[0024] Embodiments of the display device, electronic device, and display control method will be described below with reference to the drawings. The following description will focus on the main components of the display device and electronic device, but there may be components and functions not shown or described. The following description does not exclude any components or functions not shown or described.

[0025] (First Embodiment) Figure 1 shows an example of the configuration of the display system 1 in the first embodiment of this technology. This display system 1 is a display system capable of independently displaying images of the central field of view and images of the peripheral field of view, and comprises an imaging device 10, an eye imaging device 15, a display device 20, and a display control device 30.

[0026] The imaging device 10 is, for example, a camera and is capable of supplying digital image data captured in video to the display control device 30. The eye imaging device 15 is, for example, a camera for photographing the eye and is capable of supplying digital image data captured in video of the user's eye on the display device 20 to the display control device 30.

[0027] Figure 2 illustrates the display range of the first image 20H, which has a first resolution, and the display range of the second image 20L, which has a second resolution lower than the first image 20H. For example, the first image 20H corresponds to the central field of view, and the second image 20L corresponds to the peripheral field of view. The display device 20 is a device that uses a video signal based on digital image data to illuminate light-emitting elements row by row, and can display the first image 20H and the second image 20L. The display device 20 has, for example, a current-driven light-emitting element. As this light-emitting element, an organic electroluminescent element, an LED element, a semiconductor laser element, etc., can be used. The display device 20 may also have a so-called monochrome display configuration or a color display configuration. In the case of a color display configuration, one color pixel can be composed of multiple pixels; specifically, one color pixel can be composed of a set of red display pixels, green display pixels, and blue display pixels. Furthermore, it can be composed of a set of these three types of pixels plus one or more additional types of pixels. The detailed configuration of the display device 20 will be described later. Furthermore, in this embodiment, the second image 20L is described as having a lower resolution than the first image 20H, but this is not limited to this. For example, the second image 20L may have a higher resolution than the first image 20H. Also, in this embodiment, the number of images is described as 2, but this is not limited to this. For example, there may be two or more image areas, and for example, the images may be divided into three image areas for display. In addition, the display ranges of the first image 20H and the second image 20L may be fixed or changed.

[0028] The display control device 30 controls the display device 20 to display video based on digital image data captured by the imaging device 10. The display control device 30 has a gaze recognition unit 35. The gaze recognition unit 35 recognizes the direction of the observer's gaze based on eye image data captured by the eye imaging device 15 using general gaze recognition technology. For example, the gaze recognition unit 35 can recognize the pupil of the eye by binarization processing and associate its centroid position with the direction of the gaze.

[0029] The display control device 30 sets the region of the first image 20H based on the recognition result of the gaze recognition unit 35. Then, the display control device 30 generates first image data for displaying the first image 20H, which is the central field of view image, and second image data for displaying the second image 20L, which is the peripheral field of view image, based on the digital image data captured by the imaging device 10. At this time, the display device 20 can generate the first image data and the second image data with different frame rates. The display device 20 can also generate the first image data and the second image data with different display duty cycles. The display duty cycle refers to the ratio of the light emission time of the light-emitting element. Therefore, the display control device 30 according to this embodiment can transfer the first image data and the second image data to the display device 20 at different frame rates, thus reducing the amount of data transferred. Furthermore, the display control device 30 according to this embodiment can display the first image data and the second image data with different display duty cycles, thus extending the lifespan of the light-emitting element in the display device 20.

[0030] Furthermore, the digital image data may be supplied to the display control device 30 via a network, wireless communication, or the like. Alternatively, the digital image data may be supplied to the display control device 30 via a storage medium. In this case, the first image data for the first image 20H and the second image data for the second image 20L may be generated based on different digital image data. The detailed configuration of the display control device 30 will be described later. Also, in this embodiment, the digital image data may be referred to as image data. Such a display system 1 can be used in electronic devices such as computer systems, navigation systems, DVD players, Blu-ray players, home theater systems, mobile device systems, wearable device systems, and virtual / augmented reality systems, as will be described later.

[0031] Figure 3 is a block diagram showing an example configuration of the display device 20. As shown in Figure 2, the display device 20 can be applied to, for example, an organic EL (OLED) display device 20 equipped with an active matrix type drive circuit. The display device 20 comprises a display panel 200 and a control circuit (not shown) that controls the operation of the display panel 200. In this embodiment, the display panel 200 corresponds to the pixel section.

