Problems solved by technology
Wherein, each pixel driving circuit needs to be directly connected to the display driving circuit to receive image data and clock signals, obviously, it is necessary to provide more input / output ports (I / O) for the display driving circuit, This means that there are many connecting wires between the pixel driving circuit and the display driving circuit, resulting in a relatively crowded wiring space of the display panel, and the long routing path between the pixel driving circuit and the display driving circuit, resulting in the image data and clock signal high power consumption

Embodiment Construction
[0030] The present application is described below with specific embodiments.
[0031] see figure 1 , which is a schematic side view of a display terminal of the present application. Such as figure 1 As shown, the electronic terminal 10 includes a protective layer 13 and a carrying panel 11 that are laminated. Wherein, the carrying panel 11 includes an array substrate 111 and a plurality of light-emitting elements 11a connected in a matrix and arranged on the surface of the array substrate 111 for emitting light to display images. The light-emitting elements 11a are sandwiched between the protective layer 13 and the array substrate 111 In between, the protective layer 13 is used to protect the light emitting element 11a and prevent the light emitting element 11a from being damaged.
[0032] In this embodiment, the light-emitting element 11a is a Micro-Size Light Emitting Diode (Micro-Size Light Emitting Diode, Micro LED or μ-LED), wherein the size range of the light-emitting...

The display panel is small in transmission power and large in wiring space, the display panel comprises N rows * M columns of pixel areas which are connected in a matrix mode, each pixel area comprises Q rows * P columns of pixel driving modules which are connected in a matrix mode, each pixel driving circuit is connected with at least one pixel unit, and each pixel driving circuit is connected with one pixel unit. And the pixel driving circuit drives the pixel units to emit light according to image data to be displayed so as to display an image. All the pixel areas in any column of pixel areas are connected to the same group of data interfaces, and the pixel areas in different columns are connected with the data interfaces in different groups. In any pixel area, the multiple pixel driving circuits in any column of pixel driving circuits are sequentially cascaded to form Q-level cascaded pixel driving circuits, the pixel driving circuit located at the first level is connected with a data interface to receive image data, and the image data are transmitted to the Q-level pixel driving circuit according to the cascading sequence. The embodiment of the invention further provides a semiconductor display device comprising the display panel.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a semiconductor display device using micro light-emitting diodes as light-emitting elements. Background technique [0002] Micro LED (Micro-Size Light Emitting Diode, Micro LED or μ-LED) is called a miniature light-emitting diode. In order to transfer a large amount of traditional LED arrays and miniaturization to the circuit substrate to form ultra-fine-pitch LEDs, the mm The length of the level LED is further shrunk to the micron level to achieve ultra-high pixels and ultra-high resolution. Micro LED has the characteristics of self-illumination without backlight. Micro LED color is easier to adjust accurately, and has a longer luminous life and higher brightness, and has low packaging requirements, and it is easier to achieve flexible and seamless splicing display. It is one of the display types with great development prospects in the future. ...
