understood that by reasonable inference from this figure, a schematic diagram of a display device that can realize a high and low color gamut of two primary colors or a high and low color gamut of three primary colors can be inferred. Figure 3 and Figure 4 It is a schematic diagram of the high and low color gamuts of the three primary colors achieved by a display device.

[0101] like Figure 3 As shown, from the perspective of primary colors, for each of the three primary colors of red, green and blue, the display array includes two display units: a first display unit and a second display unit. The display device has two color expressions for each primary color: a high color gamut color expression and a low color gamut color expression.

[0102] exist Figure 3 In the example, taking a group of red, green and blue as an example, a first display unit under the red primary color may include a filter 1, a light-emitting material 1 and a TFT 1. A second display unit under the red primary color may include a filter 2, a light-emitting material 2 and a TFT 2. A first display unit under the green primary color includes a filter 3, a light-emitting material 3 and a TFT 3. A second display unit under the green primary color includes a filter 4, a light-emitting material 4 and a TFT 4. A first display unit under the blue primary color includes a filter 5, a light-emitting material 5 and a TFT 5. A second display unit under the blue primary color includes a filter 6, a light-emitting material 6 and a TFT 6. Among them, the thickness of the filter included in the first display unit under each primary color is thicker than the thickness of the filter included in the second display unit under each primary color. For the relevant situations of the display units under other groups of red, green and blue, please refer to the understanding and will not be repeated.

[0103] If the application layer wants the display device to achieve high color gamut display of three primary colors, the application layer sends an instruction to the hardware layer to instruct the red, green and blue colors to be displayed in high color gamut mode. The driver of the hardware layer receives the display instruction, responds to the display instruction, and generates a drive signal. The drive signal can control the TFT to turn on the row. For example, the TFTs of some or all rows of G1, G2, G3 are controlled to turn on to turn on the entire row of the TFT array. In addition, the drive signal can be input to some columns of TFT to input current to some columns such as S1, S3, S5, S7, S9, and S11, and the current is used as the drive current for the TFT of the display unit enabled under each primary color. The second display unit under the three primary colors is a display unit for realizing a low color gamut. In this scenario, the second display unit under each primary color may not be enabled. For example, the S columns where TFT 2, TFT4, TFT 6, TFT 8, TFT 10, and TFT 12 are located, such as S2, S4, S6, S8, S10, and S12, may not be input with a driving current, and TFT 2, TFT4, TFT6, TFT 8, TFT 10, and TFT 12 are in an off state.

[0104] When a driving current is input, TFT 1, TFT 3, TFT 5, TFT 7, TFT 9, and TFT 11 control the luminescent material belonging to the same display unit as each TFT to be in a luminescent state. The light emitted by each luminescent material is filtered by the filter belonging to the same display unit as each luminescent material, so that each display unit generates light corresponding to its own primary color. For each primary color, a more saturated primary color can be obtained through the filtering effect of the thick filter, thereby realizing a wide color gamut display of each primary color.

[0105] If the application layer wants to display a low-color gamut display of the three primary colors by the device, the application layer sends an instruction to the hardware layer to indicate that all three primary colors, namely red, green, and blue, are to be displayed in the low-color gamut mode. The driving device in the hardware layer receives this display instruction and generates a driving signal. This driving signal can control the TFT to turn on rows. For example, it controls the TFTs of some or all rows such as G1, G2, G3 to turn on, so as to achieve the full-row turn-on of the TFT array. In addition, this driving signal can be input to some columns of the TFT to input current to some columns such as S2, S4, S6, S8, S10, S12, and this current serves as the driving current for the TFTs of the display units enabled under each primary color. The first display units under the three primary colors are the display units for achieving a high-color gamut. In this scenario, the first display units under each primary color may not be enabled. For example, the S columns where TFT 1, TFT3, TFT 5, TFT 7, TFT 9, TFT 11 are located, such as S1, S3, S5, S7, S9, S11, may not receive the input of the driving current, and TFT 1, TFT3, TFT 5, TFT 7, TFT 9, TFT11 are in the off state.

[0106] When there is a driving current input to TFT 2, TFT4, TFT 6, TFT 8, TFT 10, TFT 12, it controls the light-emitting materials belonging to the same display unit as each TFT to be in the light-emitting state. The light emitted by each light-emitting material is filtered by the color filter belonging to the same display unit as each light-emitting material, so that each display unit generates light corresponding to its respective primary color. Among them, for each primary color, through the filtering effect of the thin color filter, a pale primary color can be obtained, thus achieving a narrow-color gamut display for each primary color.