[0032] The control circuit is supplied with digital first image data synchronized with a first synchronization signal. Similarly, second image data is supplied synchronized with a second synchronization signal. The first and second image data are data that defines, for example, the grayscale level of the pixels of the image to be displayed on the display panel 200 using 8 bits. The synchronization signal includes a vertical synchronization signal, a horizontal synchronization signal, and a dot clock signal. Based on the synchronization signal, the control circuit generates various control signals and supplies them to the display panel 200. The control circuit also includes a voltage generation circuit. The voltage generation circuit supplies various potentials to the display panel 200. Furthermore, the control circuit generates an analog first image signal and an analog second image signal based on the first and second image data.

[0033] As shown in Figure 3, the display device 20 has a display panel 200, a vertical drive circuit (vertical driver) 202, and a horizontal drive circuit (horizontal driver) 204 formed on a semiconductor substrate, such as a silicon substrate. The vertical drive circuit 202 has a vertical drive circuit 202a for high resolution and a vertical drive circuit 202b for low resolution. Furthermore, the horizontal drive circuit 204 has a horizontal drive circuit 204a for high resolution and a horizontal drive circuit 204b for low resolution. In the example of Figure 3, the display panel 200 has a plurality of first pixels 200a for high resolution arranged in a matrix and a plurality of second pixels 200b for low resolution arranged in a matrix. The vertical drive circuit (vertical driver) 202 and the horizontal drive circuit (horizontal driver) 204 according to this embodiment correspond to the drive unit.

[0034] Figure 4 is a block diagram showing an example configuration of the high-resolution side of the display device 20. As shown in Figure 4, multiple scan lines from the vertical drive circuit 202a are extended horizontally to multiple first pixels 200a for high resolution, and multiple data lines from the horizontal drive circuit 204a are extended vertically.

[0035] Note that in Figure 4, only 4x5 pixels are shown for simplicity of explanation, but the display panel 200 has a total of (m1+1) x (n1+1) first pixels 200a formed on a semiconductor substrate, for example, a semiconductor layer made of silicon formed on a substrate, with m1+1 in the row direction and n1+1 in the column direction. In other words, the display panel 200 is composed of a plurality of scan lines and a plurality of data lines arranged orthogonally within the screen, and a plurality of first pixels 200a arranged at each intersection of the two lines and selectively driven via the scan lines and data lines.

[0036] The vertical drive circuit 202a is composed of, for example, a shift register circuit. When writing data signals corresponding to the grayscale level of each first pixel 200a, the vertical drive circuit 202a sequentially scans each first pixel 200a row by row by sequentially supplying a write scan signal to each scan line. Furthermore, the vertical drive circuit 202a controls the illumination / de-illumination (extinction) of each first pixel 200a by supplying a first control signal to the scan line. In addition, the vertical drive circuit 202a controls the illumination of each first pixel 200a during the non-illumination period by supplying a second control signal to the scan line. In this embodiment, examples of supplying the first control signal and the second control signal are described, but the invention is not limited thereto.

[0037] The horizontal drive circuit 204a selectively writes the signal potential (signal voltage) of the data signal corresponding to the aforementioned grayscale level and the correction potential to each data line as data signals. In other words, the signal voltage is a voltage corresponding to the grayscale level (luminance). The reference voltage is used when performing the threshold correction operation described later.

[0038] Figure 5 is a block diagram showing an example configuration of the low-resolution side of the display device 20. As shown in Figure 4, multiple scan lines from the vertical drive circuit 202b are extended horizontally to multiple second pixels 200b for low resolution, and multiple data lines from the horizontal drive circuit 204b are extended vertically.

[0039] In Figure 5, for the sake of simplicity, only a 2x2 pixel array is shown. However, the display panel 200 has a total of (m2+1)×(n2+1) second pixels 200b formed on a semiconductor substrate, for example, a semiconductor layer made of silicon formed on a substrate. These second pixels are m2+1 in the row direction and n2+1 in the column direction. That is, the display panel 200 is composed of a plurality of scan lines and a plurality of data lines arranged orthogonally within the screen, and a plurality of second pixels 200b arranged at each intersection of the two lines and selectively driven via the scan lines and data lines. In this embodiment, for example, the number of (m2+1)×(n2+1) is one-quarter of the number of (m1+1)×(n1+1). In this embodiment, the number of (m2+1)×(n2+1) is described as being less than or equal to the number of (m1+1)×(n1+1), but it is not limited to this. For example, the number of (m2+1)×(n2+1) may be configured to be greater than or equal to the number of (m1+1)×(n1+1). In this case, multiple second pixels 200b will be for high resolution, and multiple second pixels 200a will be for low resolution.

[0040] The vertical drive circuit 202b has the same function as the vertical drive circuit 202a and is composed of a shift register circuit and the like. When writing data signals corresponding to the grayscale level to each second pixel 200b, the vertical drive circuit 202b sequentially scans each second pixel 200b row by row by sequentially supplying a write scan signal to each scan line. The vertical drive circuit 202a controls the illumination / de-illumination (extinction) of each second pixel 200b by supplying a first control signal to the scan line. Furthermore, the vertical drive circuit 202b controls the second pixel 200b to not emit light during the non-illumination period by supplying a second control signal to the scan line.

