Description

Display module and display device including display module {Display Module and Display Device Having the Same}

The present disclosure relates to a display module and a display device including the display module, and more specifically, to a display module and a display device including the display module that facilitate manufacturing a large display device without the phenomenon in which the colors of the display module appear different.

In general, a display device is a device that receives and displays image signals and is installed on TVs, monitors, billboards, smart phones, etc., and as a means of displaying images, organic light emitting displays (OLEDs) and liquid crystal displays are used. A variety of devices are used, such as (LCD: Liquid Crystal Display Device) and plasma display (PDP: Plasma Display Panel).

Recently, as the information society develops, the demand for display devices is changing in various forms, and they are gradually becoming lighter, larger, and slimmer. In addition, the demand for flexible display devices that can change their appearance to suit various uses and environments such as buildings, interiors, and exhibitions is increasing.

A flexible display device may be implemented with a plurality of LED elements arranged in an array on one or both sides of a substrate made of transparent or opaque material, and to produce an image according to the emission of light from each LED element.

In the case of a large-screen display device, it is difficult to implement it as a single integrated display device, so a display module of a certain size is composed of unit blocks, and a plurality of unit blocks are connected to implement a large-screen display device. A block-unit display module may be configured by combining a power connection module on one side. Since a large-screen display device requires power and control signals to be connected to each unit block, each power connection module is electrically connected to each other and simultaneously receives power from the power supply device and supplies it to each display module.

Figure 1 is a diagram schematically showing an observer observing a display device 10 according to the prior art. And, Figure 2 is a partial enlarged view schematically showing the arrangement structure of a plurality of LEDs provided in the display device 10 according to the prior art.

Referring to FIGS. 1 and 2, the prior art large screen display device 10 includes a plurality of block-unit display modules 1 having a predetermined size in at least one of the horizontal and vertical directions, as shown in FIG. 1. It can be implemented by arranging.

At this time, the prior art large screen display device 10 used the same unit display module, with the unit display module 1 on the left and the unit display module 1' on the right. That is, the unit display module 1 on the left was placed, and the same unit display module 1' was rotated at an angle of 180° and then placed adjacent to the right side of the unit display module 1 on the left.

However, in the conventional large screen display device, based on the view in the direction F, the unit display module 1 arranged on the left and the unit display module 1' arranged on the right are rotated at an angle of 180°. 2, the LED elements 1a and 1a' mounted on each of the left and right unit display modules 1 and 1' are also rotated at an angle of 180°.

Accordingly, in the display module 1 disposed on the left, each RGB light emitting diode chip 1b, 1c, and 1d of the LED element 1a has an R light emitting diode chip 1b and a G light emitting diode chip (1b) from top to bottom. 1c) and the B light emitting diode chip (1d) are arranged in that order, but on the contrary, the unit display module (1') disposed on the right has the B light emitting diode chip (1d), the G light emitting diode chip (1c), and the R light emitting diode chip (1d) from top to bottom. The light emitting diode chips 1b are arranged in order.

That is, based on the observer looking at the display device 10 in the F direction, the light emitting diode chips 1b, 1c, and 1d are located on the left with respect to the center of the LED element 1a of the left unit display module 1. The IC chip 1e is located on the right.

On the other hand, in the unit display module 1' arranged on the right, the light emitting diode chips 1b', 1c', and 1d' are located on the right (positive direction of the X-axis) with respect to the center of the LED element 1a'. The IC chip 1e' is located on the left (negative direction of the X-axis).

Accordingly, the unit display modules 1 and 1' adjacent to each other on both sides of the conventional large screen display device have positions of the RGB light emitting diode chips 1b, 1c and 1d within the LED element 1a. As a difference, a problem occurred in which the observer (P1) located on the left and the observer (P2) located on the right perceived colors expressed in neighboring display modules differently. In other words, there is a difference in the color (saturation) emitted depending on the arrangement of the RGB light-emitting diode chips of the LED elements of each neighboring display module and the position of the observer.

Furthermore, due to this problem, the colors between the two modules are discontinuous at the boundary between the neighboring display modules 1 and 1', preventing images from being connected naturally.
