1 to 3, a display device 100 according to an embodiment of the present invention includes a display panel 110, an optical module 120, a panel driver 130, an optical driver 140, and a controller 150. And a memory 160.

The display panel 110 includes a plurality of pixels and displays a color image. The display panel 110 may be implemented as an organic light emitting display panel, a liquid crystal display panel, a plasma display panel, a quantum dot light emitting display panel, or an electrophoretic display panel.

The display panel 110 may be divided into a display area DA where pixels are formed to display an image and a non-display area NDA that does not display an image.

The non-display area NDA may be disposed to surround the display area DA. In the non-display area NDA, a panel driver 130 for supplying various signals to a plurality of signal wires in the display area DA, and a link part for connecting the panel driver 130 and the plurality of signal wires (not shown) And the like can be formed.

A plurality of pixels are disposed in the display area DA to display an image. The display area DA includes a first display area DA1 and a second display area DA2, as shown in FIG. 2.

The first display area DA1 does not overlap with the area CA where the optical module 120 is disposed, and is an area that displays an image regardless of whether the optical module 120 is operated. The first display area DA1 may be formed to have a wide area.

A plurality of first pixels P1 including at least two or more first sub-pixels SP1 may be provided in the first display area DA1. The plurality of first pixels P1 may include light emitting pixels. Specifically, at least two or more first sub-pixels SP1 included in the first pixel P1 may be light-emitting sub-pixels that are provided with a light-emitting element to emit predetermined color light. The first pixel P1 may include at least two of a red sub-pixel emitting red light, a green sub-pixel emitting green light, and a blue sub-pixel emitting blue light. For example, the first pixel P1 may include a red sub-pixel and a green sub-pixel, and the adjacent first pixel P1 may include a blue sub-pixel and a green sub-pixel. For another example, the first pixel P1 may include a red sub-pixel, a green sub-pixel, and a blue sub-pixel.

The second display area DA2 overlaps the area CA where the optical module 120 is disposed, and an image to be displayed may be determined according to whether the optical module 120 is operated. Specifically, when the optical module 120 does not operate, the second display area DA2 may display an image together with the first display area DA1. On the other hand, when the optical module 120 operates in the second display area DA2, an image may not be displayed or a black image may be displayed. In this case, an image may be displayed on the first display area DA1.

The size, position, and shape of the second display area DA2 may be determined in consideration of the optical module 120. The second display area DA2 may be provided at a position corresponding to the optical module 120. In addition, the second display area DA2 may have a size including the area CA in which the optical module 120 is disposed.

Unlike the first display area DA1, in the second display area DA2, the plurality of second pixels P2 may include an emission pixel and a non-emission pixel. The light-emitting pixel may be a region in which a light-emitting element is provided to emit light, and the non-emission pixel may be a region through which external light is transmitted without a light-emitting element. In other words, unlike the first display area DA1, the second display area DA2 may include an area through which external light is transmitted without a light emitting device.

Among the second pixels P2, at least two or more second sub-pixels SP2 included in the light-emitting pixel may be light-emitting sub-pixels provided with a light-emitting element to emit predetermined color light.

As a result, in the second display area DA2, the number of light emitting sub-pixels provided in the unit pixel area UPA may be smaller than that of the first display area DA1. For example, as shown in FIG. 3, the second display area DA2 includes four light-emitting sub-pixels in the unit pixel area UPA, while the first display area DA1 includes 16 light-emitting sub-pixels in the unit pixel area UPA. Three light-emitting sub-pixels may be provided.

The light transmittance of the second display area DA2 may vary depending on the number of light-emitting sub-pixels provided in the unit pixel area UPA. When the number of light emitting sub-pixels provided in the unit pixel area UPA increases, the luminance and resolution of the second display area DA2 may increase, but the light transmittance of the second display area DA2 may decrease. Meanwhile, when the number of light-emitting sub-pixels provided in the unit pixel area UPA decreases, the luminance and resolution of the second display area DA2 decreases, but the light transmittance of the second display area DA2 may increase. In the display panel 110 according to an exemplary embodiment, the number of light emitting sub-pixels may be determined in consideration of the luminance, resolution, and light transmittance of the second display area DA2.

As described above, the first display area DA1 and the second display area DA2 may have different transmittances and resolutions. The first display area DA1 may have a first transmittance, and the second display area DA2 may have a second transmittance higher than the first transmittance. Also, the first display area DA1 may have a first resolution, and the second display area DA2 may have a second resolution smaller than the first resolution.

The optical module 120 may be an illuminance sensor, a fingerprint sensor, or the like.

The panel driver 130 controls driving of the display panel 110 by receiving a control signal from the controller 150. To this end, the panel driver 130 includes a gate driver and a data driver.

The gate driver generates gate signals for driving the gate lines of the display panel 110 in response to a gate control signal input from the controller 150. The gate driver supplies the generated gate signals to the sub-pixels SP1 and SP2 of each of the pixels P1 and P2 included in the display panel 110 through gate lines.

The data driver receives a data control signal and an image data signal from the controller 150. The data driver converts a digital image data signal into an analog image data signal in response to a data control signal input from the controller 150. The data driver supplies the converted image data signal to the sub-pixels SP1 and SP2 of each of the pixels P1 and P2 included in the display panel 110 through data lines.

The optical driver 140 controls driving of the optical module 120 by receiving a control signal from the controller 150.

The luminance adjuster 363 may adjust the image data for an area of the second display area DA2 excluding the boundary area BA to have a second luminance different from the first luminance.

For example, the second luminance may be higher than the first luminance. Since the second display area DA2 includes a non-emission pixel or a non-emission sub-pixel, the resolution is smaller than that of the first display area DA1.
