Embodiment Construction

[0048] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0049] Energy saving and image quality improvement have always been the areas of constant pursuit of innovation in the color TV industry. With the popularity of LCD TVs, regional dimming technology is one of the best technologies that combines energy saving and image quality improvement. The display part of LCD TV mainly includes backlight and LCD panel, and the backlight of LCD TV is the largest part of the energy consumption of the whole machine. Adjusting the brightness of the backlight in various ways can realize energy saving and image quality improvement. Existing backlights include edge-lit backlights and direct-lit backlights, such as figure 1 As shown, the side-type backlight adjusts the brightness of the LED lights 1 on the b...

Abstract

The invention provides a display module and a display device and belongs to the technical field of display. The display module comprises a first sub-display panel which includes a plurality of first pixel units and a second sub-display panel which is located at the light entering side of the first sub-display panel. The second sub-display panel includes a plurality of second pixel units. Each second pixel unit corresponds to more than one first pixel unit. Orthographic projection of each second pixel unit on the first sub-display panel coincides with the corresponding more than one first pixelunit. The second sub-display panel adopts a liquid crystal display panel with a vertical electric field. According to the technical scheme of the display module and the display device, the high contrast ratio is achieved and, at the same time, the transmittance of the display module is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display module and a display device. Background technique [0002] Energy saving and image quality improvement have always been the areas of constant pursuit of innovation in the color TV industry. With the popularity of LCD TVs, Local Dimming technology (Local Dimming) is one of the best technologies that combines energy saving and image quality improvement. The display part of an LCD TV mainly includes a backlight and an LCD panel (Open Cell), and the backlight of an LCD TV is the largest part of the energy consumption of the whole machine. Adjusting the brightness of the backlight in various ways can achieve energy saving and image quality improvement. [0003] Existing backlights include side-type backlights and direct-type backlights. Among them, side-type backlights can adjust the brightness of LED lights on the backlight as a whole to make the backlight show ove...