[0041] The horizontal drive circuit 204b has the same functionality as the horizontal drive circuit 204a, and selectively writes the signal potential (signal voltage) of the data signal corresponding to the aforementioned grayscale level and the correction potential to each data line as data signals. In other words, the signal voltage is a voltage corresponding to the grayscale level (luminance). In this way, multiple second pixels 200b can be controlled by a control system independent of multiple first pixels 200a.

[0042] Figure 6 shows an example of the arrangement of color filters in the display device 20. As shown in Figure 6, the color filters consist of a unit comprising red filters R1-R4 for high resolution, green filters G1-G4 for high resolution, blue filters B1-B4 for high resolution, and red, green, and blue filters RL1, GL1, and BL1 for low resolution.

[0043] Figure 7 schematically shows the light-emitting elements 200c corresponding to the red filters R1-R4, green filters G1-G4, blue filters B1-B4, and red, green, and blue filters RL1, GL1, and BL1 shown in Figure 6 as triangles, and the corresponding pixels 200a and 200b as rectangles. In other words, Figure 7 schematically shows an example of the circuit configuration for one unit shown in Figure 6. As shown in Figure 7, the light-emitting elements 200c controlled by the first pixel 200a are associated with the red filters R1-R4, green filters G1-G4, and blue filters B1-B4, and the light-emitting elements 200c controlled by the second pixel 200b are associated with the red, green, and blue filters RL1, GL1, and BL1. As a result, the red filters R1-R4, green filters G1-G4, and blue filters B1-B4 can be individually controlled by the first pixel 200a. Furthermore, the red, green, and blue filters RL1, GL1, and BL1 can be individually controlled by the second pixel 200b.

[0044] As shown again in Figure 2, the combination of color filters to be illuminated may differ between the display range of the first image 20H and the display range of the second image 20L, which has a lower resolution than the first image 20H. For example, in the display range of the first image 20H, only the high-resolution green filters G1 to G4 may be illuminated. On the other hand, in the display range of the first image 20H, the high-resolution red filters R1 to R4 and blue filters B1 to B4 may not be illuminated, and instead only the low-resolution red and blue filters RL1 and BL1 may be illuminated. In this case, in the display range of the second image 20L, the low-resolution red, green, and blue filters RL1, GL1, and BL1 may be illuminated.

[0045] Furthermore, the arrangement of color filters is not limited to these examples. Instead of the red filters R1-R4 for high resolution, the green filters G1-G4 for high resolution may be used, and instead of the blue filters B1-B4 for high resolution, the green filters G1-G4 for high resolution may be used. The human eye's sensitivity to green is higher than that to red and blue, and by emitting the green filters G1-G4 for high resolution in the display range of the first image 20H, more efficient emission control becomes possible. In this way, it is possible to use different combinations of color filters for the display range of the first image 20H and the display range of the second image 20L, which has a lower resolution than the first image 20H.

[0046] Figure 8 shows an example configuration of the first pixel 200a and the corresponding light-emitting element 200c. The light-emitting element 200c is, for example, an OLED, which is a light-emitting element in which a white organic EL layer is sandwiched between an anode and a light-transmitting cathode on a silicon substrate. As shown in Figure 8, the first pixel 200a is connected to the first scan line 5, second scan line 6 and third scan line 7 from the vertical drive circuit 202a and the data line 8 from the horizontal drive circuit 204a. That is, the scan lines in Figure 4 described above have the first scan line 5, the second scan line 6 and the third scan line 7. Similarly, the data line in Figure 4 described above has the data line 8.

[0047] The second pixel 200b has the same configuration as the first pixel 200a. As shown in Figure 8, the first pixel 200b is connected to the first scan line 5, second scan line 6, and third scan line 7 from the vertical drive circuit 202b, and to the data line 8 from the horizontal drive circuit 204a. That is, the scan lines in Figure 5 described above have the first scan line 5, the second scan line 6, and the third scan line 7. Similarly, the data line in Figure 5 described above has the data line 8. In the following description, the explanation of the second pixel 200b is the same as that of the first pixel 200a, so the explanation will be omitted.

[0048] The first pixel 200a contains four transistors (driver transistor DRTr, transistor WSTr, transistor DSTr, and transistor AZTr), a holding capacitor Cs, an auxiliary capacitor Csub, and an OLED. These four transistors are P-channel type transistors. In other words, the first pixel 200a is composed of Pch4Tr2C.

