Organic light-emitting semiconductor OLED intelligent blackboard

Abstract

The embodiment of the invention relates to an organic light-emitting semiconductor OLED intelligent blackboard. The organic light-emitting semiconductor OLED intelligent blackboard comprises an OLED display panel assembly, an auxiliary board assembly and an intelligent control assembly. The OLED display panel assembly comprises a touch panel, an OLED display panel, a packaging frame structure anda rear cover; the packaging frame structure is provided with an interface assembly; a control box is arranged on the inner side of the rear cover, a main terminal strip interface is arranged on a boxbody of the control box, and the main terminal strip interface is correspondingly connected with the interface assembly; the auxiliary plate assembly and the OLED display panel assembly are detachablyinserted and fixed; the intelligent control assembly comprises a power supply system, a first processor, a second processor, a signal switching module and an OLED screen driving board; the first processor and the signal switching module are electrically connected with the power supply system; the first processor and the second processor are connected through a signal switching module; the OLED screen driving board is arranged on the inner side of the rear cover and is electrically connected with the power supply system; and the interface assembly is connected with the first processor throughthe main terminal strip.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to an organic light-emitting semiconductor OLED smart blackboard. Background technique [0002] Existing smart blackboards all use liquid crystal display (LCD) as the display unit, but the liquid crystal display has the following disadvantages: first, the liquid crystal display cannot emit light by itself, so it must be displayed through a backlight module, and The installation of the backlight module increases the thickness and weight of the smart blackboard, resulting in a bulky appearance. Secondly, the black of the LCD screen is achieved by driving the liquid crystal molecules with voltage to block the backlight. Even after the LCD screen is turned off, the backlight will not be turned off. On the one hand, the power consumption of the smart blackboard will not be reduced; on the other hand , because the primary color of the liquid crystal is not pure black, the black d...

[0002] Existing smart blackboards all use liquid crystal display (LCD) as the display unit, but the liquid crystal display has the following disadvantages: first, the liquid crystal display cannot emit light by itself, so it must be displayed through a backlight module, and The installation of the backlight module increases the thickness and weight of the smart blackboard, making the appearance bulky

Secondly, the black of the LCD screen is achieved by driving the liquid crystal molecules with voltage to block the backlight. Even after the LCD screen is turned off, the backlight will not be turned off. On the one hand, the power consumption of the smart blackboard will not be reduced; on the other hand , because the primary color of the liquid crystal is not pure black, the black displayed after the LCD screen is turned off is more like gray with a greatly diminished brightness, and it is impossible to make the entire blackboard pure black. The font color is different, affecting the visual effect

Moreover, the intelligence degree of the existing smart blackboard is not high
