Embodiment Construction

[0086] Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and descriptions to refer to the same or like parts.

[0087] It will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected to" another element, it can be directly on or connected to the other element, or Intermediate elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements present. As used herein, "connected" may refer to physical and / or electrical connection. Furthermore, "electrically connected" or "coupled" may mean that other elements exist between two elements.

[0088] As used herein, "about," "approximately," or "substantially" includes stated values ​​a...

Abstract

The invention discloses a display device which comprises a liquid crystal display panel and a backlight module. The backlight module comprises a light guide plate, a first light source, a second light source and a diffusion plate. The light guide plate is provided with a bottom surface, a light emitting surface and a light incident surface, the light emitting surface is arranged opposite to the bottom surface, and the light incident surface is arranged between the bottom surface and the light emitting surface. The first light source is arranged beside the light incident surface of the light guide plate. The at least one optical film is arranged on the light emitting surface of the light guide plate. The second light source, the diffusion plate, the light guide plate, the at least one optical film and the liquid crystal display panel are arranged in sequence. The display device provided by the invention can improve mechanisms and achievements of halo and / or color cast phenomena, and is excellent in optical performance.

Description

technical field [0001] The invention relates to an optoelectronic device, in particular to a display device. Background technique [0002] With the evolution of optoelectronic and semiconductor technologies, the vigorous development of flat panel displays has been driven. Among many flat panel displays, a liquid crystal display (LCD) has become the mainstream of the market due to its superior characteristics such as high space utilization efficiency, low power consumption, no radiation, and low electromagnetic interference. As we all know, a liquid crystal display includes a liquid crystal display panel (LCD panel) and a backlight module (backlight module). Since the liquid crystal display panel itself does not have the characteristic of self-illumination, the backlight module must be arranged under the liquid crystal display panel. To provide the surface light source required by the liquid crystal display panel. In this way, the liquid crystal display can display video im...