[0049] The drive transistor DRTr has its source connected to the feed line 41 via transistor DSTr, and its drain connected to the anode of the OLED, controlling the current flowing through the OLED. A high-potential power supply (VCCP) is supplied to the feed line 41. The cathode of the OLED is connected to the power supply line 42 to form a common electrode and is set to a low-potential power supply (Vss).

[0050] The transistor WSTr has its gate connected to the first scan line 5, one of its source and drain connected to the data line 8, and the other connected to the gate of the drive transistor DRTr. The transistor WSTr writes the data line potential (gradation potential) to the gate of the drive transistor DRTr in response to the write scan signal WS.

[0051] The DSTr transistor (second transistor) has its gate connected to the second scan line 6, one of its source and drain connected to the power supply line 41, and the other connected to the source of the DRTr drive transistor, controlling the power supply to the DRTr drive transistor.

[0052] The first transistor AZTr has its gate connected to the third scan line 7, one of its source and drain is connected to the drain of the drive transistor DRTr and the anode of the OLED, and the other is connected to the power line 42.

[0053] The retaining capacitance Cs is connected between the gate and source of the drive transistor DRTr and maintains the gate-source voltage Vgs of DRTr. The auxiliary capacitance Csub is connected between the source of the drive transistor DRTr and the node of the fixed power supply (Vss) and suppresses fluctuations in the source voltage of the drive transistor DRTr, while also acting to set the gate-source voltage Vgs of the drive transistor DRTr to the threshold voltage Vth of the drive transistor DRTr.

[0054] As explained in Figure 6, a unit consists of high-resolution red filters R1-R4, high-resolution green filters G1-G4, high-resolution blue filters B1-B4, and low-resolution red, green, and blue filters RL1, GL1, and BL1. In this case, each first pixel 200a and each second pixel 200b corresponding to these color filters may also be arranged in accordance with these color filters. Alternatively, some of the circuit components constituting the first pixel 200a and the second pixel 200b may be arranged in accordance with the color filters. For example, any of the drive transistors DRTr, WSTr, DSTr, and AZTr constituting the first pixel 200a and the second pixel 200b may be arranged in accordance with the positions of these color filters. By arranging the circuit configuration in accordance with the positions of the color filters, it becomes possible to make the circuit layout more efficient.

[0055] In the display device 20, the luminescence brightness of the OLED, which is a light-emitting element 200c, is controlled by a current controlled by a drive transistor DRTr in each first pixel 200a. Therefore, if the threshold voltage Vth of the drive transistor DRTr varies in each first pixel 200a, the luminescence brightness will vary from pixel to pixel, and the uniformity of the screen will be lost. To address this, the display device 20 performs a Vth correction operation in conjunction with line sequential scanning to reduce the variation in luminescence brightness caused by variations in the threshold voltage Vth of the drive transistor DRTr.

[0056] The period for Vth correction of the drive transistor DRTr consists of a Vth correction preparation period and a Vth correction period. Vth correction preparation refers to initializing the gate voltage and source voltage of the drive transistor DRTr. Vth correction refers to the correction operation that brings the gate-source voltage Vgs of the drive transistor DRTr closer to the threshold voltage Vth of the drive transistor DRTr.

[0057] Figure 9 shows an example of the driving timing of the first pixel 200a from the Vth correction preparation period of the driving transistor DRTr to the writing of the data signal according to the grayscale level. First, the Vth correction preparation period begins when a new field of line sequential scanning is entered. During the Vth correction preparation period, the reference voltage Vofs is written to the data line 8 by the horizontal driving circuit 204a. In this state, the writing scan signal WS from the vertical driving circuit 202a turns on the transistor WSTr (see Figure 8), and the gate voltage Vg of the driving transistor DRTr becomes the reference voltage Vofs and is initialized (reset). At this time, the first control signal DS from the vertical driving circuit 202a turns on the transistor DSTr, and the source voltage of the driving transistor DRTr becomes the power supply voltage VCCP and is initialized (reset). This completes the Vth correction preparation.

[0058] Once the Vth correction preparation is complete, the Vth correction period begins. During the Vth correction period, the transistor DSTr is turned off by the first control signal DS from the vertical drive circuit 202a. This causes the source voltage of the drive transistor DRTr to start to decrease, and the gate-source voltage Vgs converges to the threshold voltage Vth. This voltage corresponding to the threshold voltage Vth is held in the retaining capacitance Cs. During the Vth correction period, the horizontal drive circuit 204a switches the write voltage to data line 8 from the reference voltage Vofs to the signal voltage Vdata.

[0059] By holding a voltage equivalent to the threshold voltage Vth in the retaining capacitance Cs, the dependence of the drain-source current Ids flowing through the drive transistor DRTr on the threshold voltage Vth can be suppressed when the drive transistor DRTr is driven by the signal voltage Vdata.

