The invention relates to a display panel which comprises a character panel, a base and a light source arranged in the base. The character panel comprises a panel main body and a character layer, the panel main body is made of a transparent or semitransparent material, and the character layer comprises a shading area and a preset light-transmitting pattern area; the base comprises a light guide channel formed around the light source, the light guide channel comprises a light outlet channel opening, a light inlet channel opening and a channel wall, the light outlet channel opening can fully cover the light-transmitting pattern area, the size of the light inlet channel opening is matched with the size of the light source, and light of the light source is emitted out of the character panel from the light-transmitting pattern area through the light guide channel; and the channel wall of the light guide channel is black or dark. The display device has the beneficial effects that the concealment of the character patterns on the display panel is good, and a user is difficult to recognize the character patterns on the display panel when the display device is in a normal scene which is not lightened and only has ambient light; when the internal light source is lightened, the character pattern can be obviously recognized, and the light emitting effect is good.
本发明涉及一种显示面板,包括字符面板、基座以及设在基座内的光源;字符面板包括面板主体和字符层,面板主体的材质为透明或半透明,字符层包括遮光区和预设的透光图案区;基座包括绕光源形成的导光通道,导光通道包括出光通道口、进光通道口和通道壁,出光通道口可全覆盖透光图案区,进光通道口的大小与光源的大小相适配,光源的光线通过导光通道从透光图案区射出字符面板;导光通道的通道壁呈黑色或深色。本发明有益效果在于显示面板上的字符图案的隐蔽性较好,当处于正常未点亮且仅有环境光的场景时,用户难以识别显示面板上的字符图案;当内部光源点亮时,字符图案可明显识别且出光效果好。