[0107] According to Figure 4 the display device shown, it is also possible to achieve high and low color gamuts for the three primary colors. Different from Figure 3 the primary colors of the first display unit and the second display unit shown, which form a sub-pixel point in a left-and-right half way, Figure 4 the primary colors of the first display unit and the second display unit are those formed by the central region and the peripheral region to form a sub-pixel point. Figure 4 The sub-pixel points in Figure 6 are in a circular ring shape, with the central region being the high-color gamut area and the peripheral region being the low-color gamut area. In addition, the primary colors of the first display unit and the second display unit formed by the central region and the peripheral region to form a sub-pixel point can also be as Figure 4 shown, in a square-within-a-square shape, with the central region being the high-color gamut area and the peripheral region being the low-color gamut area. From Figure 4 the circular ring shape shown and Figure 6 the cross-section of the square-within-a-square shape shown - looking at the same primary color 1, the same primary color 2, the same primary color 1, the color expressiveness of the primary color is that the central region of the cross-section is the high-color gamut area, and both sides (peripheral regions) of the cross-section are the low-color gamut areas. From Figure 2 and Figure 3 From the cross-section of the circle shown - the same primary color 1 and the same primary color 2, the color expression of the primary colors is that the left half is a high color gamut area, and the right half is a low color gamut area.

[0108] The above scheme is explained by taking the display of the three primary colors of red, green and blue in high color gamut or low color gamut as an example. In addition, in some application scenarios, at the same time, some of the three primary colors can be displayed in low color gamut and some of the primary colors can be displayed in high color gamut. For each primary color, when low color gamut is used for display, the TFT included in the display unit capable of displaying low color gamut in the two display units has a driving current, is in the on state, and the display unit is enabled. The TFT included in the display unit capable of displaying high color gamut does not have a driving current, is in the off state, and the display unit is not enabled. For each primary color, when high color gamut is used for display, the TFT included in the display unit capable of displaying high color gamut in the two display units has a driving current, is in the on state. The TFT included in the display unit capable of displaying low color gamut does not have a driving current, is in the off state. Please refer to the understanding of the specific process and will not be repeated.

[0109] It can be seen that in the above scheme, two display units (first display unit and second display unit) are designed for the three primary colors in hardware, and the filters of the two display units under each primary color are designed to have different thicknesses, so as to realize the display of two different color gamuts for each primary color, and realize two different color expressions for each primary color in the three primary colors. In the above scheme, the explanation is given by taking the case that at the same time, for the primary colors with two display units, only one of the two color gamuts is used for display. In some application scenarios, at the same time, for the primary colors with two display units, two color gamuts can be used for display at the same time, which is different from the above scheme of using only one of the color gamuts for display in that: for the primary colors with two color gamuts, the S columns where the TFTs included in the two display units are located are input with current, and the current intensity input to the S column where the TFTs of the first display unit are located is greater than the S column where the TFTs of the second display unit are located, so that the sub-pixels display the high and low color gamuts of the primary colors in the form of the left and right halves at the same time, or display the high and low color gamuts of the primary colors in the form of the central area and the peripheral area at the same time.

[0110] The display device in the present application may be an OLED (Organic Light-Emitting Diode) screen. For the same primary color, when the high color gamut mode is adopted, the primary color can be displayed as a more saturated color, but the driving current of the light-emitting diode is large. When the low color gamut mode is adopted, the primary color can be displayed as a light color, but the driving current of the light-emitting diode is small. It can be understood that a large driving current consumes a large amount of power, and a small driving current consumes a small amount of power. In this way, the power consumption of the high color gamut mode is greater than that of the low color gamut mode. In practical applications, according to actual needs, such as heavy color display effect and light power consumption, or light color display effect and heavy power consumption, one of the high color gamut and low color gamut modes can be selected to display the primary color. The technical solution of the present application balances the color expression and power consumption, and can be flexibly selected from the high color gamut and low color gamut modes of the same primary color according to different application scenarios and actual needs, so as to avoid the problem of a single display effect caused by the screen being able to display only light colors or saturated colors of the primary color.

[0111] The above scheme takes the scheme of realizing two color gamut ranges of wide color gamut and narrow color gamut of the same primary color as an example. The present application can also realize the selection of three or more color gamut ranges under the same primary color by designing three or more different display units under the same primary color, each display unit including the design of its own controllable component, light-emitting component, and color resistance component, as well as the design of color resistance components with different materials or different thicknesses. For example, the selection of three color gamut ranges such as wide color gamut, intermediate color gamut, and narrow color gamut. In this way, in the display array, three or more display units designed for the same primary color can be used, and the thickness of the filter included in each display unit is different. For example, the thickness of the filter is thick, the second thickest, and the thinnest. For the specific design and its working principle, refer to the Figure 1 to Figure 6 The two color gamut ranges are shown for understanding, and the similarities are not repeated here.