[0060] Figure 10 shows an example configuration of the second pixels 200a and 200b. Figure 11 similarly shows an example configuration of the third pixels 200a and 200b. Figure 12 similarly shows an example configuration of the fourth pixels 200a and 200b. Figure 13 similarly shows an example configuration of the fifth pixels 200a and 200b. As shown in Figures 10 to 13, the configuration of pixels 200a and 200b is not limited as long as the light-emitting element 200c can be controlled according to the control of the scan lines and data lines. Furthermore, pixels 200a and 200b may be configured with different structures.

[0061] The above describes the configuration of this embodiment, and below we will describe an example of processing. Figure 14 is a flowchart of an example of processing according to the first embodiment. As shown in Figure 14, first the control device 30 acquires motion image data captured by the imaging device 10 and image data acquired by the eye imaging device 15 (step S100). Next, the gaze recognition unit 35 of the control device 30 recognizes the direction of the observer's gaze based on the image data acquired by the eye imaging device 15. Then, the control device 30 sets the range of the first image data (step S102) and generates the first image data and the second image data (step S104).

[0062] Next, the control circuit of the display device 20 is supplied with the first image data in synchronization with the first synchronization signal. Similarly, the second image data is supplied in synchronization with the second synchronization signal. The vertical drive circuit 202a and the horizontal drive circuit 204a for high resolution control the display of the first image data in synchronization with the first synchronization signal (step S106). On the other hand, the vertical drive circuit 202b and the horizontal drive circuit 204b for low resolution control the display of the second image data in synchronization with the second synchronization signal, independently of the first synchronization signal (step S108).

[0063] Next, the control device 30 determines whether or not to terminate the display (step S110). If it determines not to terminate (step S110, n), it repeats the process from step S100. If it determines to terminate (step S110, y), it terminates the entire process.

[0064] As described above, according to this embodiment, a plurality of first pixels 200a for high resolution and a plurality of second pixels 200b for low resolution are configured independently. The plurality of first pixels 200a for high resolution are controlled by a vertical drive circuit 202a and a horizontal drive circuit 204a for high resolution, and the plurality of second pixels 200b for low resolution are controlled by a vertical drive circuit 202b and a horizontal drive circuit 204b for low resolution. As a result, a high-resolution first image 20H and a low-resolution second image 20L can be displayed on the display device 20 by independent control systems.

[0065] (Second Embodiment) The display system 1 according to the second embodiment differs from the display system 1 according to the first embodiment in that multiple light-emitting elements 200c are shared by multiple pixels 200a for high resolution and multiple pixels 200b for low resolution. The differences from the display system 1 according to the first embodiment will be explained below.

[0066] Figure 15 shows an example of the arrangement of color filters in the display device 20 according to the second embodiment. As shown in Figure 15, the color filters consist of a unit comprising high-resolution red filters R1 to R4, high-resolution green filters G1 to G4, and high-resolution blue filters B1 to B4.

[0067] Figure 16 shows the light-emitting elements 200c corresponding to the red filters R1-R4, green filters G1-G4, and blue filters B1-B4 shown in Figure 15 as triangles, and the corresponding pixels 200a and 200b schematically as rectangles. As shown in Figure 16, each of the red filters R1-R4, green filters G1-G4, and blue filters B1-B4 is associated with a light-emitting element 200c whose emission is controlled by the respective first pixel 200a. Furthermore, one second pixel 200b is connected to each of the red filters R1-R4, one second pixel 200b is connected to each of the green filters G1-G4, and one second pixel 200b is connected to each of the blue filters B1-B4. In addition, a diode 300 is placed between the second pixel 200b and the light-emitting element 200c, which allows current to flow in the direction of the light-emitting element 200c. This diode 300 suppresses reverse current flow. This suppresses the transmission of the control current from the first pixel 200a to the second pixel 200b. As a result, even if the light-emitting element 200c is shared by the first pixel 200a and the second pixel 200b, interference in the light emission control of the light-emitting element 200c between the first pixel 200a and the second pixel 200b is suppressed. In this embodiment, the diode 300 corresponds to a rectifier element.

[0068] In this way, each first pixel 200a controls the light emission of one corresponding light-emitting element 200c, thus maintaining high resolution. However, because a diode is present, the supply of current to other light-emitting elements 200c via the light-emitting element 200c and the second pixel 200b is suppressed. On the other hand, each second pixel 200b controls the light emission of four corresponding light-emitting elements 200c, resulting in low resolution.

[0069] Figure 17 shows an example configuration of the first pixel 200a and the second pixel 200b shown in Figure 16. Here, a portion of the first pixel 200a corresponding to the red filters R1 to R4 and the second pixel 200b corresponding to the red filters R1 to R4 are shown. As shown in Figures 16 and 17, the light-emitting element 200c is shared by the first pixel 200a and the second pixel 200b. Therefore, the second pixel 200b can be configured without having a light-emitting element 200c.

