Title: Multi-color thin film el panel
Inventor: KAWAKAMI HIROYUKI
IPC: G09F9/30
Filed: 1990-05-15
Abstract: PURPOSE:To obtain a panel having excellent stability with the occurrence of the disconnection of a back plate and the fusion at the time of panel driving decreased by arranging a luminous layer, having thick film thickness, on a substrate side in structure in which luminous layers are laminated with a nonemission part. CONSTITUTION:A luminous layer having thick film thickness is arranged at a position near to a substrate side in structure in which two or more kinds of adjoining luminous layers are laminated with a nonemission part. That is, by laminating the nonemission part of a thin luminous layer 3D on the different level part (a) of a thick luminous layer 3C, a different level part C can be made in which a steep different level part (a), produced by etching at the time of the pattern forming of the luminous layer 3C, is relaxed. The thin luminous layer 3D causes a small level difference in a different level part (d) etching- formed, and laminating only the nonemission part eliminates the rise of luminescent threshold voltage. This eliminates the disconnection of a back plate, and also the fusion of it at the time of driving to obtain stable emission.

IPC: H04N5/445
Filed: 1989-05-18
Abstract: PURPOSE:To obtain an image of high quality having no afterimage by erasing a character display forcibly after the character display continues for a constant time. CONSTITUTION:When a specific in a key matrix 5 is operated, a character display control circuit 6 decides the ON state of the key and its character is displayed on a screen. The key-on operation raises a timer signal output signal 10 to an H level, but the signal falls to an L level a certain time later after the key is turned off, so that the displayed character is erased. Keys to which this operation is applied are a hour key, a minute key, a channel up and a down key, a sound volume up and a down key, a brightness up and a down key, etc. Consequently, the display is erased the certain time later to prevent an afterimage from being formed and the image quality can be improved.
