[0076] The main body (10a) may further include a bezel that covers the edges of the display panel (100). In this case, the cover and the bezel of the main body of the display device may be detachably connected to each other.

[0077] The display panel (100) may also include a plurality of display modules (101, 102, 103). The plurality of display modules (101, 102, 103) may be arranged in a quadrangle type, such as a rectangle (Rectangle type) or a square (Square type).

[0078] Multiple display modules (101, 102, 103) can be arranged vertically and horizontally so as to be adjacent to each other. Multiple display modules (101, 102, 103) can be arranged in a row, column, or matrix form. There are no restrictions on the number of multiple display modules or the arrangement method.

[0079] Multiple display modules (101, 102, 103) may have the same structure as each other.

[0080] Each of the plurality of display modules (101, 102, 103) may include a plurality of light sources ranging from several μm to tens of μm. Each of the plurality of display modules (101, 102, 103) may include a plurality of light sources ranging from hundreds of μm. Here, the light sources ranging from several μm to tens of μm and the light sources ranging from hundreds of μm may include light-emitting diodes (LEDs).

[0081] Each of the plurality of display modules (101, 102, 103) may include a plurality of light sources with a micro-unit size ranging from a few μm to several hundred μm. In this case, the plurality of light sources may include a plurality of first light sources (111) with a size ranging from a few μm to several tens of μm and second light sources (112) with a size of several hundred μm. Here, the plurality of first light sources (111) may include micro light-emitting diodes (micro LEDs). The plurality of second light sources (121) may include mini light-emitting diodes (mini LEDs).

[0083] As illustrated in FIG. 2, a plurality of display modules (101, 102, 103) arranged in a row can be arranged such that the positions of the second light source (121) are offset between adjacent rows. FIG. 2 is merely a drawing of an example of an arrangement of a plurality of display modules, and the arrangement of the plurality of display modules is not limited thereto.

[0084] In this embodiment, the display panel is described as a single display panel rather than being divided into multiple display modules.

[0085] As illustrated in FIG. 2, each of the first light sources (111) and the second light sources (121) may include a first, second, and third light-emitting element. For example, the first light-emitting element may be a device that emits red light, the second light-emitting element may be a device that emits green light, and the third light-emitting element may be a device that emits blue light.

[0086] The first, second, and third light-emitting elements can form a single pixel. The single pixel may include a first sub-pixel (R), a second sub-pixel (G), and a third sub-pixel (B).

[0087] In this embodiment, the first and second light sources of a horizontal structure formed horizontally with respect to the plane direction of the display panel (100) have been described, but it is also possible to implement the first and second light sources of a vertical structure formed vertically with respect to the plane direction of the display panel (100) with respect to the first, second, and third subpixels.

[0088] Multiple first light sources (111) may be arranged adjacent to each other, but may be arranged vertically and horizontally. For example, multiple first light sources (111) may be arranged in the form of an M*N matrix. Here, M and N may be natural numbers.

[0089] The first distance (d1), which is the left-right distance between adjacent first light sources (111), may be the same. The second distance (d2), which is the up-down distance between adjacent first light sources (111), may be the same. Here, the first distance (d1) and the second distance (d2) may be the same or different.

[0090] Multiple second light sources (121) may be arranged between each of the multiple first light sources (111). Multiple second light sources (121) may be arranged spaced apart from each other.

[0091] When multiple display modules are arranged in a row, the second light sources (121) among the multiple second light sources arranged in odd rows may be arranged in first positions corresponding to each other vertically. The second light sources among the multiple second light sources (121) arranged in even rows may be arranged in second positions corresponding to each other vertically.

[0093] The third distance (d3), which is the left-right distance between two adjacent second light sources among a plurality of second light sources arranged in the same row, can be equal to each other.

[0094] Among the multiple second light sources arranged in odd rows, the fourth distance (d4), which is the vertical distance between second light sources arranged adjacent to each other at positions corresponding to each other vertically, may be equal to each other.

[0095] Among the multiple second light sources arranged in an even row, the fourth distance (d4), which is the vertical distance between second light sources arranged adjacent to each other at positions corresponding to each other vertically, may be equal to each other.

[0098] The second light sources arranged in odd rows and the second light sources arranged in even rows may be arranged offset from each other with respect to the left and right directions. For example, among the plurality of second light sources (121), the second light sources arranged in even rows may be arranged at a center position (d3 / 2) between the second light sources arranged in the even rows and the second light sources arranged in the adjacent odd rows.

[0099] The second light sources arranged in odd rows and the second light sources arranged in even rows may be arranged so as to be offset from each other in the vertical direction. For example, among the plurality of second light sources (121), the second light sources arranged in even rows may be arranged at a central position (d4 / 2) between the second light sources arranged in the even row and the second light sources arranged in the adjacent odd row.

[0100] As illustrated in FIG. 3, the display panel (100) may include a first panel (110) having a plurality of first light sources (111) and a plurality of through holes (112), and a second panel (120) having a plurality of second light sources (121) provided on one side of the first panel (110).

[0105] The light source surface (120a) of the second panel (120) on which the second light sources are provided may be provided adjacent to the second panel surface (110b) of the first panel. The light source surface (120a) of the second panel (120) on which the second light sources are provided may be in contact with the second panel surface (110b) of the first panel.