[0070] As described above, according to this embodiment, multiple light-emitting elements 200c are shared between multiple pixels 200a for high resolution and multiple pixels 200b for low resolution. This eliminates the need for a color filter and corresponding light-emitting elements 200c for low resolution, making it possible to further simplify the configuration of the display device 20.

[0071] (Third embodiment) The display system 1 according to the third embodiment differs from the display system 1 according to the second embodiment in that the red filters R1-R4, green filters G1-G4, and blue filters B1-B4 are configured in a honeycomb structure. The differences from the display system 1 according to the second embodiment will be explained below.

[0072] Figure 18 shows an example of the arrangement of color filters in the display device 20 according to the third embodiment. As shown in Figure 18, the color filters consist of red filters R1 to R4 for high resolution, green filters G1 to G4 for high resolution, and blue filters B1 to B4 for high resolution, all arranged in a honeycomb structure. The centroid G10 is the centroid of all filters, G12 is the centroid of filters R1, G1, and B1, G14 is the centroid of filters R2, G2, and B2, G16 is the centroid of filters R3, G3, and B3, and G18 is the centroid of filters R4, G4, and B4.

[0073] Figure 19 shows the light-emitting elements 200c corresponding to the red filters R1-R4, green filters G1-G4, and blue filters B1-B4 shown in Figure 18 as triangles, and the corresponding pixels 200a and 200b schematically as rectangles. As shown in Figure 19, each of the red filters R1-R4, green filters G1-G4, and blue filters B1-B4 is associated with a light-emitting element 200c whose emission is controlled by the respective first pixel 200a. Furthermore, one second pixel 200b is connected to the light-emitting element 200c corresponding to the red filter R4, one second pixel 200b is connected to the light-emitting element 200c corresponding to the green filter G1, and one second pixel 200b is connected to the light-emitting elements 200c corresponding to the blue filters B2 and B3. In addition, a diode 300 that allows current to flow in the direction of the light-emitting element 200c is placed between the second pixel 200b and the light-emitting elements 200c corresponding to the blue filters B2 and B3.

[0074] Figure 20 shows a different connection example from Figure 19. The light-emitting elements 200c corresponding to the red filters R1-R4, green filters G1-G4, and blue filters B1-B4 shown in Figure 18 are shown as triangles, and the corresponding pixels are schematically shown as rectangles. As shown in Figure 20, each of the red filters R1-R4, green filters G1-G4, and blue filters B1-B4 is associated with a light-emitting element 200c whose emission is controlled by the respective first pixel 200a. Furthermore, one second pixel 200b is connected to the red filter R4, one second pixel 200b is connected to the green filter G1, and one second pixel 200b is connected to the blue filter B3.

[0075] Figure 21 shows examples of light emission using the connection example in Figure 19 and the connection example in Figure 20. As shown in Figure 21A, when the red filter R4, green filter G1, blue filters B2 and B3 are illuminated by a single second pixel 200b, it coincides with the centroid G10 of the entire filter. On the other hand, as shown in Figure 21B, when the red filter R4, green filter G1, and blue filter B2 are illuminated by a single second pixel 200b, the centroid G10 of the entire filter shifts to the centroid G10a. In this way, when the blue filters B2 and B3 are illuminated, it coincides with the centroid G10, thus suppressing image fluctuations in display at both low and high resolutions. On the other hand, when only the blue filter B2 is illuminated, the diode 300 is unnecessary.

[0076] As described above, the red filters R1-R4, green filters G1-G4, and blue filters B1-B4 in this embodiment are configured with a honeycomb structure. This makes it possible to make the centroid 10 of the illuminated filters coincide with the centroid 10 of the filters used when displaying high-resolution images, even without illuminating all the filters when displaying low-resolution images.

[0077] (Fourth Embodiment) The display system 1 according to the fourth embodiment differs from the display system 1 according to the second embodiment in that, when multiple light-emitting elements 200c are shared between multiple first pixels 200a for high resolution and multiple second pixels 200b for low resolution, a portion of the circuit configuration of the second pixels 200b is shared with the first pixels 200a. The differences from the display system 1 according to the second embodiment will be explained below.

[0078] Figure 22 shows the configuration of the first pixel 200a corresponding to red filters R1 and R2, and the configuration of the second pixel 200b corresponding to red filters R1 to R4, in the connection example shown in Figure 16. In other words, the configuration of the first pixel 200a corresponding to red filters R3 and R4 is omitted in Figure 22. As shown in Figure 22, the transistors DS and AZ1 of the second pixel 200b are shared with the first pixel 200a.

[0079] Figure 23 shows an example configuration of the vertical drive circuit 202 in the configuration example shown in Figure 22. As shown in Figure 23, it differs from the display system 1 according to the second embodiment in that it further has a vertical drive circuit 202c. The vertical drive circuit 202c generates the gate signals for the shared second pixel 200b transistors DS and AZ1. This eliminates the need to duplicate the shift register and other components of the vertical drive circuit 202, making the vertical drive circuit 202 more compact.

[0080] Figure 24 shows the configuration of the first pixel 200a corresponding to red filters R1 and R2, and the configuration of the second pixel 200b corresponding to red filters R1 to R4, in the connection example shown in Figure 16. In Figure 24, transistors DS and AZ1 are examples of those present in both the first pixel 200a and the second pixel 200b. In this case as well, the gate signals of the first pixel 200a and the second pixel 200b can be shared by the vertical drive circuit 202c. Therefore, it is not necessary to duplicate the shift register and other components of the vertical drive circuit 202, and the vertical drive circuit 202 can be made smaller.

[0081] As described above, according to this embodiment, the gate signals of the first pixel 200a, the second pixel 200b, and the multiple transistors DS and AZ1 are controlled by a shared signal of the vertical drive circuit 202c. This eliminates the need to duplicate the shift register and other components of the vertical drive circuit 202, making the vertical drive circuit 202 more compact. Furthermore, although this embodiment was described using an example of color filter arrangement, the arrangement of the first pixel 200a and the second pixel 200b corresponding to the color filter may be arranged in the same way as the color filter. Alternatively, the arrangement of a part of the circuit configuration of the first pixel 200a and the second pixel 200b corresponding to the color filter may be arranged in the same way as the color filter. Moreover, the arrangement examples in this embodiment are just examples and are not limited to these; different combinations of circuit configuration and color filter arrangement are possible.

[0082] (electronic equipment) The following describes specific examples of electronic devices and other devices that utilize the display device 20 according to this embodiment as a display unit. (Specific example 1) Figures 25A and 25B show an example of the external appearance of the digital still camera 310. This digital still camera 310 is a single-lens reflex type with interchangeable lenses, and has an interchangeable shooting lens unit (interchangeable lens) 312 located approximately in the center of the front of the camera body 311, and a grip section 313 for the photographer to hold on the left side of the front.

[0083] A monitor 314 is provided on the back of the camera body 311, slightly to the left of the center. An electronic viewfinder (eyepiece) 315 is provided above the monitor 314.

[0086] (Specific example 4) Figure 28 is an external view of the see-through head-mounted display. The see-through head-mounted display 611 consists of a main body 612, an arm 613, and a lens barrel 614. The main body 612 is connected to the arm 613 and the glasses 600. Specifically, the long side end of the main body 612 is connected to the arm 613, and one side of the main body 612 is connected to the glasses 600 via a connecting member. The main body 612 may also be directly attached to the head of a person.

[0087] The main body 612 houses a control board for controlling the operation of the see-through head-mounted display 511, as well as a display unit. The arm 613 connects the main body 612 to the lens barrel 614 and supports the lens barrel 614. Specifically, the arm 613 is connected to the end of the main body 612 and the end of the lens barrel 614, respectively, and fixes the lens barrel 614 in place. The arm 613 also houses signal lines for communicating image-related data provided from the main body 612 to the lens barrel 614.

[0088] The microscope tube 614 projects image light, provided from the main body 612 via the arm 613, through the eyepiece towards the eyes of the user wearing the see-through head-mounted display 611. In this see-through head-mounted display 611, the display device 20 of this disclosure can be used in the display section of the main body 612.

[0089] (Specific example 5)

[0090] For example, the display device 20 according to this embodiment can be applied to the display unit of an electronic device such as a smartphone. Specifically, as shown in Figure 29, the smartphone 600 has a display unit 602 that displays various information, and an operation unit consisting of buttons, etc. that accept user input. The display unit 602 can be the display device 20 according to this embodiment.

[0091] (Specific example 6)

[0092] The display device 20 according to this disclosure can be used for various purposes. Figures 30 and 31 show the internal configuration of a vehicle 100, which is a first application example of an electronic device equipped with the display device 20 according to this disclosure. Figure 30 shows the interior of the vehicle 100 from the rear to the front, and Figure 31 shows the interior of the vehicle 100 from the diagonal rear to the diagonal front.

[0093] The vehicle 100 in Figures 30 and 31 includes a center display 101, a console display 102, a head-up display 103, a digital rear mirror 104, a steering wheel display 105, and a rear entertainment display 106.