[0157] The power pad (127) can supply power greater than that supplied to the plurality of first light sources provided in the first pad to the plurality of second light sources (121).

[0158] The power pad (127) can be made of low-resistance metal (Cu).

[0159] The second panel (120) is made of a printed circuit board, and by configuring the power pad with low-resistance metal, the IR drop can be minimized when high current is applied to the second light sources.

[0160] As illustrated in FIG. 10, the display panel (110) of the present embodiment can be electrically connected to the first panel (110) and the second panel (120) by contact between the first connection pad (113) of the first panel (110) and the second connection pad (122) of the second panel (120).

[0161] By contact between the first connection pad (113) of the first panel (110) and the second connection pad (122) of the second panel (120), high power from the power pad (127) of the second panel (120) can be supplied to the circuit plate (115) of the first panel (110), and a plurality of second light sources (121) provided on the second pad can be operated by the driving operation of the second driving circuit provided on the circuit plate (115) of the first panel (110) using the high power from the power pad (127).

[0162] The first panel (110) can operate multiple first light sources (111) using a power source with low power relative to the power of the power pad (127).

[0163] The display panel (110) of the present embodiment can emit first light sources (111) at a first brightness (Br1) and can emit second light sources (121) at a second brightness (Br2) that is brighter than the first brightness (Br1).

[0165] The number of first light sources (111) provided in the first panel (110) may be greater than the number of second light sources (121) provided in the second panel (120). That is, the first panel (110) can display a high-resolution image, and the second panel (120) can display a low-resolution image.

[0166] In summary, the first panel (110) may be a panel for displaying an image of a first resolution and a first brightness. The second panel (120) may be a panel for displaying an image of a second resolution lower than the first resolution and a second brightness higher than the first brightness.

[0167] As illustrated in FIG. 11, the brightness around each of the second light sources of the display device can be compensated by the brightness of a plurality of first light sources arranged around the second light sources.

[0168] As shown in FIG. 12, region E can have the highest first peak brightness (P1) at the location where the first light sources (lla, 111b, 111c, 111d) are provided, and can have a first brightness (L1) that gradually decreases as the radius increases at the location where the first light sources (lla, 111b, 111c, 111d) are provided.

[0170] In the E region, the location where the first light source (lla, 111b, 111c, 111d) and the second light source (121) are not provided may have a luminance (L3) that is the sum of the luminance (L1) of the first light sources and the luminance (L2) of the second light source. That is, the second light source (121) and the luminance (L3) around the second light source may be compensated by the first luminance (L1) of the first light source (lla, 111b, 111c, 111d). Through this, the luminance of the entire area of ​​the display panel (100) can be made constant.

[0171] As illustrated in FIG. 13, the display panel (100) can form an octagonal light region centered around the second light sources through brightness compensation. Each of the octagonal light regions can form a single pixel.

[0172] The display panel (100) can have 2^(M+N) gradations when both the first light sources (111) of the first panel (110) and the second light sources (121) of the second panel (120) are driven.

[0182] The cathode terminal of the first light source (111) can be connected to a second power supply unit (132) that supplies a first reference voltage (Vss1). The first reference voltage (Vss1) is a voltage at a lower level than the first driving voltage (Vdd1) of the first power supply unit (131), and may be a ground voltage or a ground voltage.

[0183] The drain terminal of the second transistor (T12) can be connected to the power line of the first power supply unit (131).

The second reference voltage (Vss2) is a voltage at a lower level than the second driving voltage (Vdd2) of the third power supply unit (133), and may be a ground voltage or a ground voltage.

[0196] The second driving voltage (Vdd2) may be a voltage at a higher level than the first driving voltage (Vdd1).

[0197] Current can flow to the second light source (121) by turning on the second transistor (T22).

[0198] That is, when the second gate voltage (Vg2), the second data voltage (Vd2), and the second driving voltage (Vdd2) are input to the second driving circuit (115b), the second driving circuit (115b) can output a second driving current (Cd2) to emit light from the second light source (121).

[0202] A plurality of first light sources (111) can be turned on or off based on a driving signal received from a first scan driver (141) and a data driver (143).

[0203] The driving signal is a signal for displaying an image and may include at least one of the first and second scan signals and a data signal.

[0207] The data line can transmit a data signal to each of the first and second light sources, which creates a difference in color to be expressed by each of the subpixels of the first and second light sources. The data signal may include a signal for current to flow to each of the subpixels of the first and second light sources. The signal for current may include a current value or a current level.

In Paragraph 11, A data driver that transmits data signals to the plurality of first and second light sources; A first scan driver that transmits a first scan signal to the plurality of first light sources; and It further includes a second scan driver that transmits a second scan signal to the plurality of second light sources. The control unit recognizes light sources to display an image based on the determined display mode, recognizes target brightness information for each recognized light source based on the image information, and generates a data signal to be transmitted to the data drive based on the arrangement information of the light sources and the target brightness information for the recognized light sources. The above control unit is a display device that controls the second scan driver based on a scan frequency lower than the reference scan frequency when performing the second display mode.