[0094] The center display 101 is positioned on the dashboard 107, facing the driver's seat 108 and the passenger seat 109. Figure 38 shows an example of a horizontally elongated center display 101 extending from the driver's seat 108 to the passenger seat 109, but the screen size and placement of the center display 101 are arbitrary. The center display 101 can display information detected by various sensors 500. As a specific example, the center display 101 can display images captured by an image sensor, distance images to obstacles in front of and to the sides of the vehicle measured by a ToF sensor 500, and the body temperature of passengers detected by an infrared sensor 500. The center display 101 can be used to display at least one of the following: safety-related information, operation-related information, life logs, health-related information, authentication / identification-related information, and entertainment-related information.

[0095] Safety-related information includes information such as drowsiness detection, distraction detection, detection of mischief by a passenger, seatbelt wearing status, and detection of an unattended occupant, and is detected by a sensor 500 placed on top of the back of the center display 101. Operation-related information is detected by sensing gestures related to occupant operation using the sensor 500. The detected gestures may include operation of various equipment within the vehicle 100. For example, operation of air conditioning equipment, navigation system, AV equipment, lighting equipment, etc. is detected. Lifelogs include lifelogs of all occupants. For example, lifelogs include records of each occupant's actions while riding. By acquiring and saving lifelogs, it is possible to confirm the state of the occupants at the time of an accident. Health-related information is detected by sensing the occupant's body temperature using a temperature sensor 500 and inferring the occupant's health status based on the detected body temperature. Alternatively, the occupant's face may be captured using an image sensor, and the occupant's health status may be inferred from the captured facial expression. Furthermore, the system may engage in automated voice conversations with the occupants and infer their health status based on their responses. Authentication / identification-related information includes a keyless entry function that uses the sensor 500 for facial recognition, and an automatic seat height and position adjustment function based on facial recognition. Entertainment-related information includes a function that uses the sensor 500 to detect information on how the occupants operate the AV equipment, and a function that uses the sensor 500 to recognize the occupants' faces and provide content suitable for the occupants through the AV equipment.

[0096] The console display 102 can be used, for example, to display life log information. The console display 102 is located near the shift lever 111 on the center console 110 between the driver's seat 108 and the passenger seat 109. The console display 102 can also display information detected by various sensors 500. In addition, the console display 102 may display images of the area around the vehicle captured by the image sensor, or distance images to obstacles around the vehicle.

[0097] The head-up display 103 is virtually displayed behind the windshield 112 in front of the driver's seat 108. The head-up display 103 can be used to display at least one of the following: safety-related information, operation-related information, life logs, health-related information, authentication / identification-related information, and entertainment-related information. Because the head-up display 103 is often virtually positioned in front of the driver's seat 108, it is suitable for displaying information directly related to the operation of the vehicle 100, such as the vehicle's speed and fuel (battery) level.

[0098] The digital rearview mirror 104 can not only display the area behind the vehicle 100, but also display the situation of the passengers in the rear seat. By placing the sensor 500 on top of the back of the digital rearview mirror 104, it can be used, for example, to display life log information.

[0099] The steering wheel display 105 is positioned near the center of the steering wheel 113 of the vehicle 100. The steering wheel display 105 can be used to display at least one of the following: safety-related information, operation-related information, life log, health-related information, authentication / identification-related information, and entertainment-related information. In particular, because the steering wheel display 105 is located near the driver's hands, it is suitable for displaying life log information such as the driver's body temperature, or information related to the operation of AV equipment, air conditioning equipment, etc.

[0100] The rear entertainment display 106 is mounted on the back of the driver's seat 108 and the passenger seat 109, and is intended for viewing by rear-seat passengers. The rear entertainment display 106 can be used to display at least one of the following: safety-related information, operation-related information, life logs, health-related information, authentication / identification-related information, and entertainment-related information. In particular, because the rear entertainment display 106 is in front of the rear-seat passengers, it displays information relevant to them. For example, it may display information related to the operation of AV equipment or air conditioning equipment, or it may display the results of measurements of the rear-seat passengers' body temperature taken by the temperature sensor 500.

[0101] As described above, by placing the sensor 500 on top of the back side of the display device 20, the distance to surrounding objects can be measured. Optical distance measurement methods can be broadly divided into passive and active types. Passive methods measure distance by receiving light from an object without projecting light from the sensor 500 onto the object. Passive methods include the lens focusing method, stereo method, and monocular method. Active methods measure distance by projecting light onto an object and receiving the reflected light from the object with the sensor 500. Active methods include the optical radar method, active stereo method, illuminance difference stereo method, moiré topography method, and interferometry method. The display device 20 according to this disclosure is applicable to any of these distance measurement methods. By using the sensor 500 placed on top of the back side of the display device 20 according to this disclosure, the passive or active distance measurement described above can be performed.
